Title: Only 18 MHs With Rx580 [Help a Noon] Post by: Danny110 on December 22, 2017, 05:09:19 AM 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

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.

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://bitcointalk.org/index.php?topic=1954245.0 Title: Re: Only 18 MHs With Rx580 [Help a Noon] Post by: priviet on December 22, 2017, 10:49:19 AM 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 |
