No idea. According to the mfg it's "automatic", whatever that means, and there is no user interaction possible.


Just found this:

http://www.geardigest.com/2005/08/30/the_turion_64_inside_story/page5.html
It seems its automatic and can be adjusted via "power options properties".


Ah, this might explain what's going on. It seems that the clock cannot or at least does not drop below 800MHz. That's still a whole lot of MHz when doing mundane things such as layout checks. This is what I use my laptop for most. There, I can't see much difference between the old Compaq throttled to 25MHz or so and the new screaming fast laptops. Except that the old Compaq's enclosure crumbled and I can no longer enjoy 6hr runtimes because "modern" design don't deliver that :-(

Why don't they allow a drop to, say, 100MHz or less? Many laptops are routinely used as document displays during meetings. That requires close to zilch in horsepower.

This article suggests that the driver installs automatically with windows update
so you must have it already.


Thanks. According to driver info in their first source link
"12-Feb-02 18:42 5.1.2600.28 32,896 Amdk7.sys"
I must have it. But I'll check.

I bought this laptop on purpose just a month before Vista rolled out, being a bit worried that mfgs might be "discouraged" to sell XP after that. Worries that, as it has turned out, were not unfounded after all.


I also found my problem driver, it was amd dual core optimizer.
Here's a reference to this problem:

It may have been fixed in the mean time, but I'm not going to try, it was
a major headache to get rid of it.


I'd rather stay away from messing with processor drivers. I was hoping there was an easy trick. A hidden routine or something. But if 800MHz is really the minimum for the AMD Turion then there isn't much that can be done anyhow. That's a wee bit disappointing.

Now imagine me the next time when buying a laptop. After garnering disbelief when asking whether an older OS was still available the next question would be "Do you have a model with a slower processor clock rate?".
