6950 Temperature Sensitivity

post #1 of 7
Thread Starter 
So for laughs I put my core clock at 950.
Seemed okay, started furmark.

No artifacts until I broke the 77-78C barrier.
Started artifacting moderately.
Turned up the fan speed to 100%, once the temp dropped under 77-78C the artifacts completely went away...

Thoughts?

...thanks for the enlightenment....

Widespread/known issue?
Any particular reason why it would choose to start messing up at those specific thresholds?

Ok seriously I would say its probably more to do with the overclock not being stable than the temps, unless of course you can replicate the artifacting at 77C everytime.

Not really sure what cause it but some components does not like heat.
I remember someone got artifact with his HD 4870 even at stock speed because of too high temperature. He overclock the card. The card goes too hot. Artifact shows. And it doesn't disappear even when he reset the clock speed to default.

Apparently I suck at remembering things and it's actually 83-85ish range.
Here's a video, kind of long (3min) but shows how it's easily replicated..
