I have been unable to get my rig working at all. I have been trouble shooting for three weeks now, and still not the smallest amount of eth!

My rig keeps rebooting itself after showing these error messages:

GPU fault detected: 147 0x0be0440c
    VM_CONTEXT1_PROTECTION_FAULT_ADDR
    VM_CONTEXT1_PROTECTION_FAULT_STATUS
VM fault (0x0c, vmid 1) at page 1343356, read from 'TC5' (0x054433500) (68)
etc...

The Console field in my Simplemining dashboard says: ERROR OC GPU0

I am running 6 x 480 8GB, and there are no overclocks on anything.

I have searched through this entire thread and could only find a brief mention on page 24 but it wasn't enough to help. What could I try?
