CPU Multiplier fluctuates on Asus G50VT-X1 Intel p8400

So I still have the good ol' Asus G50vt as pretty much my main laptop

and I noticed something when I'm using cpu-z:

The multiplier keeps changing between 8.5x to 9x and I am a bit annoyed by that because the clock rate fluctuates between 2.7ghz and 2.9ghz (thanks to setFSB).

Is there anyway to keep the multiplier from changing its mind, I'd like to push the cpu a bit more without the fluctuating multiplier?

 

That's intel's dynamic acceleration. Only one core operates at the 9x multiplier, the other keeps the 8.5x. It only happens if there's thermal budget and a single threaded process that needs a slight boost. It's normal, you can't disable it, don't worry about it. Also, your RAM is most likely the limiting factor here, as you're upping the whole FSB. If you grabbed faster RAM perhaps you'd gain another 0.1-0.2 GHz, but nothing significant. You already have the fastest DDR2 available.

 

I see, thanks.

It just makes me uneasy when I see a reading of 2.95 ghz when I'm damn sure that's the threshold of a world of problems. I shouldn't even be pushing it further. Thanks again.

 

Ah don't worry. Sometimes the CPU superclocks itself for a moment (if it's cool enough) and using Everest I've seen momentary speeds well over 3.5GHz. Of course it's one core, for a split second, so nothing useful really. It's the CPU doing its thing, it's a monster and can clock quite high if given the chance. However the RAM isn't so robust so when you up the FSB, it can't keep up as well. You might have some luck in flashing your RAM via SPDtool, I've never used it but you can lower raise the timings so it's running slower (at say, 533MHz instead of 800MHz), and then up the FSB even further. Alternatively, if you want to know how to get your P8400 to 3GHz, I believe it's been done somewhere in this thread (or one like it, I can't find the exact page that says it):

I was also interested in upping my clockspeed for some time and eventually called it quits at 2.7GHz
