CPU-Z CPU clock incorrect?

post #1 of 11
Thread Starter 
So I just got my E2180 yesterday to replace my Pentium 4 and decided to run CPU-Z. I've overclocked it to 2.2GHz, but in CPU-Z it shows the "core speed" as being 1319.08 MHz. Now with my Pentium 4, it shows 3.3GHz as being the speed since I had overclocked it from 3.0GHz to 3.3GHz. Why is CPU-Z showing such a low speed when I'm running my E2180 at 2.2GHz? Here's my CPU-Z validation: http://valid.x86-secret.com/show_oc.php?id=336406

Sorry if the answer if obvious. I'm a bit new to the dual-core scene.

It is a function of your CPU that underclocks for energy saving while the CPU is idle and can be disabled (the function) from your BIOS. Try running a program in the background and the speed will come up to what you have set it at.

Oh! Thanks for the explanation. Just tried it again with Folding@home running and now it reports 2198.6 MHz like it's supposed to. Thanks again!

Just turn off/disable the C1E and EIST in your BIOS and it should read correctly.

Is there any real advantage to me turning this off though? I'd rather save as much power as possible if there's no real advantage to turning it off.

It relates to the energy saving. When C1E and EIST are on, we may encounter stability issue in OC. If you aren't OC, you can let them on. Or, turn them off when you do OC. Once reach certain level, you turn the EIST on and test the system to see it is stable. If it is, then let it on.

It could make the difference between a stable and an unstable oc!

Well I'll just leave it on since my motherboard won't even POST with a bus speed of 225MHz. I know it's the motherboard because it did the same with my Pentium 4 and I've read reviews about it having shaky overclocking. I can't wait to get a new motherboard.

Intel Processors underclock the CPU's multiplier in order to save energy. So, run a CPU intensive application and watch the multiplier raise.

ive heard conflicting reports, but id leave it disbled if OCing as well.

from what i can assume (and im no expert) but if you settings make ur clocks lower when less stress, why OC? unless your using a program/game that is pushing th cpu to its max it wont be running at max clocks right???

Or does it go to max clocks with even small ammounts of stress?

I had my e4300 running 24/7 at 3240 for over a year (average lifespan of pc enthusiast), if im not using pc, i turn it off, thats true power saving mode, but if im using it, i want it to run at max performance, even for forum discussion

my q6600 is alway running at 3150 too........ dont know if ill even make it a year before going for new lineup Qxxxx
