Last week I installed 64-bit Ubuntu 8.04 on a AMD X64 5000+ (2.6 GHz)

was only 1000 MHz. Has anyone else seen this sort of anomoly?
Newer AMD and Intel processors have a frequency scaling feature.
Start a
heavy CPU-intensive task and check again, it should show 2.6GHz. It
scales the CPU clock speed to save power when idling.
Interesting! I was thinking of comparing some task timings with
another box which has an Athlon 2000+ 1.6 GHz CPU, which is the speed
reported, but will check that also. I was actually planning to build
up a box from scratch with an Intel CPU, but came across this one at
Newegg for a price I couldn't pass up (it's refurbished, but other
than the shorter warrantee it looked new).
