Q6600 3.6GHz OC problem

[michaelmk86]

Im running a Q6600 on an ASUS P5K-VM. From everything I have been seeing 3.6ghz should be completely possible with this motherboard. Now I am ruing 3.2GHz 400x8 AUTO (prime95 stable) but if I OC to 3.6GHz 400x9 AUTO windows don’t even start. I have tried to do this manual 3.6GHz 400x9 v1.46 and still windows don’t start.
Just looking for some feedback on what Vcore and what settings I need to use in order achieve 3.6 prime95 stable.

more info needed...how are your temp at 3.2, your cooler, case other spec like RAM...generally leaving parameters in bios on auto is not good choice

Temps are not a problem. Ram DD2 800.

I didn’t change the timings on ram, the ratio is 1:1. I try 400x9 v1.537 and windows start normal but in prime95 fails after 30sec approximately also i notice a big vdroop cpu-z idle is v1.46 and load (prime95) v1.32.
