Hey guys, I faced an interesting and annoying problem.
I have a 6 RX570 rig (5 samsung 1 hynix+elpida)
I successfully managed to get 29.5MH/s 1100/2000@838mV.
First minor problem, I couldnt lower the voltage below 838mV nomatter if I set it to 800, it stuck on 838 or higher.
But my main question is, I tried to increase the memory clocks, I set them to 2100 and only the card's (which one is connected to a display) hashrate increased to +31MH/s, all rest of the cards Hash did not changed. In afterburner I seen the clocks were applied to all cards, tried Cryptonight algo and the OC worked there so it shouldnt the cards.
I tried to increase voltage, Core clock, powerlimit, different versions of Claymore, different OC apps (Claymore too) nothing helped. I restarted the pc, the miner, used the numbers to disable the cards nothing.
