6950 Freezing 3DMark06!?!

post #1 of 7
Thread Starter 
GPU - HIS 6950 2GB unlocked shaders Driver 11.3

When I first put it in I overclocked I to the max afterburner would do 840 1325 but FORGOT to change the CCC power thing to +20%

Tried to run 3D Mark 06 and it froze on a black screen at initial load up

That was the first freeze, I set the CCC and ran 3D Vantage, 11, and 06 at stock 800 1250 and all was well.

I then OC'd to 880 1350 @1.21v and ran 3D Vantage and 11 with no problems.

When I ran 3D Mark06 at these setting on what seemed like the very last frame of the "Deep Freeze" section it froze. Couldn't get out and had to hard boot.

Any ideas? Driver? Overclock? Temps are good 70C max there abouts, voltage seems more then enough compared to others (6970 runs those clocks @1.175v or so I read).

Thanks guys.

It sounds odd, but DiRT 2 is the toughest stress test I have ever used on a video card. Even harder than furmark

What is your voltage for 920 core?? Could it be my memory OC to 1350?

if it freezes in 3dmark06 or eleven during graphic test then it means there is not enough voltage going to your gpu's to run at that clock speed. i had the same problem with my crossfire 5770's after bumping them downing to what they were when i first got them then it was all good.

I had the same experience as Grumby with this card. Was 100% stable at 950 MHz with 1.25v in anything except 3DMark06 where it would freeze and driver reset. I had to bump voltage up to 1.30v and everything was golden.

Should the voltage concern me up to 1.3v if the temps are fine? Like life expectancy? And don't get me wrong by life expectancy I mean by the time I want to get rid of it, 1 year max!!

Also it did crash on the graphics test in 06 but it was the very last one "Deep Freeze" and at the very end of it? Still for sure core voltage?

You can try 1.30v to see if it stops the crash. I'm sure just doing a 6 minute session with safe temperatures won't damage the card.

If it does, then yes, it's a voltage issue.

As for long term safety, no one knows for sure. But generally, if you keep the GPU well cooled, you should not have any problems.
