Re: Different brands Reference Rx 480. Vastly different power consumption/VDDC

Yes I did. The only difference in polaris bios editor was core clock speeds and idle mem clocks. Even core voltage is exactly the same.

Polaris BIOS Editor is a piece of shit. It's not going to tell you the ACTUAL voltages, including offsets.

What program is capable of this?

A hex editor - along with knowledge of how the VBIOS is laid out.

Not many people have that kind of knowledge.
