Step for step guide:
Download AMD Blockchain driver or adrenalin driver (you have to set to compute mode)
Mod your driver with
https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher
so it accepts modded bios
Download bios from your card with atiflash 2.77
Modify it with https://github.com/jaschaknack/PolarisBiosEditor
Use one click timings if in doubt
Reflash your card with atiflash and the modded bios
Reboot
Enjoy 28-32 MH/s
Topic: Only 18 MHs With Rx580 [Help a Noon] (Read 130 times)
Hi Guys, I am recently setting up an Ethereum mining Rig. I have installed Ethos, played around abit. So far, it's running Okey. The only issue is, that I only get 18 MHs from my RX580 from Sapphire, it is just out of the box, no optimization yet. I have 2 questions. Does anybody can assume, where the problem could be, and is there a Tutorial how I can optimize the Card to it's best? Thank U
GPU0 28.305 Mh/s,GPU2 27.949 Mh/s, it's my 580
You need to change Bios timings to get the 28 MH/s, but it for your own risk.
So, use this manual. https://bitcointalksearch.org/topic/guidetutorialxmrethhow-to-mod-bios-rx470570480580-vega-mining-1954245
For the default settings, 18 MH/s seems fine.
Now, to reach higher values you have to tweak some settings and you can have around 29-30 MH/s.
Bios Mod your driver according to your GPU company (Sapphire, Asus, MSI, etc.) and memory Vendor (Samsung, Hynix, Micron, etc.)
Undervolt your core, Overclock your memory, use -dcri 6 when single mining and -dcri 30 when dual (claymore command line bat) for best hashrates.
