Hello!
I have 4 7970 ghz editions on a gigabyte g1.sniper 3. Everything worked fine for some time, but now every time I try to start cgminer my system restarts.
So, first off I removed some cards. Two will work, but three or more are no good. All appear to be just fine on their own, so I'm not sure any cards are bad. I've moved them around the 4 pci-e 8/16x slots and they will work in any slot, so I don't think my mobo is bad.
My motherboard is specifically designed to run 4 cards and I'm doing so without risers (I would not advise this.) Powered risers are not needed, my board has a sata input specifically for externally powering the pci-e rails.
My power supply is a 1300W Rosewill, which I figured would be enough to run this thing. All I've got running is the cards and a sata SSD, no fans, no optical drives, nothing.
I guess I should mention that the 4 cards do just fine idling in windows, it's not until I load them up that things go south.
Anything else I should try?
Thanks for looking!
