You can also try to extract the bios via command line instead of using GPUZ -- also make sure you have latest version of GPUZ and check out their forums to see if anyone has reported an issue with saving the bios.

This is bios experted via atiflash command line.

I have bought a few more GPUs for my rigs. I have downloaded bios from those cards. Polaris isn't reading Timmings. Polaris Epsylon shows some strange data. Does those cards have different bioses or any other change? I Have checked memory, all of them have hynix. Anyone seen those or can share some light on the subject?

Here is bios:

Displays correctly with yours, thanks for this update! -- Dunno why I didn't see your fork until now.

I see same thing, it looks like an incorrect reporting of the mhz rated.

The timing values for each of the fields look legit though. My advice is compare against another hynix card with the same bios. These values are different than the 470 Hynix cards I have so I don't have anything to compare them to directly.

You can also try to extract the bios via command line instead of using GPUZ -- also make sure you have latest version of GPUZ and check out their forums to see if anyone has reported an issue with saving the bios.

Lastly, check the techpowerup gpu bios database to see if there is the same or similar bios there.

The only other thing I can recommend is to compare a reference bios vs this one in hex.
