my gigabyte GA-K8VT800M unfortunately does not seem to support
cool'n'quiet. so, in order to get my computer to be a bit more quiet,
I would love to reduce its clockspeed---of course, not supported in
the BIOS, either.

are there any windows or linux utilities that would allow me to
throttle the athlon64?

sincerely, /iaw

Just in case you over looked something.....

AMD Athlon™ 64 Processor Utilities and Updates

AMD also has a page with a bunch of links to Linux and Windows 64
drivers and stuff but I can't seem to find it.

Cheers,

I don't think you really want to throttle, just reduce
power consumption at idle.

AFAIK, all AMD cpus since the K5 have lower power consumption
at the `HLT` instruction. Modern OSes since about OS/2
(but notabily not MS-Win9*) idle at HLT.

The "problem" with AMD K7+ chips is that there's an obscure
setting that the Northbridge has to be enabled to really
reduce the power consumption. A bit has to be set in the
PCI config registers.

Different chipsets have different locations for this bit.
There are various untilities to do it. I use `setpci`
on Linux. I presume there are MS-Windows utilites too.

hi robert: not the same thing. apparently, more recent kernels have
the frequency stuff pre-built in, but it needs to be enabled.
