Does anyone else have this happen? Using RivaTuner to monitor the gpu/memory clock speeds & gpu/ambient temps while running the 3DMark03 demo gives a consistent result. During demos 1 & 2 the gpu clock speed runs at the 3D rated speed; however when demo 3 (troll) starts up the clock speed goes to a speed halfway between 2D & 3D. It stays at the halfway speed again for demo 4 (nature). In-between each demo, the gpu clock speed does drop to the 2D speed. At first, I thought it may be due to high temps; but the temps never get above 80C during the demo. And I have seen the temps get above 80C during the 3DMark03 benchmark and during 3D games. This gpu speed problem for demos 3 & 4 is consistent and repeatable every time. BFG Tech Asylum 5900nu.
