Can I offload some of the heating load of my electric baseboard heaters on to two old PCs?
Hello I’m in a unique situation. I own my condo, all I have is baseboard electric heating and electricity is cheap at the moment. I also have some leftover gaming machines that are idle (unplugged) and free to use. Instead of heating my home solely with baseboard electric heating I would run the machines and do useful work and get some kind of benefit. Last December I spent over $200 on electricity. I have no plans on using other forms of heating like gas or fireplaces because that would involve renovations. Plus because this wouldn’t cost me anymore than electricity and my time, I’m ok with just having a learning experience/experiment. Small payouts are fine, I have a job. My questions are which coins could I mine? Which set up would you suggest? My first rig is a Q8200 equivalent (actually a Xeon) with 2x PCI-E x16 2.0 slots (I can run two cards in this) with 8gb of RAM and possibly a 750ti and 770. My second rig is a i7 4770 equivalent (actually a Xeon) with 1x PCI-E x16 2.0 slot ( I can only run 1 card in this) with 16gb of RAM and the 770. I can run two GPUs in a 2010 era PC or I can run one GPU in a machine with much more RAM and CPU or I can run two separate machines 1 old CPU/GPU, 1 older GPU/CPU. I was thinking I could mine easier coins and convert them to bitcoin instead of trying for bitcoin directly. Electricity is $0.12 CAD/$0.09 USD per kWh. Hopefully I’m in the right subreddit, please let me know if there’s a better spot to post this. TL;DR Can I offload some of the heating load of my electric baseboard heaters on to two old PCs?
Welcome All to the GPUMining Crash Course! With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.
What is cryptocurrency mining?
One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is... You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.
What kind of rig should I build?
You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs. For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each) There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD. Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:
Motherboard - This Motherboard can hold up to 6 GPUs (considered a full rig) with the use of risers. It is decently priced and will fit nearly any mining rig upgrades that you make in the future.
CPU - You really just need the most basic CPU you can find, it's not very essential to mining unless you're CPU mining, but even then... CPU mining isn't very profitable for how expensive CPUs can be.
RAM - All you really need is about 4GB to keep this thing running. If you want more, go for it, but it's not neccessary in most cases.
Power Switch - Doesn't need to be fancy, just needs to turn the thing on and off
PowerSupply - Don't cheap out here! Pay for a quality PSU and save yourself the headache and be safe with a solid PSU. Get a GOLD quality PSU at a MINIMUM! Platinum is good too, but probably unnecessary. The linked 1300w PSU will support most 6 GPU rigs, if you're going for higher tier GPUs like a 1080ti and above or if you're having more than 6 GPUs on a single rig then you'll need something stronger.
GPU Risers - I use this kind. They work and they're not shitty. They do require 6pin for power. Use a Molex converter if needed, but going 6pin directly from your PSU is best. Your 8+6pin will probably be a little bit short, so you'll need some 6pin extenders. EVGA will sell them you for a few bucks each, but you have to call as they're not listed on the site. DON'T YOU DARE THINK OF USING A SATA CONNECTION UNLESS YOU WANT YOUR ENTIRE MINING OPERATION TO BURN DOWN AND TAKE EVERYTHING ELSE WITH IT! SATA IS NOT RATED FOR THE POWER THAT YOU NEED!!!!
Kilowatt Meter - So that you can monitor your power consumption from the wall (much more accurate than trying to calculate each piece of hardware individually). Also helps when overclocking for a higher efficiency.
120GB Solid State Drive - SSDs are pretty damn cheap now. Just get it instead of your prehistoric HDD. Also, make sure you get AT LEAST 120GB! Many of the popular cryptocurrencies like BEAM and GRIN will demand quite a bit of virtual memory, so you'll need the extra space on your SSD to compensate for that.
Something to put your rig on - This one seems to be popular, but pretty much anything will do. I literally used a shoe rack and zip ties. You just need something that will give the GPUs airflow to breathe and keep the rig organized as a whole.
