powernow on amd64

I'd say enable CnQ and you might not even know your system is on :-) I have
it running (3200 Winchester on Asus A8V, Antec 2650BWE with a Sonata PSU)
and the first couple of days I had to look to see if it was on because I
accidentally turned it off twice when I'd gone away for a few minutes,
forgot I'd left it on. Compared to my previous system (same case, PSU but
P4P800 with a 2.6C P4, stock cooler with Asus Q-Fan at lowest setting) it is
virtually silent. I run about 70% of the time at 1000, the response time to
full speed when it's needed it almost instantaneous. It's a heck of a lot
faster to respond than SpeedStep on my laptop at work. I'm impressed, it's a
good feature. Heat kills semi-conductors so the less heat they endure the
longer they last.

I agree. I have yet tofind a reason to not have it enabled. The specifics
are on AMD's site on the response time but I don't remember offhand how fast
it was. It was something to the effect of as often as 30 times per SECOND
though :D. Cool'n'Quiet and PowerNow! are both very efficient and
unnoticeable in application.
 
Well, alrighty, you guys did a good job of convincing me to give it a
shot. I'll play with it tonight... especially since WinXP 64-bit may be
coming out today ;)

Hmmm... okie, I've enabled Cool'N'Quiet in the BIOS but it doesn't seem
there has been an effect on my CPU temperature, it's remained the same.
Do I need to load the Cool'N'Quiet software as well? I didn't because
it says it's only for Windows 2000 and below...

And it's still not working?

I don't know if it is or not. I don't really have any proof of it
working one way or the other because there was no software... it was
just a processor driver for WinXP. My temperature on the CPU didn't
lower (or raise, for that matter) and I don't seem to have any software
loaded that can tell me what it's doing.

That page does not have a Cool'N'Quiet software for Windows XP, only
Windows 2000 and below, like I said. I have the AMD processor driver
from that page loaded.

You should read the page a little better:

"AMD Cool'n'Quiet / PowerNow! Dashboard Demo - This utility displays a graphical dashboard
showing the current voltage, frequency, power savings, and utilization of a processor
running on a Cool'n'Quiet or PowerNow! enabled system. The utility can be run on Windows
2000, Windows XP, and 64-bit Windows.
See the release notes for more detail"

Download CPU-Z http://www.cpuid.com/cpuz.php#download. What does it say for
Core Speed on the first page?

Go to Start> Control Panel> Power Options and under Power Schemes select
Minimal Power Management.

All that does is show a graphical display that tells me the CPU is
running at 100% and all voltages are normal, etc. I've already looked
at that one too.

Aha, that might have done the trick. Now CPUID says I'm running at half
the core speed as earlier...

Wow, now that's a difference... temperature went from 111'F to 75-77'F.

Thanks for all the help, guys - I'll run with this for a bit ;)

Cool. Just out of interest what's your model of Athlon 64?
