Re: why cpu MHz in /proc/cpuinfo different from model spec?

I think the machines are mostly running CentOS. Has the evil
Microsoft/Intel conspiracy extended to engulf CentOS as well, so that
it's now deliberately reporting AMD chips as slower? :) Or is there a
simpler explanation.

I'd like to know what it is, too. On one of my AMD 64 X2 systems
Solaris 10 reports the CPUs' GHz correctly but Fedora 9 does not.

AMD has some tools that completely characterize their CPUs; their
CPUInfo_2.2.0 is only for Windows systems but they do have a
linux_frequency_driver-2.10.0.tar.bz2 and a bunch of RPMs for
RHEL4, SLES9 and SUSE100 on their website (under Support IIRC).
