    dual-channel (and?)/or more memory?

    i have a dell xps m140 coming in the mail. needless to say, i will not be using this machine for gaming. it will be for word-processing, email, excel, statistical analysis, photo-viewing/basic manipulation, and playing multimedia. i would like to have a pretty fast speed for these tasks. the machine will ship with 2 dimms of 256 mb ddr2 533 mhz. i would like to upgrade the ram, and i understand that the m140 is dual-channel capable.

    should i just replace one of the 256 dimms with a 512? this will negate the dual-channel feature, right? but will i notice a big difference in performance between single-channel 768 and dual channel 1 gb?

    otherwise, if 1 gig is recommended, it seems like i should go with 2 x 512 for dual-channel, right? i would think i won't be needing 2 gigs anytime soon . . .

    so getting single-channel 768 will cost $45, dual-channel 1 gig will cost $90. what would you do?

    thanks.

    Dual channel is not going to give you a 50% increase in speed. (More like 5% which is nothing compared to the performance increase of doubling the RAM) The more RAM you have the better, whether it is dual channel or not. I would personally go for the 1 stick of 1GB because if you ever want to upgrade later, you'll have to get rid of either a 256 or 512 anyway. But don't worry about dual channel, just opt for as much RAM as you can get.

    oh yeah, i forgot to list that as the third option: 1.2 gig of single-channel for $90. so your advice would be to go with that. no instability issues with a 1 gig paired with a 256 mb, are there?

    regardless, 5% increase does not seem like much of a performance boost. thanks.

    any other input out there?

    no instability issues, just make sure that you have the correct type of RAM, eg. DDR vs DDR2 (they aren't interchangeable), and if you have 400MHz RAM in there right now and buy 533MHz RAM, it will downclock to 400MHz but it's not a big deal if you don't game, but it's kind of a waste.
