    okay, i'm new here so go easy on me... haha.

    alright, i've got an iMac from late 2006. and i'm trying to upgrade the ram..

    here's the specs...

    iMac intel
    1GB ram
    250 gig

    so on the box it says upgradeable to 3 GB of ram... but the computer has two slots... which currently have a 512MB card in each of them. so my question is how do i install three gigs of ram? a 1GB card and a 2GB card? this doesn't seem to make sense, because i thought you were always supposed to keep them balanced.... so should i just install 2 - 2GB cards... for a total of 4 gigs... even though the computer will only used 3 gigs?

    that's what i sorta got from this page...

    any help with this would be great... as i've been searching the net for hours... without a definite answer.

    Get 2x2GB. That will enable dual-channeling which should boost ~5-10%

    Yes, exactly. Take out the 2ea 512M modules and sell em on eBay and get a couple of 2G modules. You'll only be able to see/use 3G but that should give a good performance boost
