MSI 7870 hawk unable to change voltage?

post #1 of 6
Thread Starter 
I was able to unlock the voltage in the settings of MSI Afterburner and I thought it was initially working. I was able to get 1250/1350 somewhat stable but experienced a BSOD today and realized the small bump i had done on voltage had done nothing. So when I check hwinfo64 my voltage still shows 1.219 even if i bump it up past 1.3 it still wont change the voltage. Shouldn't I be able to adjust the voltage? Is there some reason it wont go up?

HWinfo64 is reading at a driver level. MSI AB can tell you what your voltage is.

What is GPU VDDC then? I am a little confused as to why it scales itself down during idle then goes up to stock gpu vcore, while MSI AB shows gpu vcore constant (and a different number of course vcore will go up over 1.3 while vddc still 1.219):



(pic shows both constant but VDDC does down throttle)

post edit:

for some reason VDDC stays constant now and memory clock is stuck at 1350 (it used to downclock too). Something weird goin on tongue.gif

Something you're running is causing the GPU to think it needs 3D clocks. This can be a number of things. I had the installer for Visual ultimate make my GPU clock up to 1200/1600. What I do now is set a 2d and 3d profile, then use the riva tuner statistics to set things to None. Just add application .exe and set it to none under detection.
