I have 5x RX480 (Saphhire Nitro +) with Blockchain drivers and custom BIOS. I'm limited to 1000W power. I'm currently mining ETH + LBRY but I have some wierd errors. GPU stops every few minutes and then starts again... I tryed lowering dcri but no help.
Now my settings are:
Clock: 1050
Voltage: 950
Memory: 2080
voltage: 950
Can you tell me what settings on GPU do you use for this combination?
I run the same set up to the following numbers:
Clock: 1160
Voltage: 900
Memory: 2020
Voltage: 920
Powlim: -10
I get 28-29 Mhs with this setting and run my machines at 1000W with 6 cards.
Good luck
