Pentium 4 -- 400 or 533 FSB --- what determines it?

I need to replace my Dimension 4500 motherboard. Dimension 4500's were
sold with either 400 MHz and 533 MHz FSBs. The system ran with 533 MHz
FSB until a lightning strike. The CPU is okay and is for 533 FSB.

Does the motherboard have to be matched to 533 FSB?

Or is the FSB determined completely by the CPU?
.
