Hi all
Ive got a problem with a used Thunder X3 I acquired recently. The unit stopped mining shortly after I got it. Bfgminer initializes but never starts hashing. After much troubleshooting I managed to get 2 of the Asics connected (64 chips) mining but not all 4. I determined this was a PSU issue and so bought a new OCZ Fatality Gold 1000W unit. The problem is this PSU powers on ok after I added a jumper to the motherboard plug, but if I connect even 1 x Asic from the Thunder X3 to it it instantly powers off when I turn the PSU on (I assume this is some sort of safety switch kicking in). Ive tried multiple Asic boards but still no go.
Anyone come across this before? I read that the power requirements for the Thunder x3 is 1000W as it pulls 930W or so at the wall, but assuming I'm cutting it fine with the power supply, it should still power on 1 x Asic board from the Thunder x3?
edit: The Asics still power on ok with the old Cougar 1050W Gold rated PSU, which doesnt cut the power when I connect 4 x Asic boards.
You get 996w out of that psu on the 12v rail, and it does sound like a safety kicking it, that unit is weird even when underclock for heat I don't see much a drop in power. I still think it is the PSU but I don't know much about how running a single blade works. I would probably just switch out the cougar for OCZ and use the OCZ for anothe project.
Yea thing is I dont even get to the point where I get to launch Bfgminer because the PSU powers off instantly when a blade is plugged in so I dont think it has anything to do with clock speed of the blade.
