Can I replace PC100 Memory chip with PC133 chip?

  pcbobby 13:50 21 Sep 06

I have bought Win XP Home edition software to install on my reserve PC. The machine is a Compaq Desk Pro. Pentium 3/500 MHz.
I removed the memory stick, PC100 –222- 620. CL2 128MB, to increase the RAM on my everyday PC.

My question is, as my intention is a clean install XP on my reserve machine – can I now insert a 256MB, PC133 memory stick in my old PC? (As PC133 memory sticks appear to be cheaper) Or must it still be a PC100?

Thank you for any advice.

As far as I can recall you can use faster memory, but it will/may only work at the bus speed available i.e. PC100 in your case if it is backwards compatible.

Usually it's just plug in and run. It will run as Stuartli says.

Hi Stuartli.

Thank you for the feed back.
Not sure of the model of Desk Pro. I did check the Compaq www, but there were so many models of DeskPRo, I could not equate it with my old Pc.

I shall go with your advice re PC100.

Kind regards.
