Can someone tell me if I can use PC133 memory on my Asus CUBX motherboard with a coppermine Intel 800/100 CPU. I know that I can set the bus speed on the motherboard to 133 but the cpu is 800/100. Do I need the 800/133 CPU to use the 133 memory.
Generally speaking, the memories rating (133 Mhz) is a suggestion as to how fast you can push it. You can run it at 100 if you want.
I have two 128M DIMMS: one PC-100 and one PC-133, both running at 118MHz.
Nope. They are separate things, though a higher memory frequency results in better performance.
