CPU multiplier (jumper) lock?
Hello!
My question might sound stupid, but believe me, it's not.:emotion-1: So, I have a Precision M90 laptop, and the thing that keeps picking on me is the "jumping" FSB multiplier.
Ok, when I'm on battery, I don't mind, it better decide the power consumption than me. But when I'm changing to AC, it also wants to save energy. However, as the machine has a 130W AC adapter, it still consumes less, than 40% of power than my PC does.
Also, it sometimes decides badly to keep the CPU at 1.3 GHz instead of 1.83, especially in audio production software. If I set the buffer to about 30-40 ms, the sound starts lagging very bad, even in very low CPU intense parts of a project. My desktop PC doesn't do that, however, all of it's specs are lower than the M90's (1.666 GHZ Athlon 2000+ XP, ABIT NF-7 onboard nforce audio), and that performs way better, even can reach 17-18 ms without underrunning the buffer.
So, in a nutshell, how can I lock the CPU multiplier to 12x? (FSB: 166 MHz, dunno if it matters or not :emotion-2:) It would be a bliss compared to now :emotion-1:

I understand, you have the point.
Still, the question remains, if there are any ways to do the trick, as it would be very important. Thinking about when I'm playing a game, it's always on full load, and should be also when I'm creating music. The fans are great, and keep the cpu at around 40-50 °C when the system's fully loaded over a long time.

Notebook CPUs are designed to dynamically adjust the CPU speed according to load. You SHOULD NOT lock the speed to maximum - the system is not engineered to handle the stress (heat produced) by running the CPU flat-out all the time.
Just like your car's engine running at redline, the life of the components inside a notebook will be drastically shortened by running at full speed all the time.

That's exactly what I wanted. Thank you!
Btw, I don't know, why starting clockgen makes everest generate 50% CPU usage:emotion-2:

Go into the power management settings in the control panel and set the system to "always on" or home/office desktop.
