HD6950 voltage issue

Sharx69 · May 23, 2012

Hey TPU peeps,

I recently bought this card: XFX HD-695X-ZNFC Radeon HD 6950 1GB 256-bit GDDR5 ...

It works and everything, but when I adjust the voltage in MSI afterburner, I start getting artifacts on the screen.

The amount of artifacts increase with the voltage level.
It should be stated that this happens, when the card is not under load!

Does anybody have a clue to what causes this issue, and perhaps a possible fix?

It would be much appreciated

will post a video soon, displaying the issue :/

That particular card is very much cut down from the reference 6950. It is most likely not designed, not capable of overvolting.

Try Sapphire Trixx instead of AfterBlunder.

I have a reference Sapphire 2GB 6950 and use Afterburner all the time.

No problem with voltage mods, except that my particular card seems to need more voltage than others. Personal problem I guess.

My standard OC is 900/1440 at 1.175V.

Yeah their well known for it and best to do your research before buying.

I like to know what voltage he's is trying to set it to.

i have your same model but with dualfan , use sapphire trixx i have oc without problem at 900 for the core and 1450 for the memory voltage at 1.100v

Thanks for all your replies

I'm trying to set the voltage above 1.1V
The reason why I bought this card, was that it was under half price, with a two year warranty.

Will try trixx this afternoon...

Okay, tried to use Trixx. Same issue with the artifacts. I can see from gpu-z that the voltage actually changes, according to the sensors at least...

This is driving me crazy :/

Honestly, I would RMA the card due to this fact. It should not artifact just by raising the voltage in the slightest.
