Hey, I learned something from that.

From now on I'll have to add "are you undervolting?" to my repertoire of First Exclude The Obvious Hardware Abuse questions

Yeah, but even before using RMClock, I still experience the mouse problem.

And I'm wondering why in my Vista computers, that doesn't happen?

What would be the solution to get rid of the mouse movement CPU usage?

And I will be losing the ability to undervolt? It's just that it lowers temps by a notch

Put it back on and see what happens. If the high mouse proc util returns... it's obvious.

It doesn't happen on my Win7 machines either, but then that doesn't really matter. It would certainly be wrong to link the colour of the case to whether the problem occurs or not ("mine is silver, yours is beige, therefore that must be the difference"), so it's best not to speculate about why something does or doesn't occur under a completely different installation.

Given that your "mouse" utilisation is now averaging under 10%, I'd say you already found your solution. Remember that it used to be 30%.

Setting the thing to run at 233MHz would also lower temps by several notches. It is, of course, up to you how much you want to experiment with the hardware in order to eke out some supposed temperature or battery life improvements. Personally, I advise people to run their hardware within its design spec.

Ok I still want to reformat this and see if the problem goes away. Thank you very much!

If I understand correctly, what you're saying is that you're going to attempt to get RMclock/undervolting happening while at the same time keeping the "mouse" type of processor utilisation at 10% or less?

All the best, and thanks for an interesting journey

Nah. I can do without the undervolting but I really don't want the "mouse" utilization to take a considerable chunk for the CPU usage.

Why do you think the mouse movement does make the explorer.exe make CPU usage up?

You're confusing me now.

The latest xperf run shows your explorer.exe utilisation at or slightly below 10% during a very sustained mouse wriggling session. Given that it came down from ~30% when you removed RMclock/undervolting, and that stopping the desktop animation also removed the "10sec" spike", what is it that you're trying to achieve now? (Substantially) Less than 10% during sustained mouse movement? That may not be practical, given the finite nature of the hardware resources.

By lowering mouse DPI it's conceivable that you might squeeze a few more percentage points out of it, but that's really too whacky for most purposes.

EDIT: Hold on a tick.... I just realised something

Ok, lol. Well my aim now is just to be similar to your machines where the mouse movement DOESN'T add anything to the CPU usage.

Mouse movement always adds to CPU usage...how else do you think the computer will know where the mouse is if the CPU doesn't calculate it?

Btw you do not need to undervolt your processor. Windows is able to that by using Intel's Speedstep. Go into Power Management > Advance.

Yes, but just about 1%. My friend has Windows 7 also, he has three/four programs opened and his CPU usage is 0%.
