    I have a late model (2006) 24" iMac with 2 GB of ram... I want to up it to the max, which is 3GB...

    Now, I have been reading that even though the iMac only can use 3GB, its better to install equal pairs... which would be 4GB (2 - 2GB sticks).

    Can anyone actually confirm that it does make a performance difference running pairs, even though 1GB will go unused?

    Thanks,

    Scott

    Real world performance from 128-bit addressing is negligible; however, you may benefit from the extra 300MB as your iMac is able to address 3.3GB, especially if you regularly max it out.

    Makes sense... Plus, newegg had a good price right now on 2GB Crucial.

    Just ordered 2... anyone want 2 - 1GB sticks?

    They are on eBay
