M/B：Asus P5K = Vmod Vcore , Vdroop , Vddr , Vmch & Vfsbvtt/RefGtl (not Vpll)
CPU：Intel Q9300 C1 Q803B186 & Q9450 C1
CPU cooling： Thermalright 120 Extreme & Caskade 2 stages R507/R1150 (-107/-109&#176;)
Memory： STT Pc5300 Hynix 
VGA：Sapphire X1900XT & Zotac 8800GTS

With the Learn/jp mod's Vfsbvtt/RefGTL (http://www.xtremesystems.org/forums/...9&postcount=55) , The Q9xx0 Quad gain advantage in fsb max

For Exemple :

Q9450 on Aircooling :

Vfsbvtt/VGtlRef with Vnb at 1.79v :

1.5v Bios = Max 475mhz
1.55v réel = Max 483mhz
1.65v réel = Max 487mhz

Q9300 on Aircooling :

Vfsbvtt/VGtlRef with Vnb at 1.79v :

1.5v Bios = Max 478mhz
1.8v réel = Max 493mhz

I believe that up the Vnb and Vfsbvtt help have a better fsb on Q9xx0 (but I saw no gain on the E8x00 is even worse in aircooling)

Intel Q9450 C1 sous cascade (-108° évapo) , not cold boot

Vcore : 1.6v
Vpll : 1.72v
Vnb : 1.78v
Vfsbvtt/VGtlRef : 1.9v réel

Vfsbvtt/VGtlRef : 1.5v bios = max 500mhz of fsb

Max Screen Cpuz (don't valid at 520mhz)
