Rx 470,480, 570 cannot undervolt

[burundi]

My Windows 10 Polaris Rig won't undervolt

- I tried the claymore command line -cvdcc
- I tried OverdriveNTool 0.2.5
- I tried MSI Afterburner v 4.5.0 (the vcore is greyed)

I attached a sample picture of my RX 480 Card. The Vcore should be 825 but it's 918 ( GPU-Z and HW Info show the same high vcore)

How can I fix this problem?

You can do it yourself by using the tools to flash your Bios and manually configure all the settings in polaris bios editor.

If you don't mind spending a low amount of money you can find really good bios setup on mining-bios.eu

Note: I am in no way affiliated with the site, they just happen to make very good bioses for mining for each rx series.
