6970 - Problems under cold

[T_M]

Both Monteboy and I are suffering the same problems with 6970 cards subzero.

For me, anything below 5C pot temp causes significant corruption to the point where the whole screen is fireworks. But it still benches and completes runs. In 2D the desktop is covered in small green dots.

Can someone knowledgeable please hazard a guess as to the cause?
My card is modded with all the VRZone mods.

I have made a video showing Heaven DX11 running at temps from about -8C to +8C and you will see the corruptions suddenly disappearing around 5C

Nice...

Do card clocks effect it at all, or is it only temperature ?

Seemed to be only the temp.
It did the same at both stock and 1100/1450
