HD5970 locking up in 3D

Furmak only uses 1 core on the 5970 and is a useless test for stability on a dual core card.

Let the system sit idle for a while so the vid cards temps can drop and stabalise then run some 3DM06 or Vantage or Stalker COP benchmark.

@ Jooney. You should run furmark fullscreen and even more importantly, disable MSAA. At 1ghz your VRM Current Draw should be able 80 amps. It's currently about 50amps. That will make a huge temp difference on the VRMs. I'm interested to see how this block performs under some real stress.

Without MSAA its about 100° sure,but thats only a Furmark thing,no real scenario have those temps,during Vantage with 1000/1200@1,2 highest VRM Temp was 50°.
So massive heat on very little spot can no cooler handle.

This was Furmark with both GPUs,look at the screen!
Vantage,Furmak or idle whats else it runs fine :confused:
Here another screen with MSI Afterbruner in it where you also see that both GPUs are running during Furmark.

Current reading seems really low though.. I am seeing 65A at the same settings (1Ghz core @ 1,2V) running milkyway@home and double the VDDCI current as well...
