Memory FAQ Topics
||Can I use PC133 or PC100 SDRAM in my PC that has a 66MHz front side bus?
||All SDRAM is backward compatible and can run at any bus speed slower than it is rated to run.
For example, a PC133 SDRAM DIMM is capable of running at 133MHz, 100MHz, and 66MHz. There are a few older motherboards that require 66MHz SDRAM and that will not accept PC100 or PC133 SDRAM, but they are the exceptions to the rule.
Keep in mind that your memory run will only run as fast as the slowest component installed. If you install PC100 memory on a system with a 66MHz front side bus, the memory will only run at 66MHz.
