cpu speed problem

[aloip]

hi

my problem is that when im using win xp on my x61 (c2d t7300) the cpu speed is only of 1,2 ghz (performance policy). Ive read in this forum that this happens when the x61 is used with the ac adapter (65 w) but without battery.

Yesterday i installed debian, and here the cpu speed reaches the 2ghz even without the battery, my question is if there is any solution so i can have this performace in vista or xp?

thanks

ps: sorry for my english XD

Welcome to the forum!

You can try disabling Intel Speedstep from within the BIOS. But it´s not good for the battery life if you need to run on battery (though you can re-enable it again when needed).

For full performance in Windows with no battery the normal solution is to use the 90W adapter.

I just tried disabling all power saving features in BIOS which gives me full CPU speed (1,4GHz), instead of the usual 1,2GHz when removing battery and using the 65W adapter...
So, disable SpeedStep, Adaptive Thermal Management: Maximize Performance, CPU Power Management and others: Disabled...

I would not recommend this, but it seems to work

I would think about it from a different perspective. I cannot think of many processes that would make a CPU run at 100% forever. So you really do want adaptive processing as this will let your CPU slow down when not required and keep your laptop cool. It will crank up when needed. Running at full tilt will heat up your computer unnecessarily. .... JDH

I havent tried this, but i could only gain 200 mhz...
I made this question because i have debian and winxp on my x61, the difference between them is that when im using the notebook without the battery in windows the max cpu speed is 1,2ghz, and iin linux is 2 ghz

I agree with you, but i work with matlab and other stuff (simulations) while running office, firefox etc...

thanks
