The next step

After flashing video cards, it might be necessary to patch the drivers of the operating system in which the BIOS is checked for correctness. It is possible to do it using the Atikmdag patcher program.

The program is usually required for RX400 series video cards, which are detected after BIOS modification by the system with error 43.

In addition, the GPU-Z and HWinfo programs are convenient to use for the control of the parameters of the video card. They show voltages, frequencies, loading the video card, and much more useful information.

Hi I am setting up an RX580 rig with 12 cards and I currently have 3 cards connected. I can't get more than 29.7 and they are all Gigabyte with Samsung memory. Can anyone please advise what I can do to fix it? My cards are not modified in my BIOS.

Try using the overclocked settings from the Hive OS forum. You should get more

I tried and used all the different settings, the only thing that worked for me was to use Polaris Bios Editor 1.7.3 to modify the biography and use the settings that the BIOS editor told me. Now all my cards are running at 31.7, which I think is the maximum for these cards.

Which miner?


hi, i tried these on my 570 samsung, exactly like u said 31.xx, champion ! Thanks for sharing
