My CPU is a 3.20 GHz, but my CPU Speed is only 1577.5!

Sorry, I'm just a high school chick and not a computer know-it-all!
I just installed a new CPU on my computer.  It's a 3.2 GHz Pentium 4 CPU.  It replaced a 2.60 GHz P4.  Yet, when I ran SystemSpec (www.alexnolan.net), it shows that the CPU is indeed a 3.202, but the CPU speed is only 1577.5 Mhz.

What is wrong?  What do I need to tweak?  Hyperthreading is enabled on the BIOS. . .

Thanks, guys!

have you tried CPU-Z? Anyway, I think that possibly your BIOS has set the wrong "Front Side Bus" speed. The speed you quote is suspiciously close to half the the proper speed... Did you go into the BIOS after installing the new CPU?

It could be that your 2.6 GHz part had an FSB speed of 100 MHz, whereas the 3.0 part would need a 200 MHz setting.
