    I just purchased a GA-7N400 PRO2 and 2 sticks of 512mb Kingston Hyper x
    PC2700. What slots should the memory sticks be in to get Dual Channel and
    what are the benefits of Dual Channel? Do I need to change a jumper or go
    into the bios to initiate Dual Channel or is it automatically detected based
    on what slots the chips are in?

    Put them in dimm1 & dimm3 or dimm 2 & dimm 3. I just put them in the orange
    slots 1&3. Will recognize at post. You should see a message 'dual channel

    Dual Channel supposedly increases the memory bandwidth - I haven't really
    noticed much difference.

    Use same coloured slots if you have 2 memory sticks - normally 1 & 3. If
    you want to use more than 2, read the manual - the config is different for
    single sided sticks vs dual sided ones.

    Because my memory is dual sided I can run sticks in slot 1,2 and and get
    dual channel, but if I add another stick to slot 4, it goes back to single

    good board otherwise

    Someone is reading the manual wrong. 2 sticks in 1 & 2 (A) will run as
    single channel. 2 sticks in 3 & 4 (B) will run as single channel.

    2 sticks must be run in 1&3 or 2&3 or 1&4 or 2&4 to enable the DC feature.

    You can use 1 & 2 only if you have a 3rd stick in slot 3 or 4 according to
    the manual.
    And as Peter said you have to watch your DS or SS ram.

  5. Rudy is correct, there was a typo in my note which meant to say "slots 1,2
    and 3"

    Just added another 512 module. Put it in slot 2. Now have 1, 2, &3 filled
    1.5 gig. Awesome. Autocad & Solidworks run like a dream come true.
