Anyone suffering from the nvllmvm driver crash?..."Driver has stopped working but has recovered" error.
Drop your RAM to 666MHZ (333MHZ).
It appears its a hardware issue when RAM is out of sync with the FSB over 800MHZ.
At the moment I'm trying it with my Q6600 @ 3.0GHz (1333 X 9)
I'll confirm with further testing over the next few days.
Before anyone starts flaming
D) it hardly touches framerate...I've only dropped a couple of hundred marks in 3DMark 06.
Its not ideal but will mean that your PC is useable rather than crashing out of games every few seconds.
