Envy 14 - CPU i5 450M Turbo Mode

Hi,

I was wondering if anyone were able to turn on/off the turbo mode.

I'm having a major issue when playing games with my Envy 14, every game I test, I always get annoying spikes, everything pause for like ~0.5 sec, I tried and test everything under my knowledge, GPU/CPU/Laptop temp., HDD features APM/AAM, graphic settings, and tested my games with ATI/Intel GPU.

And sometimes I get these spikes when I'm browsing or listening to music.

The only thing I couldn't test was the Turbo mode, I heard couple of people saying that whenever the Turbo mode goes on and off, it give spikes.

Any thoughts or solution for the spikes issue?

EDIT:
Tested the priorities of applications as well.

Thank you

 

this happens while using battery power or outlet? Or both?

 

Turbo should not be causing spikes, the cpu scales up and down constantly, just because it is going above intels recommended clock speed doesn't mean it should hold anything up, this is bios level stuff for the most part.

What speed harddrive do you have, the 7200 or the 5400? Has it been defragged (not that it would need it, very unlikely scenario, just always a good idea to do just in case).

Have you updated to the last drives, audio etc?

 

I'm getting the spikes in both battery and outlet.

HDD is 7200rpm, Toshiba HDD if I'm not mistaken.

I've updated every driver I've got. I even done a clean installation and updated everything as well.

I'm using an application called quiteHDD, it stops APM "Advance Power Management", I've read some post about someone having same problem and he yours solved, I've tried that but no use.

 

Shameful bump.

 

I would run "HWMonitor" while you use your laptop, and look what is the highest temperature of your components.

If a heatsink is not well set on its chip, you may get temperature spikes that throttle the chip thus creating the "spikes".

Yet that may not be your problem, it's worth checking out.
