"ASUS P5Q Deluxe discussion".

[mac_69]

Processor Q9450
RAM Corsair Dominator 8500 4x2GB
Asus P5Q Deluxe
Vista x64

My original core vis is 1.15 and 1.25 at x6 and x8, according to Everest/CPUz

Rather than clog up the board, I'll edit this post for my current overclock settings. I had some problems trying lower settings and bioses, and this is what I came up with

BIOS 803
(tested stable prime95 6hrs large & then 8hrs small, no issues)


*Edited 15th OCtober for 1406 bios and new settings gleaned from the thread - thanks all!

*now using 2201, no problems

and that's it, 3.6 stable

Air cooling, thermalright IFX-14 (without the backplate cooler as it was shorting on the P182 case). I a Noctua on IFX and inplace of case fans

Real temp under prime showing ~61deg C on one core rest ~56deg C

When I tried >3.6 it gets unstable and so after reading around, happy with settling for 3.6 with speedstep for 24/7
Stability is important to me - I upped the vcore from 1.33 to keep stable. Temps are okay.

Thanks to Luicis et al with the Q9450/P5Q combination on this thread and the other under Q9450
