How will i know if my SDRAM is PC 66 or PC100? my mobo has 4 slots, 2 SIMMS AND 2 DIMMS. im planning to use my DIMM but i got a PC100 SDRAM.
What will happen if i use a PC100 on PC66 RAM?

thanks.

Nothing, on most motherboards using higher rated (PC100 in a baord that came with PC66) is fine, running the other way around though (PC66 in a board that needs PC100) will cause problems.

my mobo is old and running at P1-200. can i see it in my mobo manual? but im afraid i lost it already.

anyway.. thanks mjc...

A pentium 200 will have a 66mhz fsb...so if you have pc100 ram, it should work fine...
