off the top of my head without researching it
I would think that your chipset and mobo only support a 400mhz FSB
while that 3.2 is probably a 800mhz FSB chip
so that would explain the CPU ghz being cut in half
Just a thought
king smp is correct. According to the specs: "Intel® Pentium® 4 that runs at 2.2 or 2.4 GHz internally and 400 MHz externally, or 2.266, 2.4, 2.53, 2.66, 2.8, or 3.06 GHz internally and 533 MHz externally." The fastest CPU that you can buy is a 3.06 GHz.
Seriously DO NOT pay more than $20 USD with the shipping for that 3.06
I bought two Xeon 3.2 P4 based cpus for $20 with the shipping included on US Ebay
If you have a Microcenter near you they have loose P4 for like $10
also look on Craigslist if available
Changing the CPU would be a good learning experience
and a high end P4 is fine for browsing,cd ripping,office work (MS Word etc)
My wife still uses a P4 2.8 HT for browsing, Bjeweled type games and coupon printing
so it is viable as a light duty computer
but definitley not worth investing serious money in
Btw, I would get a northwood P4 over a Prescott any day. Northwood is comparable in speed to Prescott while using less power, because they made an architectural change that seriously killed Prescott's ability to process efficiently. So even though it was on a 90nm lithography compared to Northwood's 130nm, it was worse speed for the power consumption.
Don't bother spending too much money on one though. They are nothing compared to a low end dual core from AMD or Intel today.
