I just want to mention, this driver is used for more then a week, I personally use it and my friend with huge pool, with more then 600 gpu's, all of them 470/480, working like a charm.
Just to be clear:
1. You must use Clymore v9.8
2. Use -cclock / -mclock in Clymore, to control clocks of your gpu's
3. For voltage use AB, it is working well. I personally test, voltage control working fine via AB, fan control to, just gpu/mem clocks need to be used via Clymore commands.
There is some minor bugs with RX570 cards and new Clymore, but it is also something what can be solved easy.
robin, i have rig with 8 gpus rx 580 gigabyte and test the driver. i use claymore v9.8 with clock and vddc settings without AB. after i update with fixed driver my hashrate drop down to 15 - 20 hash per cards. what would be the reason for this problem?
