    Great Article! I just shared this with my partner. in addition to the 10 AntminerL3s we have on order for November we have discussed buying or building a GPU Rig. this article goes along way to explaining exactly what and how to do so

      Nice thing about GPU rigs is you can get everything you need in a week, and start mining right away.

    Rolf – I appreciate your articles and videos. I hope to have my first miner up in my home in about a week as parts come in. I have two quick questions: 1. What is your set up for running GPU miners at 240V? 2. Have you looked at ASRock H110 Pro BTC+? It can handle 13 GPU’s, and it would seem to be a better investment from a power and hardware standpoint. But I haven’t seen anyone with experience with this board.

      1. I plug the 240 VAC into the power supply of the GPU miner. It likes higher voltage, because there is less current.
      2. I’m not ready to increase the amount of GPU’s per mining rig yet. The most expensive part of the system is the GPU’s, and systems can be somewhat unstable – at least for me. It does not really save much money. But maybe it’s the future – I don’t really know.

    Rolf,

    Have you looked a shrinking cost/unit by using different components? I hear you on the reliability argument, but since you have a nice facility in which to work where noise isn’t a concern, why not try server psu with a breakout board? I’m playing around with a unit from parallelminer (from whom you source your rigs) that I quite like. It’s a bit too loud for the test stand at my desk under but I think it would work well in your facility–and it’s a fair bit cheaper than buying 1200w ATX power supplies.

    Keep educating!

      Thanks Wood! I go back and forth on that. I have some server PSU’s in my smaller shop and it works well, but it adds complexity as well. With almost 200 miners now I need something reliable and simple.

    OP, what would you recommend to get started on a $3000 budget? One of the rigs in this post, or 2 Antminer t9s or s9s?

    Love the site and I must tell you that I stumbled across you while researching distributed ledger technology for a paper in my Masters Finance class. 4 hours burned down this rabbit hole and I’m hooked on crypto mining. Enough! must get back to my paper!

      Thanks Nathan! I would not start with an Antminer S9. Would probably order an Antminer L3+ and a power supply from Bitmain, or would build a GPU miner to start.

    Super article, learning so much from your site Rolf.

    I really like nvidia cards, have you done any comparisons on the card/mem types for 1070 and or 1060?

    I also find if you want to use a PC to talk to unix CMDER is your best bet. Super BASH like with git,vim and all the goodies in it. Plus it looks good and it runs claymore output fine remotely as well. Although sometimes if you use screen or TMUX it can get a bit weird on refresh.

    Also I found a good way to see my usage more accurately on the NVIDA overclock outputs was to call

    watch -t 2 nvidia-smi

    in a console to see the voltage use, its kind of like a virtual HTOP for my GPU’s when I do tuning found it really useful.

    Have you had much experience or result using nicehash compared to pool? They always seem to come up high on whattomine etc.

    Nice article, and I today I was about to buy a similar setup. But I’m struggling to convince myself to spend 3000USD on GPU-miners. Difficulty of all GPU-minable alt coins has exploded and still grows exponentially. Low coin values also doesn’t help, but the rapid increase of difficulty makes mining seem pretty stupid: you hardly get any coins from mining.

    So even if prices will increase, isn’t it more profitable to spend those 3000USD directly on an exchange and but some ZCL and NLG?

      when I run the numbers it never seems to make sense to mine. But then I do it and it is profitable. At least for the last 2 years it has been.

      Not sure about ZCL or NLG right now. I don’t understand either project and what their goals are. I stay away from things I don’t understand.
