There are several types of processors now. They can run with
FSB400, FSB533, and FSB800. Your motherboard accepts FSB400 processors,
so if you use a FSB800 processor, it will run at 1/2 speed. A
FSB800 processor would be referred to as a 2.4C, since it is the
third type. You may want to contact your vendor and get a different
model than the one you have currently.
A FSB400 should run no problem at default settings.
A FSB533 would need the CPU External Freq set to 133.
A FSB800 will run at half speed, but if you set the CPU External Freq
to 133, you'll get a little more speed out of it, but not the full
rating.
The multiplier on these processors is locked and that is why CPU
External Freq is the only adjustment.
From the processorfinder.intel.com website, these are all the
Pentium 4 processors with a core speed of 2.4GHz.
