Re: Help dual fans vs blower coolers for video card which one better for mining
In general the blower style coolers run quite a bit hotter than the dual fan open style. I have several of each and it's the case across all of them.
Could be if their stats server was down or if you lost connection up to the pool. Doubt it was anything to do with hacking. Best thing is to check your balance to see if it lines up with what you expect to mine per day/hour/etc
Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
Hi Guys
Very new to mining and the other day I disconnected the power supply from one of my S9's and I noticed that one of the power pins on the hash board side is slightly singed and a brown color.
I blew it out with air and reconnected it and the machine appears to be hashing normally, only thing unusual about this particular machine is that both fans are always the same rpm.
Can you advise if this is a problem or dangerous or if it requires repair, I have attached a picture.

It probably wasn't making a good connection. Clean it real good and keep an eye on it. If you smell burning or the plastic gets hot you may need to get a different PSU if the connector is bad. As far as the Antminer goes you don't need all 6 pins connected for it to work. I only run 4 (2 positive and 2 negative).
Re: Mining farms in the US how is demand calculated with electrical rate?
Mine are open no cooling. GPUs did fine last summer so we'll see how the ASICs perform. Worst case I'll offset the heat slightly with some AC but I don't ever plan to cool the room down to 60 degrees, that's just a waste of money.
Re: Mining farms in the US how is demand calculated with electrical rate?
I don't know what you read but your response makes little sense. I didn't say fans use zero electricity. I simply stated you don't need AC which is extremely expensive if you plan to cool a sealed room of these miners. All you need, even in a hotter climate, is good airflow from a decent quality exhaust fan or similar.

75*3.4 plus (75 * 0.4644 * 24 * 30)
Your demand charge is easy as you have constant demand. Demmand charges are really for traditional businesses which need more whatts during certain hours. Your 24/7 and can just multiply and get them.

This is largely correct. In practice your demand needs to be scaled up to account for losses after the meter in conductors and transformers. This will add 5-10%. Plus your actual usage will increase with temperature so expect an additional 5-10% for your peak loading versus the average.
You also will need to budget for your cooling load. 75 kW of miners cannot be passively cooled, so you will have to account for the fans and A/C required to keep the space in temperature control.
Free advice. Take 1/2 of what you think you will invest and just put it in bitcoins. Use the other half for your buildout. When you have things under control at half capacity and understand the profitability and risks you can make a decision about building out to full capacity.
I partially agree with your cooling statement and partially disagree. You don't need AC to cool them but you do need a lot of air movement to get the heat away. I've got around 96 KW going right now in Texas with only large fans removing air from the room to outside my building and it works fine.
That's how we are doing it. Once the coins hit our wallet we report the income at that time. You can get that information off SuprNova.cc under My Account -> Transactions -> Type = Debit_AP or Debit_MP (auto payout vs manual payout). And this is per coin.
Then figure out which motherboard slot is assigned to GPU5 when they are all connected. Then disconnect that GPU completely and try running the system.
If it's Nvidia cards you'll still see a GPU5 because they are assigned numerically by the driver by quantity of GPUs in the system, not slot or PCIE bus ID. See if that solves it, if so then you may have a motherboard issue.

I'm assuming you are using PCIE risers? Try reseating all of the GPU5 riser connections (GPU, USB), or try swapping the riser to another slot to see if the problem follows.
