Right, in the meantime it turned out that LLC off doesnt help a thing, tough the rig could take LinX a bit longer (30-40 pass) eventually it locked up...
So now I am back to 20*180MHz @ 1.2250V, absolutely stable, 50 pass of LinX a couple of times, and many hours of p95... its good.
I think there must be something about uncore, mem. controller and bclk...
200MHz bclk, and no avail... I tried 1.2750V cpu, 1.3750V qpi, still it locked up...

Anyways, whats this special bios? throttling disabled by asus?
and what is is this kind of crossflash thing? doest it help ocing?
