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!
