Anyone can helping for me?
I have two RX580 (Asus ROG-STRIX o8g and Asus Dual-OC-4g), and I dont know how to do it... Sad

You can try some of my pimped strap timings for Hynix:

rus_mod hynix

But for me this tool is unnusable because when applying timings it gives artifacts and crashes driver no matter which timings i apply (Polaris - rx570 & rx580).
I got the values by decoding hex values of timings with R_Timing1.03 tool.