Windows 10/Linux Operating System - Pretty self explanatory here. Don't go with any of the MAC OS or Apple Products. They're extremely over priced and nearly useless in the mining world.
She's built, now what?
Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
Update Windows - Do all of the updates. Just do it.
Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.
There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on. Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit. Other Windows mining softwares include:
many more you can find from google searching
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.
I keep hearing about NiceHash. What is that?
The asshole of the mining industry. Jk, but not really. NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin. They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be. NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform. For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.
This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them. If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.
I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O
Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.** A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it: - Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have. - My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's. - I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose... - I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS. ______________________ Q2) What is your maximum budget before rebates/shipping/taxes?** * A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK). ______________________ Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.** A3) IMMEDIATELY! :) ______________________ Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)** A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\*
______________________ Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?** A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference? ______________________ Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.** A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean). ______________________ Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?** A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science). ______________________ Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)** A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well. - This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\* - I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\* - Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\* - Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts. - Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?) ______________________ Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?** A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports. ______________________ Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?** A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though. ______________________ ______________________ ______________________ **Extra info or particulars:*\* AND NOW TO THE FUN-STUFF... Here's a list of everything (PARTS PARTS PARTS) I have on-hand and ready to deploy into the wild &/or negotiate a trade/barter with: CASES - Corsair Carbide Series Air 540 Arctic White (Model# Crypto-Currency-9011048-WW) - (Probably my top pick for this build).

CLC 240 (240mm Water-cooled system CRYORIG - Cryorig C7 Cu (Low-Profile Copper Edition*) A few other oversized CPU cooling systems I forget off the top of my head but a CPU cooler is a CPU cooler after comparing to the previous 3 models I mentioned. I almost exclusively am using these amazing "Innovation Cooling Graphite Thermal Pads" as an alternative to thermal paste for my CPU's. They're not cheap but they literally last forever. NZXT - Sentry Mesh Fan Controller ______________________ POWER SUPPLIES (PSU's) - BeQuiet 550W Straight Power 11 (GOLD) EVGA - 750P2 (750W, Platinum) 850P2 (850W, Platinum) 750T2 (750W, TITANIUM - yeah baby, yeah) ROSEWILL - Quark 750W Platinum Quark 650W Platinum SEASONIC - Focus 750W Platinum ______________________ STORAGE - HGST Ultrastar 3TB - 64mb Cache - 7200RPM Sata III (3.5) 4X Samsung 860 EVO 500GB SSD's 2X Team Group L5 LITE 3D 2.5" SSD's 480GB 2X WD 10TB Essential EXT (I'm cool with shucking) + 6X various other external HDD's (from 4-8TB) - (Seagate, WD & G-Drives) ______________________ Other accessories worth mentioning - PCI-E to 4X USB hub-adapter (I have a dozen or so of these - might not be sufficient enough &/or needed but again, 'worth mentioning' in case I somehow ever run out of SATA & USB ports and have extra external USB HDD's. Although, I'm sure there would be better suited components if I get to that point that probably won't cost all that much). ______________________ ______________________ ______________________ Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc... Naturally, I have GPU's. Specifically; At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one. I also have some GTX 1080 TI's but those are already spoken for, sorry. It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP. In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well... Rig 1 = EPIC NAS SYSTEM Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL Oh, I almost forgot... The current routers I'm using are... 1X Netgear Nighthawk 6900P (Modem + Router) 1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one) 1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices. ---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :) Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years. TIA for assisting in any way possible. Gotta love the internets! THE END. :) EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here... I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent. One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind. I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids. Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).* I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows: EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else... (Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT). Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner: *** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\* Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. = 'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat. I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale. Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/. THE END (Round#2)

I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can. Preface Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here. If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier. Mining. What is it? Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section. Mining Hardware While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much. Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it. So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy. Should I mine? Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats PCPartPicker part list / Price breakdown by merchant / Benchmarks
Prices include shipping, taxes, and discounts when available.

