CPU Core Speed Going Up and Down

Hey Everyone,
I have a Q6600 that I've been slowly overclocking. The only weird thing that I'm running into is that in CPU-Z my core speed goes from 2.6MHz to 1.7MHz every one to three seconds. Is this normal or does my CPU really drop down that far? I've watched CPU-Z while running a game and it does the same thing. Also if this isn't normal do you have any suggestions on how to get it working the way it should.

Thanks
Nick
 
wats the serial numer on it? if the last 5 letters are SLACR, then it has G0 stepping, and i would of thought that was the problem
 
I have the same problem, i tried to disable the eist but nothing happen.
I think its the C1E function, but not certain yet.
Beside i think its ok that way, it will reduce the heat and power consumpsion for a while.
If u trigger it (game, scan virus, etc) the clock will max out just like u use the eist, trust me.
 
C1e and EIST are safe to run when stock, however it can lower the voltage, thus compromising an overclock, if one is applied. It's generally advised to disable both when overclocking.
 
I disabled, saved settings, and then restarted again to make sure the disable stuck and it did but it still goes up and down. I guess I'll just have to deal with it unless I find something else that could be making this happen. And to the poster above I have a B3 stepping. Later today I'll take a picture of my BIOS screen and maybe someone will find something that is wrong with the settings.

Thanks for everyone's help so far!
 
Btw hermeslyre, do you know the different between eist and c1e? All i know the function is the same.
I oc my processor with c1e on and eist off is it ok with that setting?

C1e is a CPU halt function, reducing multiplier and voltage only when a halt state is required. EIST performs the same function but doing it whenever the CPU is Idle, So they are pretty much the same thing, and it is ok to have them off, doesn't hurt anything, on the contrary, as I saud above it helps to stablize an overclock.
 
When at stock they also help to reduce power consumption and lower the temps. But turn them off if you're going to OC.
