Can I mix PC-100 and PC-133 memory in the same system?
In almost all cases, the answer is yes. If the system supports 100MHz memory, you can normally use 133MHz memory in it as well, and can even mix the two. However, there would be no advantage gained as the 133MHz memory will only run at the bus speed of 100MHz. Contact your computer manufacturer or motherboard manual for more specifics.