Estimated Hashrate (with GPU overclocking) : 1900 KH/s Hardware Fundamentals CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with. RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory. HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats) GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like. PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption. MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less. PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied. When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info. Mining Software Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head) Mining Pools Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself. How do I connect to a pool? Most pools will give you a tutorial on how to but the basics are as follows:
Signup for a pool
Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine: Hardware cost: The cost of your physical hardware to run this whole operation. Power: Measured in $/KwH is also known as the operating cost. Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon. Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously. Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones. coinwarz I like this one cause it is simple. The fields are self explanatory. Try it. bitcoinwisdom I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account. Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it! More Below.
I took the plunge - 2x 7970's on their way for potential rig - I have no idea what I'm doing - Help appreciated!
So since this past Spring break, my brother in his all powerful insider knowledge on this strange thing named BitCoins introduced me to this bandwagon. I've since joined in and bought all I could muster with the funds in my bank without ruining myself and have thus far reaped a beautiful profit that my wife deems pleasant. This is, of course, something EXTRAORDINARY. Ahem. So I decided to wager my trust I've earned with her with said investment, and have decided to use a few more funds to build a mini miner. Obviously this won't be the mega tank that you see all over Youtube, Just a simple machine that may have the potential of 1.6GH/s is my hope. So this is what I've bought so far:
Total thus far after Rebates & Selling Games: ~$1300 USD Estimated 1.6GH/s with profits beginning in ~85 days (Before crash, of course XD - Now who knows!) Great thing is if all this goes kaput, I'll at least be able to resell it all! :D I have a monitor around for initial setup, and all the other obvious peripherals. What I am in need of are some tips or links in setting these 2 guys up. I'm somewhat new to Building a PCI-E Rig, but I'm sure its just as simple as plugging it all in, which I've done countless times before. I know that if I'm on Linux I won't need any dummy plugs for the DVI outputs on the other cards for it to be recognized by the OS. Can it be run purely all on a USB drive? That's one thing I'm a little unsure of. Mostly my questions consist of:
Physical Setup, if there's anything special about it all. Obviously I'll need some cooling going on. Would fan-cooling be sufficient? Or should I look into Watercooling? All I know is that if I do watercooling, I'll have to get specific water blocks for my cards.. But where to get them?
Any particular settings while using the miner program on linux to max out the performance on my 2x 7970's and 3x 7770's
Do you gain parts of bitcoins when you SoloMine, like you do in pooled mining? Or do you only reap a benefit when you hit a block of 25 bitcoins?
I don't care much for people bantering about how difficult it is now to mine, or how ineffective this might be, I've read my share about that. I plan on just having this run in the corner of my little apartment for a few months while I go to school/work/walk the dog/etc... I would like tips or any insider info on other fellow 7970'ers on how to maximize my performance with these two cards at my disposal. And of course those who do help me in my time of need and once it's all beautiful and vampiric-sparkly like will get Brownie Points in the afterlife. Last computer I built was back in 2004 so that I could play Half Life 2. And I was on a budget back then too. So I'm not too savvy with all this new cooling hardware and techniques as I've never had to deal with things that exceeded 4x AGP. I'll post pictures and videos of all the fun I have with this adventure :D Update Thus far I have only received my two 7970's and boy do they look beastly. I've never held a card that manly before. 2nd Update Everything came in! Goodness it's difficult to do a headless Linux Box! for sake of time, I think I'm just going to buy a cheap sata harddrive. 3rd Update So here's the final photo of it running with 2xx7970's I'm still waiting for the riser cables to come in to mount the other 3 cards. I haven't uploaded the videos of me building it all just yet (btw I sucked at putting it all together XD)
