Intel e8400 clock problem

Last response: in CPUs

My CPU is Intel e8400 @ 3.0 Ghz and my motherboard is Gigabyte 965P-S3

My problem is that all the diagnostic tools I have used have shown me that my CPU was running at 2,4 Ghz instead of 3.0 Ghz.

I have never tried to overclock my CPU so I don't know what's going on with it.

Can anybody help me?

965 is not a good chipset

what diagnostic tools? CPU-Z

the underclock is probably because ur keeping the CPU still if u move a window really fast or start a task it will go back to 3 ghz\

this is normal, it is called speedstep, it is for conserving power, ther is noting wrong with ur processor

Your motherboard only supports a 1066MHz FSB, the e8400 requires a 1333MHz FSB to run at 3GHz. You can either OC your FSB, or get a newer motherboard which supports 1333MHz FSB CPUs.

the proc automatically down clocks if the FSB is lower on the mobo, and like i said it is because the proc has speedstep, it will be lower if u don't do anything while testing it.

Posting a screenshot of CPUz may help people to point you in the right direction because if your board is a revision 3.3 it can support 1333 FSB but a rev 1.0 might not.

Ok, so how can I do it manually?
But I remember my CPU running at 3.0 ...

In BIOS > MB Intelligent Tweaker(M.I.T.) > CPU Host Frequency (Mhz) > If you use a 1333 MHz FSB processor, set "CPU Host Frequency" to 333 MHz


Ok. And the strangest thing - I've turned the power supply off for a while, and then I've turned it on. And it seems that the problem is solved.

- as You can see.......

Bonus!!, it could just be a buggy BIOS/CMOS issue. You could re flash the BIOS and do a CMOS reset it you wish but I would change the mobo battery first.
