Hi there
Is there any way to undervolt r9 280x under linux (SMOS/BAMT to be exact)? I've seen people changing BIOS for HD7970 to undervolt but didn't found any bios editor for r9 280x.
Anyway would rather like use software command if possible. Or I have to use Windows for that purpose?
Cgminer of course ignores voltage settings.
not the prettiest or simplest while looking for that stable voltage, but this looks to be a verified way to undervolt in linux.

Could you possibly share your MSI 's BIOS? My MSI 280x cards are locked.