Lately I have been entertaining an idea that will sound radical to most people. I believe however, that it may be the best option we have to help stabilize our Western society. I call this idea, the Youth Compensation Scheme. The idea is quite simple: Upon graduating high school or upon reaching their 18th birthday, every young person receives a lump sum payment from the government. I'm sure this idea outrages people. "Great, another handout!" They will say. But consider this: Our current economic system is rigged in favor of a gerontocracy, a demographic of people born just after the second world war who believe it to be their royal prerogative to spend the sunset of their lives golfing, visiting bed and breakfast hotels, going on cruises to the Caribbean and dining in expensive restaurants. This represents a tremendous cultural shift in our society and it's not what the retirement scheme was originally intended to enable. The government originally began paying social security because people who were unemployable due to frailty suffered abject poverty. Today retirement benefits are a reward for being old. The central idea behind the Youth Compensation Initiative is that young people are a victim of an intrinsic unfairness: They are brought into a world that is owned by old people, without having a say in the matter. As far as we're aware, young people can't opt out of being born. Upon birth it becomes inevitable however that they will eventually have to garner an income for themselves. To accomplish this they are forced to sell their labor to companies. If we trace the chain of ownership, we find that those companies are typically owned by a consortium of old people. You could consider this to be a method of breeding slaves, who are manumitted upon reaching the age of 65. "But society has always worked this way and young people will eventually reap the benefits." The counterargument goes. But this is of course not true. A significant segment of young people will never reach the age of 65. Other young people will die within a few years of becoming part of the owning class of elderly. Finally, an injustice does not turn into a kind of justice simply because the victim is free to eventually turn into a perpetrator himself. There is a second issue to consider, which is that the scheme as we have come to know it is becoming unsustainable. The retirement bubble will soon fall apart, as the stock market has been propped up to ridiculous heights. To soothe the elderly, the property bubble has been inflated to ridiculous heights too. Any suggestion that young people should be kept from borrowing ridiculous amounts of money just to buy a house, or that the tax code should not reward people for their enormous mortgages, led to panic among the babyboomers because all their paper wealth might vaporize as a consequence. In other words, there's no guarantee that today's young people will once turn from victims of greed into its perpetrators. The most important issue to consider however, is that old people have garnered the wealth they have today by destroying the future of their own children and grandchildren. The threat of climate change has been known about for decades now, but no serious attempt has been made to reign in its consequences. Similarly, young people will be unable to eat fish because the oceans have been depleted and there is no guarantee that the fish populations will recover as the fundamental oceanic ecosystem has been severely damaged. Young people are also dealing with mineral resources that have been squandered by previous generations. Old people had access to cheap oil, coal, gas and various metals. What young people inherit from this is a series of gaping holes and artificial lakes in the landscape, a plastic soup in the ocean, as well as entire swathes of land that can't be farmed because of the toxic waste in the soil. We see no indication that old people sought responsible use of these resources. The American city is designed to be dependent upon cars. Old people enjoyed their high life expectancies, because they benefited from antibiotics. Today the bacteria around us are developing antibiotic resistance at an extreme rate. A large part of this problem is attributable to the fact that old people wasted antibiotics on factory farm animals kept in small cages. Americans aged 45-64 have an obesity rate of 40 percent. They used antibiotics to sustain a diet that flatters their palate but makes them sick. If old people had used antibiotics sparingly, our descendants would have been able to treat ailments like tuberculosis and gonorrhea. Today it looks likely instead that we will return to the death rates of the preindustrial era. Childbirth or a simple surgery will become life-threatening again. "Well, the old people had no way of knowing!" You might argue. But consider this: The English parliament was presented with a petition in 1376 calling for the banning of bottom trawling, because it was seen as a wasteful exploitation of the oceans. The fishers harvested such an abundance of fish that they had no good clue what to do with them and simply resorted to feeding them to factory farm animals. Medieval people similarly banned the burning of coal, because of the pollution it caused. The concept of climate change has been known about since the 19th century, but people never took the threat seriously. I'm in my