PC133 and PC100 compatibility...

[LimeLite]

I think I've heard that you can use slower RAM in faster RAM slots, but my question is:
If I had some PC133 RAM, could I put it in a computer that used PC100? What would happen?

The PC 133 ram would throttle down to the speed of the bus, so the ram would run at PC 100 speeds if you put in PC 133 ram.

he is correct. you can make fast ram slower, but you cant make slow ram faster.
