I'm running Ethos with a 6 GPU rig (RX 580 and Mobo is H81 Pro BTC R2.0).
After overclocking/undervolting, i get a satisfying hashrate at ~170 MH/s for 950 Watts (from the wall), GPUs are running under ~55°C temperature.
My actual problem is am getting the 6th GPU to go off randomly after a couple of hours, in claymore i get the following error:
WATCHDOG: GPU 5 hangs in OpenCL call ...
I've gone investigating the issue, here's my results:
- Changed the riser, the cables and the power cable of the riser: still same issue
- On Win10, the system could not detect the 6th GPU ! i can only see 5 GPUs just on system startup and not after running couple of hours of mining like on Ethos
- Cleared CMOS, same result
- Undervolted and underclocked down to 24 MH/s, still same result
Any idea guys ?
