MSI afterburner voltage problems

[Fisher]

I have an odd problem. GPUz says my voltage is at 1.2000, whereas MSI afterburner says it is at 1.110 and Kombuster says it is at 1.150.

Also, whenever I change the voltage in MSI afterburner, it doesn't affect the GPUz reading, and also sometimes changes the value. For example, if I put it to 1.175, it changes it to 1.174, though I'm not sure if this has anything to do with it. I'm pretty sure it doesn't change the voltage at all, as I am not able to overclock even slightly higher than my set value (max core clock is 910).

I have unlocked voltage control and monitoring, and I have enabled unofficial overclocking.

Here's my rig:
Processor: AMD Phenom II X6 1075T Processor 3.6 GHz
RAM: 8GB
System type: Windows 7 64 bit
PSU: 750w
GPU: MSI ATI Radeon HD 6950 OC Twin FrozR III Power Edition 2048MB GDDR5 PCI-Express
Motherboard: ASRock M3A770DE AM3

have you tried using asus gpu tweek instead, works a charm for me and has the lovely noob friendly slider bars and keyboard input areas, GPUZ attaches to it and updates within a second when i change settings.

I have an MSI 7850 and GPU-Z doesn't correctly monitor voltages on my card. It shows 1210 whatever I set in Afterburner, but I know the voltage changes because the temps vary according to voltage and my OC stability depends on what voltage I set in Afterburner.

If AB is working for you I'd forget about using GPU-Z to monitor voltages because it isn't always accurate. If you want to check whether AB is controlling your voltage have a look at the GPU temp with different VCore settings, same clock speed.
