I have a rig with 6 AMD Rx580 and 1 Amd Vega 64.
I have problem with Vega because it is giving me 20 % invalid shares.
So far I tried
- Replacing the riser
- Trying a high hash rate more power usage OC setting for the card
- Tried a relaxed low power usage setting for the card
I have a different 6xVega 64 rig with the same exact card and I am getting 49 MH/sec per card and rarely any invalid shares.
But in this rig, despite I am using less OC I have huge amount of invalid shares.
Does anyone have any suggestions that I can try?
