View Full Version : Is PC133 suitable for Satellite Pro 4600 memory upgrade?

Greetings to all,

I'm looking for an extra 256mb memory module for my Toshiba Satellite Pro 4600. The specs say a PC100 memory module is required, but I was wondering whether PC133 modules would work as well. If so, are there any problems with mixing modules (PC100 and PC133) ?

Thank you for your attention.

I can't say it for sure, but I've heard about notebooks that originally have PC100 memory and also work with PC133, but this is an exception. Mixing the modules normally doesn't work.

I think you should give it a try. In the worst case you will get an error message and have to bring back the memory to the shop.

According to the information on the very useful memory module website, it should be possible to use the 144-Pin PC133 SODIMM modules.

I have found this info on this site:

Furthermore I wouldn’t recommend mixing the different modules. In my knowledge the lower speed module will decreases the memory performance. Both modules will work with the performance of the lower module.
