Asus Matrix r9 280X = Voltage Locked?

[b3kab3ka]

Hey, I bought these cards to set up CF a few days ago and don't know how can I tune voltage of GPU? Is it enabled?
GPUTweak is showing me Vcore as 1,219 and real one according to MSI/HWInfo is 1,2560 and there is no way I can change it.

I do not have a matrix I am sorry so not able to offer any assistance.

version 2.4.7.0 of ASUS' GPU Tweak should unlock the voltages, have you enabled in settings?

[b3kab3ka]

Yes, actually using it at the moment, but changes of voltage are doing nothing to the card. It's always 1,2560V.

Also one of my cards uses different BIOS and looks like there is a bug/error/issue with GPU Voltage max setting. Look below

Who to believe with voltage? GPU Tweak or HWInfo?

Hi ... im having this problem too with my 280x dc2top . my default set in gputweak (2.4.7.0) is 1132mv . MAX: 1232mv ?????
gpu-z reads: VDDC default voltage (with load): 1.100v (+/-) . VDDC with max voltage (with load) : 1.188v (+/-)

I can't control the voltage using any other software (CCC \ AB ) .... what is hapening here ???

The voltage will and is only controlled with the specific GPU tweak version that I posted in the screen.

OP if you like you can save the bios from both cards, make a note of which is which and then test which card gives you the most control. Flash both to that bios.

The old Matrix HD7970 Platinum has a small switch right behind the CF ports... Double-check if yours have that too and if they're in the same position...

BTW, 1.4V is too much for air-cooling, as 1.363V is too!

I guess there is no additional voltage then.

so..how is that possible ? this card isn't supose to let me set 1.4v ?
