1st of all thanks for writing the guide, I found it very useful and I registered just so I can give my thanks and ask for some help
Im currently using :
IP-35 w/ e6550 l719a655.
FSB: 451 (will NOT budge above this)
Ram: Crucial ballistix DDR2 800mhz. Im running 1:1 and with 451 fsb its running at ~900. I tried 5-5-5-15timings w/ 2.2 v
pci-e freq: 100 (like you said)
pci clock sync mode: Im not sure if diff manufactors name it differently but I cant see to find this option in my bios
vcore: 1.35 but I went as high as 1.47
cpu vtt: 1.2000
ICH: 1.5, 1.55, 1.60
NB: 1.25 but went up to 1.53
cpu gtlref: I tried all 4 options 61.5 - 67
All extra power saving options were disabled except cpu temp
Multi set to 7x
Temps are 38 degrees on orthos 20 min blend test using speedfan and coretemp to measure
The problem: I CANNOT go above 451 fsb. Does anyone have any suggestions and if anyone needs more specific specs please let me know
