1st Overclock but slight problem?

[9761]

Hi,

Im running 2.13 c2d in shuttle sd32g2

just overclocked it by 300x8= 2405.4 but when using cpu-z it keeps changing.

one minute it shows 2405.4 300.7x8 then it changes to 300x6=1804.0

whats wrong, is it surposed to be changing every few sec's?

its the multiplier that keeps changing from 6 to 8 then back to 6, thus reducing the clock speed

Also Vista Ult detects it running at 800Mhz

thanks

see if you can disable 'speedstep' in the bios.

Yeah its speedstep when your cpu is idle it drops to x6 to save power but when you run a cpu intensive task itll jump back up to 8x

I cannot see speedstep in my bios, is it under a different name at all?

thanks

also the shuttle only lets me up the multiplier to 355 and I can only get my c2d 6420 to 337 before it crashes. Any other O/C that will make it go faster?
