I have a 4 GPU rig 2 vega 56 and 2 vega 64 but before I buy my second rig I want to get this thing hashing. I currently am getting around 6400-6500 hashes with all cards which I should be getting around 8k. But it keeps shutting off. I have a 1000W power supply. so maybe thats why? But if anyone could help would be greatly appreciated in terms of their settings. I have included screen shots of what mine look like that keep going for around 7-10 days.
