I've not seen ANY LINUX tool for AMD cards that allows voltage control at all.
UC is also problematic - ATICONFIG will let you set an underclock, but the card then IGNORES it in all of my experience with it on dozens of different cards.
Ditto CCC for LINUX.
OC on the other hand works just fine.

have you tried AMDOverdriveCTRL, atitweak etc?
before you could set Voltage settings you have to enable this feature elsewell it will ignored due GPU.
don't talk bullshit about OC/UC, OV/UV when you only don't know how to do that ...
AMDOverdriveCTRL was never updated for the R9 290 or R9 280x, in my reading about it - and it flat out didn't do voltage adjustment on quite a few of the cards it was SUPPOSED to work on (locked BIOS issues was apparently the concensus on those cards).
I tried to download atitweak from somewhere, but it came up as virus infected, and I never found anywhere else I COULD download it from that seemed like a legit site.
Academic point on the voltages at this time, since I DID find working copies of TheStilt BIOS series and don't need to worry about LINUX-specific voltage mod tools any more.
