    Hey

    I want to get some more RAM for my iMac G5, it takes PC3200 RAM and I wondered what amount was the best to get, I currently have 1GB of RAM, with 1 crucial and 1 apple stick, should I replace the crucial stick and replace it with a 1GB stick, or would it be better (in terms of performance) to get 2GB, whats the difference over 1.5GB in terms of speed as it says G5's work better with Paired RAM (at least on Crucials website)?

    Also for any beifits of pair RAM do i need to buy a 2*1GB "kit" or will 2 individual 1GB sticks be just as good?

    I need more RAM as generally I only have about 100MB free, I have about 1000 page outs today even though I have been using my machine lightly, so I'm pretty sure more RAM.

    Well for the iMac G5 the only way to get paired sticks is with the setup you have now(2 x 512MB sticks) or with two paired 1GB sticks. The paired Ram applies mostly to the PM G5's, Intel Mac Mini's, and possibly the MacBook Pros. I'm not sure which iMac G5 model you have, but I'm assuming it's either a Rev A or B since you are talking about swapping out the chips from both slots. I would get the most RAM possible which is 2 X 1GB Sticks. If you have the iSight model then you can only upgrade the second Ram slot.

    Thanks for your quick response!

    Yeah my iMac G5 is rev B...

    Would it be much worse to go for 1x 1GB and 1x 512MB, than 2x1GB?

    I have a Rev A G5 iMac with the 1 GB / 512 MB setup you mentioned & I have been very happy with the performance thus far.
    However, Apple does recommend matching sticks & here's their explanation:

    I think if you can make it happen, you'd be better off with 2 x 1GB.
