CPU speed in windows xp

I just bought a compaq computer with an amd athlon 64 3700+ when I look in system properties sometimes it reports cpu speed as 983mhz and 1.77ghz and 2.2ghz ( it's mean't to be 2.2ghz).

why does this happen?

I looked in BIOS as it shows up correctly there.

Thankyou

Becasue they have activated "Cool and Quiet" which throttles the CPU back to a lower speed when the full power isn't required.

Speed stepping, So it only goes when you put your foot down

ok, so it's normal and only goes to 2.2ghz when it's needed.

Thnkyou very much.
