Hi everyone,

Being an nvidia miner, yesterday I spent some time installing my first Radeon GPU and trying to optimize it to get the best results and performance

The GPU is an MSI Armor OC 570 8GB, I'm using Windows 10 with latest creator update 1709 and using the latest adrenalin 18.2.1 drivers and a mod bios

Below are the steps I went through with the different results:

1- Stock settings: 17.9 Mh/s
2- With compute mode enabled: 24 mh/s
3- with mod bios: 3̶1̶.̶7̶ 30.7 mh/s
4- Using afterburner: OC memory from 2100 to 2150 and setting -20% power limit :3̶1̶.̶7̶ 30.7 mh/s , power draw as per GPU-Z is 110w

That's the best efficiency I could achieve, tried further lowering the power limit but it resulted in hashrate drop

I did search in the forum for undervolting the gpu but I'm still confused with it, my afterburner has the core voltage grayed out even though I enabled it in the options, watttool doesn't seem to support the RX500 series and not sure if it is possible to undervolt using Polaris

Any ideas how to lower the power consumption below 110w while maintaining the same hashrate ?

Thanks
