I'm just struggling with the Vegas.
Doesn't seem to matter whether I increase voltage or lower clocks, after a few minutes mining Monerov8, all GPUs go boom, i.e. SRBminer says hashrate is zero for every single card... and it will fail automatic re-initialisation.
Using 120/16/2. They're all 56's flashed to 64.
Maybe I'm just at the limit of what the PSU is able to cope with... Power draw is between 1400 and 1435 for a EVGA 1500 G2...
hmm .Mybe. my 6 nitro+ vega 56 use 1170W on V8 and 970W on V7 from the wall. i have 2*750W PSU and all work...
just try mining with 5 vega.
just del last gpu { "id" : 5, "intensity" : 120, "worksize" : 16, "threads" : 2},
and try.
if work your PSU is problem
