My 6-gpu rig runs fine on genoil, but in claymore one of the GPUs has 0 hashrate from the beginning, hangs in OpenCLL, claymore restarts, then the system becomes non-responsive.
Since it runs fine on genoil, I'm not sure what the problem could be?
PSU, the riser and the distribution of the power cables also can cause this. Especially pay attention on the PSU rails distribution among the VGA cards and try to move the power connectors to ensure they connect well. However some details could help: psu, vgas, risers, anything.
I assumed the problem was unique to claymore, since genoil is working. I don't understand why a riser would work on genoil by not claymore.
The cards are: XFX RX 480 8GB; MSI RX 580 Armor 8GB; MSI Twin Frozr 4 GB; Powercolor RX 580 Red Dragon 4 GB; and ASUS Rog Strix RX 580 8GB.
PSU is EVGA 1kW.
I don't remember where the risers came from.
Running on Windows 10.