mid-twenties today, so I will already be dealing with the consequences of this unprecedented wasteful squandering of the world's natural resources. There are people coming into existence today however, who will have their entire lives characterized by the ignorant greed of those who preceded them. My generation is already struggling with the consequences of greed, but this problem will only be much worse for those who are children today. I thus consider it necessary to implement a Youth Compensation Scheme, to ensure that young people today will have a chance to survive and to have a life worth living. When the Titanic began to sink, people famously urged that women and children should be saved first. They represent the future after all. Children become adults and women are tasked with giving birth to and raising them. Today we're faced with the prospect of an entire civilization sinking. For whatever reason, the idea that saving children should now have precedence over saving the elderly is considered outrageous. We're living in a society characterized by an inversion of traditional mortality. Consider the anger provoked by the very simple idea that elderly people who have lived happy lives and do not wish to spend the rest of their lives as a burden on their community should be allowed to choose to end their lives. Why do we expect people to accept being held alive, caged in bodies that no longer function? Similarly, consider the outrage provoked by the idea that student loans should be forgiven. Why do we consider it acceptable for unemployed pilots to remain stuck forever with debts that are impossible to pay back? We're quite happy for them to forego having children because of some distorted concept of what can be considered "fair". The most important thing to consider about a youth compensation scheme is that it allows us to prepare ourselves for the future that lies ahead of us. Consider the following fact: I live in a neighborhood that's four meter beneath sea level. It's clearly an unsustainable place to live. However, because my town is poor, people here struggle to leave. I work in a different town and commute four hours every day. It's difficult to relocate however, because I'm stuck in an unusual situation: I have a high amount of savings (thanks Mr. Nakamoto!), but my current job contract is for half a year. It's very hard to find a good place to rent a house however. Most places expect you to have some predictable income, even for a very cheap dwelling. A mortgage is not a good option for now either. What am I supposed to do? Nobody has an answer. Society expects me to live hand to mouth, because that's how most young people live. A Youth Compensation Scheme would result in a large number of young people who can simply pay a year worth of rent up front. It's practically impossible for me right now to find a place that's willing to make such a deal with me, because they're not used to my situation. Another obvious outcome of a Youth Compensation Scheme would be the simple fact that many young people can buy houses again. When young people can buy houses, they can start families. As a result, our population can stabilize at a sustainable level, rather than imploding until we eventually become dependent upon migrants to keep our economy functioning. Perhaps most important is the simple fact that young people would be able to move to places where they can find decent jobs, or cheap houses. The city I live in has high unemployment and mostly blue collar jobs, so I'm inevitably forced to look elsewhere as they wouldn't hire someone like me for such a thing. The economic damage caused by the fact that young people have no assets is rarely discussed. Is the Youth Compensation Scheme costly? I don't think so. I see a very simple way to fund the scheme: Stop funding college education. Rather than handing young people subsidized loans if they're willing to attend college or artificially keeping the cost of college tuition low as we do in my country, let them experience the cost of their decisions themselves. If you wish to study women's studies or sociology feel free to do so, but now it's your own money you're wasting. How many young people will still bother listening to the drivel of a neurotic old nulliparous hag, if it's not the government's money they're wasting but their own money instead? A lot of economic black holes would be closed. Important to understand is that just as poor people spend a dollar more efficiently than rich people do, every dollar spent on young people generates far higher returns than every dollar spent on old people. A twenty year old man who can afford revalidation training after an accident will generate far greater economic returns than a seventy year old man who can afford such training. A young man given 20,000 euro might use it to set up his own business. What does an old man do with such money? He buys a boat. "But young people will irresponsibly squander the money!" You say. I don't believe this to be the case. To start with, young people who want to irresponsibly squander money can already do so. It's called credit card debt. What young people can't do