CPU fsb and Memory Frequency

I now this isn't really a WinXP question but I was hoping that someone might
help with an answer. Thanks.

I have an older ASUS P4S533 motherboard that supports FSB up to 533 MHz. It
has a P4-2.4 gig processor (533FSB). It has three DRR DIMM banks (that can
hold a max of 3 gigs of memory). The banks are rated for PC2700, 2100, 1600
DIMMS. I have three 512 MB PC2700 memory modules in them for a total of
about 1536 MB.

My question is: Did I put the wrong type of memory in my computer? I
thought I just read that the CPU fsb should match the memory frequency? If
that is true, shouldn’t I have put in PC2100 (266MHz) memory (266 x 2 =
532MHz)?

The Asus MB manual says I can put PC2700 (333MHzs). That seems
contradictory since that would work out to 666MHz. Or the more likely
possibility is that I REALLY DON’T KNOW THE CORRECT RELATIONSHIP BETWEEN CPU
FSB, MB FSB AND MEMORY FREQUENCY.

Anyway, I would really appreciate a quick explanation of this topic and to
know if it was ok to put PC2700 memory in my computer.

Thanks, Mike
 
The faster memory stick cannot run any faster than the bus - so you can use
the memory you have with no problems. There is no reason to swap out for
somethng slower as long as what you're using is working.
