hi there,

today i've managed to set my E8400 @ 4Ghz

this is what i see at the bios

Clock Ratio at x9
Bus speed 445
Memory Multiplier at 2.0
Ram timings at 4-4-4-12
cpu frequency 4.00Ghz (445 x 9)
cpu voltage: 1.25v

but when i run cpu-z 1.52.1

i see...

core speed is 3Ghz
Multiplier x9
Bus Speed 333.4Mhz

am i missing out anything? or it is just displaying wrong numbers?

sorry, i'm pretty new with overclocking

did u save the changes before exiting the bios.

yes

cause after checking the cpu-z

i went back to the bios to double check, it is the same as last config

hav u disabled EIST?

even if he disable it the OC setting should stick.

Added on July 31, 2009, 9:34 pmbtw try increase the processor vcore to 1.4v,loosen the ram timing to CL5,increase the nb voltage to 1.3-1.4v and set the vdimm to 2.1v.

try it and see if the setting stick this time around.

overclock failed already, board return to default status.

this is a factor too.

while some board just hang or beep endlessly.

if the OC fail,the pc should restart a few times before proceeding to boot into OS,and bios evrything reset to default.

need ts to clarify more

hmm.. the pc didn't restart before proceeding

i tried changing back bios using load optimized performance settings

and the fsb goes to 100

becomes 9x100 = 900mhz

but when boot up and check cpu-z, it all normal

may i ask how do i reset?

EDIT: ahh.. it's finally fixed and back to normal.. i removed the battery and it worked... thanks for the help guys