right now is responsibly use money, because they don't have the means to responsibly use money. If we genuinely believe that most young people would irresponsibly squander money they have access to, we should respond to that by rendering off limits to them all the payday loan companies, all the college loan schemes, all car loans, mortgages and assorted loans. But for whatever reason, I don't see old people arguing in favor of that. If we genuinely fear young people would squander the money, there's a simple solution to that: Only make the money available to high school graduates. This would eliminate most idiots from the program. The most important outcome of the Youth Compensation Scheme is that young people would be given the means to prepare for the future that lies ahead of them. Imagine fifty young people in the Netherlands believe their society is going to collapse and that their best option is to migrate to Finland, Scotland or the Baltic states and embark on setting up self-sufficient communities there. How would they go about doing that? They have no method to do so. Estonia would love to have fifty young Dutch people move to a rural community filled with old people and help revitalize it, but those young Dutch people would have no means to do so, because they have no savings. On the other hand, if every young person received 20,000 euro on their eighteenth birthday, the lot of them would have a million dollar to set up their endeavor with. Young people have a habit of setting up innovative projects. Old people on the other hand, invest their money conservatively, because they have a shorter time horizon. If something takes twenty years to pay off, you don't embark on such a project if you're seventy years old. As the world around us begins to change rapidly because of the damage we caused, it's clear that new innovative projects are necessary. We need highways designed for velomobiles, meat and mushrooms you can grow at home in a petri dish, oceanic seaweed-shelfish permaculture projects and unmanned drones flying over third world countries dropping off packages of anticonception and psychedelics. Consider the very simple case of Vitalik Buterin. Vitalik learned about Bitcoin at age 17 from his father. Around age 20 he dropped out of college, in exchange for 100,000 dollar from Peter Thiel. He began developing Ethereum. A month ago, the United Nations completed a project that sent 10,000 Syrian refugees money through Ethereum, giving them access to financial markets and thereby allowing them to build up a future for themselves in the refugee camps they live in. This was possible, because Peter Thiel used his money to enable a young man with high potential to pursue his vision for the future. Ethereum will soon move to a prove of stake model, the result of which will be that we will have an energy efficient investment vehicle that will help render the gold, silver and bitcoin mining industries obsolete. The question we're faced with is very simple: Do we believe young people deserve a future of their own? If we do, then it's time we give them the opportunity to build a future for themselves. If on the other hand, we believe young people exist solely as a source of cheap labor for the elderly, then we don't have to change anything and you can disregard everything I just said.
Me and 2 friends are going in to bitcoin mining!:O Advice/tips welcome :)
So me and 2 friends have been looking at bitcoins for a while now and we were going to preorder BFL ASICs but having not seen them ship anything and the earliest shipping date as predictable as the rapture, we have decided to GPU mine until it's not worth it by which time we should have a sweet gaming rig :P I used the mining GPU comparision to find out what was the best card, after much calculating and hunting I gave up on the idea of trying to find 4 5870's cheap and decided that the top end was probably the best bet, especially looking at some of the MH/s out the HD 7970 when overclocked. I did a lot of shopping around and I think I found some good parts at a good price too. 1 x GIGABYTE GA-970A-DS3 AMD 970A (Socket AM3+) ATX Motherboard 1 x GIGABYTE WindForce Radeon HD 7970 OC 3GB(I want to overclock this to 1100MHz) 1 x 750W Corsair Builder Series Modular Power Supply 1 x ARIAnet Titan Black Midi Tower Window Gaming Case 2 x Arctic Cooling F12 Quiet Case Fan 120mm (lots of fans:D) 1 x AMD (Piledriver) FX-8320 3.50GHz (4.00GHz Turbo) Socket AM3+ 8-Core Processor 1 x Arctic Cooling Freezer 13 Quiet CPU Cooler 1 x 4GB (2x2GB) Corsair Value Select 1333MHz CL9 DDR3 Dual/Quad Channel Kit The only things I don't need is a HDD and Optical drive as I already have spares. The total cost of the PC is £680, bearing in mind the GPU is £330. The motherboard supports Xfire so I could have 2 7970's. One of my main questions is should we get a 2nd 7970 NOW or LATER?! I've used the calculator to find out what the approximate hash rates are and this rig could pay for it's self in 3 months, sooner if the BTc value rises. We have also taken in to account the weekly power cost and worked it in to the return rate. Advice or suggestions would be great:) Thanks
