Rx 580 8gb oc


i got two rx 580 8gb, one is sapphire pulse other one sapphire se. Both of them are flashed via polaris and now both of them running with around 32 mhs with 110W. Couldnt i get higher mhs or lower consumption? Below is my settings.


RX570/580 with Samsung memory consumes power between 102-117. That’s normal.
As for going for more hashrate, I won’t recommend that since the rig might become unstable.

I’ve ran 33.5 hash for days on 85-90 watts on 3 580’s and one 590. Rebooted recently but ran 4000 shares without an invalid.

What brands of those cards do you have? And which memory? Mine 580s are both sapphire. One is pulse and one is se.

I have all memory’s one is Samsung, micron, and Hynix. The 590 is micron also. 2 are sapphire pulse one is msi.

The bottom settings are sapphire Samsung, the second is sapphire micron if that helps. I went very slowly in the ramp up. I found if I immediately changed it kicked shares but could have been coincidence

And what miner do you use? Phoenix miner?

For some reason, my RX570 8GB only gives me 26 MH/s. I am using the same oc settings as you and flashed the vbios.

That is weird, but seems to me that you have too low consumption. Maybe try to set your voltage higher. Anyway on my other 570s i use these settings.
