Will PC100 RAM work for PC66?

[HYMAN]

My computer uses PC66 RAM, but i was wondering if a PC100 or PC133 RAM will also work?
will apriciate any help. thanks.

 

[NaughtyusMaximus]

yes, both PC100, and 133 will work.

 

[andrey]

yes, it sure will. Both PC133 and PC100 are backward compatible with PC66

No actually the memory is too fast for a 66Mhz FSB

j/k <~~~~

Yes it should work -

But I'd like to know: Are the desgns for PC133 and PC100 SDRAMs the same? Do manufactures sort them out like they do with CPUs and find the ones that can tolerate 133 MHz?

I wouldn't be so sure. I tried to put some PC100 memory in my motherboard that only supported PC66 memory about a year and a half ago and the motherboard refused to recognize it. I would turn on the computer and would hear one long, constant beep until I turned it off again. Also when I had the PC100 memory in I could not turn the monitor on, it would just go into power saving mode.
