    hi!

    I'm thinking of bumping up my total memory to 3GB maximum for the particular 17-inch 2.33GHz model from the 2GB factory standard, since I do have to fire up Windows several times a week for a hardware design software and 1GB of RAM is now being allocated to it.

    However I often hear people around say that having two different memories in the same machine would compromise stability, therefore I wonder to what extent that claim is true and whether it's really worth for me replacing a 1GB RAM for new 2GB unit?

    thanks a lot!

    I've read several posts that indicate that you shouldn't have a stability problem, but you will lose the "dual channel" ability due to memory modules of different sizes. I don't really know what the implications behind losing that ability are, except I would guess maybe a loss of speed?

    it is best to have the same speed and quality of memory installed . You can test the new ram with tech tool to see if it matches up. Being that you have to put in a 2gb and a 1 gb stick there is no way to get a "pair" that is perfectly matched

    Or you could go 4GB stuck in. Your 2.33 (I had the exact same model, only 15") can read up to 3.3GB
