This is an amazing guide. Thank you very much for sharing all this.

As I see, no one shared detailed configuration settings for their rigs and I wanted to share what I achieved.

According to your guide, I modded bios of my 4 x Sapphire 4GB Hynix RX470 OC cards with easy way. After that, I tried XMR-STAK-AMD miner and my rig reached 2787.7 H/s. Eash card is getting around 695 - 698 H/s

I'm using Radeon Software Crimson ReLive Edition Beta for Blockchain drivers.

My Msi Afterburner settings are :

-84mV GPU Voltage
+50 Power Limit
1100 MHz Core
2000 Mhz Memory

My rig is drawing 500W directly from the wall. (The whole system.) I hope these stats help someone on this forum.

The question that I would like to ask is;

Am I using the right driver version for XMR? Do you have any driver suggestions? Can driver affect performance for XMR? Can these cards achieve 800 H/s with another configuration?

I have 30 RX cards and I just tried these settings on 4 of them. Rest of my cards are mining ETH. If I can get more 100 H/s per card, that would be amazing.

Best wishes,

You don't need to use blockchain drivers, I have 17.6.2 and WattTool is working like a charm. You may need better timings, but also conf file would help you get better hashrate.
Why you adjust power limit when you undervolting? Also you will have better hashrate when you OC memory more, but check for memory errors.

According to your latest message, I switched to 17.6.2 and changed the clock to 2050. Now, I get around 715.

I adjust power limit just not to throttle GPU.

Anyway, thanks for the help.
