i5-2400 overclocked from 3.1 to 3.9 but ?

[duffannvat]

Hello,

I have a z68 motherboard and with asus tool i overclocked my cpu from 3.1 to 3.9 with changing baseclock from 100 to 103 and multiplier to 38.

But when i observe the speed with cpu-z , it nearly all the time shows the speed as 1600 (multiplier 16) only for few seconds in 1-2 mins as 3900 (38 multiplier). Is it because the cpus are not on full load or is there a problem ?

TIA

Disable intel speedstep in your BIOS. The processor is changing it's clock speed automatically based on performance requirements.

Ah thank you ! Where is the setting for turningoff speedsteip in bios ? is there a document or forum post about it

Well I'm not sure exactly because each motherboard manufacturer often has a different BIOS layout. It should be listed in your motherboard manual if you have it, or it would be available online from the manufacturers website. At a guess it would be under advanced settings
