Hi,

Received my S7 batch 4 (4.66 TH/s), I decided to match it with 3xThermaltake SP−650PCBUS @ 80.00 CAD each, I'm in computers and the plan is to reuse these eventually in systems I build or for repair. Now, had quite a deception when I started the miner, was doing only about 1 TH/s. Checked the voltages and had about 11.5 or so.

So I decided to play with the frequency only going slower not higher, I thought I found the sweet spot at 520.83 where I was getting about 3.05 TH/s with voltages of 11.22 11.23 and 11.29. I setup some logging in a database to follow this, after a couple of days I noticed my average was slowly going down, is my miner going to die? I'm a bit scared but decided to lower even more and now it's doing even better at 508.33 with the same voltages, can I hurt my little buddy with this?

Thanks, Louis

Just so I understand, you are using 3 650 Watt power supplies for 1 S7? I want to save further comments until I understand exactly what your setup is. However I did get the 11.2 volts you mentioned and yes that is not going to be enough to initiate or boot the chips on the hash boards. These miners are very finicky about the power. Even it you were able to get it to come up you would run a lot of errors. I am surprised by this because thermal take is not a bad product. It is not my top pick, but I have run one before in my computer with no problems. For the money you spent you would have been better off buying a couple corsair or evga units and again I am assuming you are talking about powering just 1 S7. Let me know if I have my facts straight.
