Just how backwards compatible is SDRAM? I.e., will 133mhz RAM work ok in a 100mhz FSB system? 75mhz? 66mhz?

PC-133 will work just fine on slower FSBs. It will also worked when mixed with pc-100 as well. Sure, the ram will not be running as fast but you will have no problems putting that pc-133 dimm into that 66mhz system.

just also be aware that there is some newer memory types (eg some 32MX4 256 meg) 133 out there that won't work on any bx motherboard - see http://www.syncmax.com/resultcomp.asp?s=1

Nope! Mosy likely, PC-100 won't be able to hang on FSB133 systems.

What is a "bx" motherboard?

The 'chipset' is the mobo's manager. It handles moving data around among the devices.

Intel i440BX is a very widely used workhorse chipset found on many boards.

Thank you. This forum is great. I learn more "need to know" stuff here than in class.
