lol kk. No raise le, i din touch those other than my proc vcore and ram vdimm.

hahahaha.
now that is much better.

how high have u go with ur proc??

hi guys, can help me with OC my e8400 C0 stepping to 4.0Ghz or perhaps to 4.5ghz ?

when i oc my e8400 to 4.0ghz i got a blue screen after log in to windows...>.<

now i can only OCing to 3.8, by the way i passed the prime/intel burn test in 3.8ghz.

so any1 can help me state my prob? kinda newbie to oc here? might be insufficient wattage? or ram size/speed ?

can check my sig for spec tho.
thx

nothing wrong with ur ram,mobo or psu there.

mind telling me what vcore setting u using now??

Just 4ghz then i stop edi hehe. The bios abit stupid, if i oc wrong, then have to clear cmos then everything need to set again. Cannot like save profile one while gigabyte can..

My current setting in bios for oc 3.8Ghz

Fsb: 424 ( i guess )
Multiplier : 9
Dram manually: 5-5-5-15

CPU Voltage : 1.34.... ( cpu voltage = vcore right? )
NB voltage: Auto
Rad voltage : 2.0

others setting i just put auto

can tell me whats wrong with my setting

ok.

when i oc my proc to 4ghz i put my

vcore to 1.37v
northbridge to 1.33v
southbridge to 1.55v

try it and may i know what stepping is ur proc??

C0 stepping

Hilmi OC using 450X9 rite? I OCed mine 500X8 and it needs higher vcore...maybe my proc...but vSB 1.48 and didn't touch the NB voltage...

bro i tried to change my setting as the setting u stated above but the prob is my southbridge max is 1.40v only ( so i changed it to 1.4 )

after i changed it....can log in to windows, can browse internet, but when i try to run intel burn test/ prime........the program will got an error saying that the program has "stopped working"..

so i guess still got prob.....

try pump up d Vnb

play around w/ vtt n gtl ref

and i also have a question here.

does i need to change the cpu vtt setting??
what does it do exactly???
i search around the web but cant find what does it mean exactly.....

Bro, C0 need more vcore to be stable @ 4Ghz...not like E0...try to raise the vcore...

try to up the vcore bit by bit. i am using E8400 (c0 stepping) and asus p5q deluxe; 24-7 @ 4.0GHz. i do enable load line calibration, and under load i need 1.272v to be able to pass 6-hours of occt's blend test. the other voltage are as follow:
vNB - 1.20v
vFSB - 1.10v
vPLL - 1.50v
vDDR - 1.90v - depends on the ram (i am using ocz flex 9600)

if i were in ur shoes
i wouldnt start playing wit the Vsb 1st
i'd prolly focus on Vnb and Vtt
then fine tweak using gtl

@zuhair
1000 cl5 @ 2.1vdim?
wow...dats high
would u like to share some of ur flex results?
i heard the older version can do miracle

That's a low vcore u got there...1.272v in bios is it?

whats ur vcore when running 500x8????

1.4v man...

still ok what.
im using 1.37 on that speed.plus mine is e0 so i should be crying

1.6v to run 500*8 here
