I just installed my new AMD Athlon-XP 3000+ with 333FSB, and everything seems to be working ok, but Windows is showing my prossesor running at 2.4 Ghz, but on my other computer which has an Athlon XP 3200+ with 400 FSB it only runs at 2.19 Ghz!! So what is the deal here?

The 3000+ machine is using PC3200 RAM though, even though it should actually be paired up with PC2700, would the faster RAM be causing the cpu to run faster? Should I be worried, I have some new PC2700 coming in the mail that I will be replacing it with anyways, but I would like to know why my cpu is running at odd speeds.
Thanks for the help!
