I have a BIOSTAR P4M80-M4 and a Celeron 310 processor.the board supports pc3200 ram.the processor runs at 533.can i use pc3200 ram with this processor? thanks.

Yes you can, but the RAM will
just run at 533(PC2100). I'm pretty sure you can run the RAM asynchronously
with that mobo, so i would try. The setting in the BIOS would be 400. If that
isn't an option, but there's a 333 setting, use it. The extra bandwidth will speed things up a little.I set up a Celly 340 for my dad, in the Mach Speed
version of your board, and after setting the RAM to 400, it definetely made it
"snappier".  GL
