This bios is not working on my gpu

You can use bios from sapphire RX570
2048sp it renamed and overclocked RX570

Hi, you can ty the following that has the correct subsystem ID "E396" but Samsung memory that has often very similar timings to Hynix. If it doesn't work you can manually replace the timings with the tool PolarisBiosEditor from another bios with the Hynix memory.
