Hello miners!
I recently got my first video card, a Radeon Sapphire RX 570 pulse 4GB. It's the fist time I'm modding a bios and I could use some help to optimise my card. I decided to mine Monero, and the only thig I know about mining is from Mattthev's tutorials about Monero mining and bios modding.
GPU-Z shows Elpida memory, and I modified the timings in SRBPolaris only for Micon-Elpida (the card has also SK Hynix memory). First i tried the timing recommended by Eliovp and Mattthev and after that I used a timing optimised by laik2, that Eliovp said is more stable. I c/p it to 1500, 1625, 1750 and 2000.
The timings are:
777000000000000022AA1C00315A5436A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715
777000000000000022339D00CE515A398055111230CB440900408400740114206A8900A00200312 0150F292F94273116 - optimised
The other modifications I made are:
- GPU frequency from 1284 to 1300 MHz
- MEM frequency from 1750 to 1900 MHz (more gave me memory errors)
- Voltages from 1000 down to 950 Mv
I am using Win 10 with blockchain drivers.
After modding I have a constant 780H/s in XMR-STAK-AMD 1.4.0 Official release, with few memory errors.
Can I get more H/s from my card? If so, can you please help me with some sugestions? Power consumption is not an issue. I want maximum performance!
Thank you!

Yeah some of Elpidas can't have higher memory clocks. You might also need to tweak miner config and switch to compute workload.
In the Monero guide guys posted some of the best configs, you have to use 2 threads for best performance.
