It's not the cpu, its 30 pass linpack stable and 12 hours orthos stable at 4.5GHz @ 1.336v load. Just hates 3D apps at that speed. Ive tried everything and nothing works.

Tried it just now out of sheer frustration on my P5Q-D and it's even worse. I am considering grabbing an X48 board to try it out but it's a fair bit to spend to bench.
I can't believe that your board can't handle it. I'm running @4.5ghz (530mhz fsb) 24/7 for the past months without a single prob...
