Re: Sapphire Nitro+ RX 570 OC 4gb - can't get it past 25mh/s

I have the same exact card. Currently hashing at around 31mh/s using claymore 11.5, my bios setup are core clock 1050, memclock at 2100, I have to lower memclock to one card to 2090 because of mem errors. And I'm using Trixx to undervolt and getting 910watts for 6 cards in dual mining and about 770watts in ETH mode.

Wow, so you actually just lower the memclock by 10, and the card is running?
I'll have some work to do.. The problem is that when i run 1 single card, it is no problem getting 29-30 mh/s. It is when i run more than 3 in windows..
So I'll do some testing in ethOS just by changing the memclock to 2000. on that exact card.. That gave me 29 mh/s. I'll see if i have to go lower.... I am not familiar enough with ethOS to know if there is a "HWinfo" program working on it.. I get sick from windows Grin

The cards that need lower memclock. do they need higher voltage?
