Guys, I have a strange Problem. Hope someone is able to help me. 0.05BTC bounty for getting my miners to atleast 2,6 Ghash each
I got 16 Antminer U1. All are running at 1,088 V. I have a 49 Port USB Hub and a 450W PSU exclusively for those 16 U1. I have additional coolers attached and a fan blowing cool air. The Miners get definitely not too warm.
I tried Bitmain´s Cgminer, different BFGminer version on Windows, Minepeon and Raspcontrol. Cgminer gave me too much errors and for BFGminer I have the following Problem:
While I should be able to get 48 or atleast 44,8 Ghash out of the 16 U1, I get far less. Recently did some testing with BFGminer 3.10 and Raspcontrol
At 4D81 I get 6 Ghash
At 4C81 I get 10 Ghash
At 0B81 I get 12 Ghash
At 0A81 I get 15 Ghash
At 0981 I get 14 Ghash
At 0781 I get 10 Ghash
The Problem here is, that most Miners run somewhere under 500 Mhash. No Hardware Errors. Those U1 who do more Ghash are getting warmer then those who only do some Mhash. From test to test the variance is very big.
Currently they run with 4C81 under BFGminer 3.9.0 and Minepeon with 25Ghash. For some reason the hashrates with bfgminer 3.9.0 are similar among all sticks. The best result I got so far was about 30Ghash (also BFGminer 3.9.0 and Minepeon). The funny thing is, that I didn't give any frequenzy to BFGminer in this test so that the Miner should have run with 1,6Ghash. For some reasen they did nearly 2Ghash. This was absolut stable (ran for <24 hours). Again: I do not get any errors (or very very few on some sticks <.1) beyond 4E81.
Sorry for the bad english
Thanks
