My Sp 20 is disconnecting/ stopping mining for no reason. I have 1300PSU platinum going and it keeps knocking itself offline. The fan is still running so the only way I can tell is when I log into it, which I can't do at that point. I log into my stats page on eligius and I can see I am zero hashing. If I reboot PSU then it comes back on. Seems to be happening between every 4 and 24 hours. Is anyone else having this issue?
I have reset to factory and now trying to run. we will see how this goes.
lower your watts setting to 250 and drop the all the volts by .005
you are taxing the psu.
My seasonic 1200 strains to run this and I have to use lower settings then my evga 1300's
PS: I'm running mine on a pair of CX750's though and have been having this issue too... any suggestions/advice?

well my thread has tests for 5 sp20's they are more like 1400 to 1500gh.
Unless you can stand the noise and have really cold air. Since all 5 are in my garage directly under my bedroom. I have no choice but to do massive under clocking.
1350gh
I can say that these are not a 1700gh miner do -10%
which is 1530gh work from there.
