    I think this has been discussed, but I did not come away with a clear cut answer, so here goes.

    Compare a nForce2 mobo with (2) Crucial 256 MB sticks (in Dual Channel mode)

    versus

    An nForce2 mobo with (2) Crucial 256 MB sticks (in Dual Channel mode) AND (1) more 256 MB stick.

    Assuming all ram is same speed, size, brand, timings, etc.

    First Question: Is the effectivness of the Dual Channel lost? If it is not lost completely, how is it affected?

    with the 3rd stick you would have 768 MB of DDR in single channel mode

    actualy i have heard somewhere that you can take say a 512 stick put it in slot 1 and then take 2x 256 and put them in the other 2 slots. with this setup i have heard that it will be dual channel but i have not tried this nor can i confirm it

    wont work...you have to have 2 identical sticks to have dual channel

    Abit's original NF1 board could use all 3 DIMMs, but the last DIMM had to be single-sided. Other NF1 boards would cut some of the bandwith down. Not sure if this still applies to the NF2s, but I haven't been as up to date with them as I usually am.

    Why bother......dual channel is pointless on Athlon XPs, they can't utilize it to make it worth the trouble...if you run single channel you can usually get a higher overclock which more than makes up for it.

    Another pointless post from ya again I see which shows just how little ya know about AMD setups so keep ya comments to things ya may know about like Intel systems as that post just shows how well uninformed ya really are (not to mention how late ya are on this one).

    I'm with Wiggo on this one. The dual channel does make a drastic and noticeable difference with the Athlon XP processors. If you have doubts about it, then check out the difference in performance levels when comparing an nForce2 based motherboard with both the KT400 and KT600 models that are readily available to the public. Even the newer KT600 board doesn't get you to the same plateau in regards to either overall performance or memory bandwidth. If this isn't a significant benefit, then maybe I should change hobbies. :rolleyes2
