R9 280 unlock voltage

[kylew_is_back]

Hi,

I recently bought a 280 to CF with my old 7950, but Msi aftarbener doesn’t give me voltage control for the sapphire R9 280 like it dose with my seconded GPU 7950, basically I want to lower the voltage for the 280 because they are too high for the MHz I want. With the stock voltage the 280 is stable at 1140MHz, and I just want 1050MHz, and it is getting too hot (86C, and above that it always crashes), I mean I am getting the same temps at 1140MHz and 1050MHz or at 925MHz.

Obviously I have try things like UnofficialOverclockingEULA, UnofficialOverclockingModeand and every related settings.

For now use TriXX to change the voltage for the 280 (from v1256 to v1125) but I prefer the msi afterburner, and I don’t like the idea of runing both at the same time.
Any suggestion?

Thanks

Flash the bios of the first card that works with MSI to the second card. It might work and give you voltage control, but there is no guarantee.
