    [Ixtk/Ocm] Asus P5K Broke WR Q9300/Q9450 C1

    ::|:: Q9300 & Q9450 C1 OEM ::|::


    Click the thumbnail to view full-size image




    Code:
    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°)
Memory： STT Pc5300 Hynix 
VGA：Sapphire X1900XT & Zotac 8800GTS 
HDD： Hitachi 250go 8mo Sata
Power Supply：OCZ ProXstream 1000w
OS：Windows  XP PNX & 2K3



    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)

    Intel Q9300 C1 under cascade (-109° évapo) , cold boot at -70°

    Vcore : 1.6v
    Vpll : 1.72v
    Vnb : 2.05v
    Vfsbvtt/VGtlRef : 2.15v réel

    Vfsbvtt/VGtlRef : 1.8v réel = max 513mhz of fsb


    Max Screen Cpuz (don't valid at 524mhz)
