    What's the best RAM configuration for a MacPro 2.66 ( the new one )

    what i mean is, is it better to have pairs of same kind or size .....etc...?


    i would like to have in total around 8 GB of RAM ..

    is that a decent amount for heavy photoshop and video work...?

    8GB is plenty of RAM. If you're configuring from scratch, the optimum arrangement would be 2 pairs of 2 GB sticks....The first pair (i.e. 4 GB) on the upper riser in slots 1 and 2, and the same arrangement on the bottom riser.

    The ram gets split evenly over each core, so you want it to be evenly into 4 (2GBx4 or 1GBx8) so the computers doesn't have to add a little from this and a little from this. I'd say that 2GBx4 is better because the computer doesn't have to divide the data more than it needs too, but that's just a guess. 2GBx4 also leaves more slots open for later upgrades.

    I do heavy photoshop and some video (though not HD work) and run 8 gigs. I think it's enough, though if you are running something else like parallels that is a memory hog then a bit more might be nice.

    If you can do it then 4 x 2 gb is perfect! As noted above, split them into 2 into each riser in slot a.

    Cheers!

    How about 9gb??

    I upgraded my 1gb Mac Pro with 4 2g sticks populated as everyone says. I moved my original 1gb (2x512) to the 2nd location on riser a. Everything has been working ok. I was just wondering if having that oddball 1gb on 1 riser would slow things down or not. I run Fusion with at least 1 full time xp machine running (with 3gb dedicated to it).

    Thanks!

    Good question. 9 Gigs seems a bit odd, but it´s probably okay since you have the one Gig paired (2x512).

    What about 6 Gigs total? Is adding 2x2GB sticks to the 2x1GB sticks a bad idea? Should they all be the same capacity? Or is it alright as long as there are pairs?
