What's the fastest P4 I can get to use with PC2100 memory?

I'm thinking of using 4 512 meg sticks of PC2100 memory I have in a new P4 system. I've never built a P4 system yet -- I only have Athlon XP based systems -- so I'm kind of confused about the P4's front side bus and memory speeds.

It seems like the fastest P4 cpu for me is one that uses a 533 Mhz front side bus, right? That's because the P4 bus is quad speed so with my 133 Mhz memory, I would need a front side bus with 4 x 133 Mhz = 533 Mhz.

It depends if you want to run the memory 1:1. If you motherboard allows it you could get by running a different ratio until you get faster memory. R

You cna use any P4, provided the motherboard supports different speeds for the RAM and FSB. However, you'd get much,MUCH better performance from an Athlon with that memory. A P4 w/o at least PC2700 on the 845PE is a dog.
