Hello all,
I currently own 25 SP-30 and am having the same issue on all of them. They all seem to get to a certain speed of hashing and then cut out. They have been running for awhile now and haven't always had this problem. I have ruled out electricity issues and pretty much ruled out cooling issues as they run in a data center. Does anyone have an idea as to what the problem might be? I can send charts from the miners if that helps.

Thanks in advance for the help!
