Can I use PC133 memory with PC100 memory in the same computer?

[dodo]

I have 128M PC100 RAM and I want to upgrade my computer to more memory. I saw now there are PC133 everywhere especially for the RAM chips larger than 256M. So can I just bought one PC133 memory and use it together with my PC100 memory? Thanks a lot.

No problem
In fact you usually can run your PC100 in a PC133 machine if its good quality.

yeah you can but i would recommend you run your memory at 100mhz. Also, put the PC133 module in the first dimm slot and the PC100 module in the second slot.

Thanks for the infor. May I know how to tell which one is the first slot and which one is the second?
