Hi! I recently purchased a used Antminer S3 from eBay, never overclocked, run in a clean environment. I've been running it for a few days now and I've noticed that the readings are always just around 400 GH/s on average, which seems to be a bit too little for me. On Bitmain's website, they say it runs at 441 GH/s +-5%, which still should leave me with about 420 GH/s at the very least. I am running at a clock speed of the default 218, all chips are working according to the web interface. Temperatures never go over 37 degrees. Am I doing something wrong, or did I just get a bad miner? Is there anything I can do to increase the hashrate? I cannot overclock, as my PSU only has 2 PCI-e connectors. Thanks.

The network tries to produce one block per 10 minutes. It does this by automatically adjusting how difficult it is to produce blocks.

I was a bit low on money, so I just picked up a Sentey 625 watt PSU and I'm using that. I also have a Corsair CX-500 running my overclocked Antminer S1 (I don't have to worry about power costs). Would that be better? I was planning on trying later tonight.

Oh, dang. That's a shame I guess. I'll switch PSUs over. I don't care about the S1 as much since it draws more power anyways. The reason I got it in the first place was because someone else running the same set up as mine had the 725 watt version and was able to run an S3+ and the new R-Box 2.0 off of his, no problems. Guess I'll just have to deal with what I have and make the best of it. Thanks for your help.

Switched out the PSUs and the S3 only ran at something like 13 GH/s. At least that's what it said in the average. It had solved 60 but rejected 500 in the few seconds I had to open the interface. Let it run for another few minutes, no change. I just figured it didn't have enough power even though it should; 450 watts on the 12 volt rail and the S3 only takes 355. Oh well. I switched back the PSUs and... worse? .19 GH/s... Fantastic... Letting it cool down for 10 minutes, that always seems to fix any problems I have. I'll see how it does from there. Hopefully I didn't damage it, I don't see how I could have.

Although the S1 ran fine on the Sentey PSU. No problems at all. Same as the Corsair I had been using for months.

Reset the S3 to factory defaults. Seems to have fixed that problem. I'll let it run for a day to get another average to make sure and then try to switch the PSU again.

for the bitcoin Miner, please select 80 Plus gold or plat. Little investment into the PSU makes a bit difference in a long run Reset the S3 to factory defaults. Seems to have fixed that problem. I'll let it run for a day to get another average to make sure and then try to switch the PSU again.

Yeah, I've noticed :/ Not a good PSU. It's only running at 366 GH/s now. Thanks for the info.
