Intel 2 quad core Q8400 underclocking on strenuous programs.

post #1 of 4
Thread Starter 
Hey, I recently upgraded my E5200 2.22ghz cpu to the Intel 2 quad core Q8400 2.66ghz cpu and everything is running smoothly.

I have however noticed that on certain programs where I would expect the cpu to be clocking at 2.66 ghz it is underclocking significantly I.E 1.11ghz, this occured with World of Warcraft open, however other games it seems to be clocking at 2.66ghz. Is there anyway I can manually set the clock rate for my CPU on individual programs? Or has anyone else experienced this with the same CPU?

Specs:

Mobo: MS-7519 Intel chipset P45/P43/G45/G43
CPU: Intel 2 quad core Q8400 2.66ghz
GPU: Radeon HD 4870 512 MB
Ram: 4gb DDR2

Edit: played around for abit, this only seems to be happening with applications that would usually require optimal cpu preformance, I.E vidya games

It's called SpeedStep, when your computer is not under much load it clocks it down to save power, when your PC needs power it clocks it up to cope with needs. To disable it look in your BIOS for CPU features and disable speedstep, C1E, enhanced hall state .ect

What cooling?
It sounds like a heat issue.

It only shows how old the engine in Wow really is.. CPU doesn't even detect it as serious load... LOL...
