Using all 4 memory banks in dual channel systems

[Stoneburner]

If you use all 4, do they all have to be teh exact same type of memory, or do just the matching pairs have to be the same? I'm guessing the answer is all 4 have to be the same because the few people iv'e seen try this all use the same, but I've seen nothing that officially states this.

what mobo are you using? I've only seen dual channel setups with 3 mem banks.

Yes you can..

Most people use matched pairs just for optimal performance and better o/cability..

It's also harder to overclock with more sticks of RAM

Will it work in dual channel mode with a setup of 2 of one kind, and 2 of another?

The "Spec" supports two memory sticks of the same kind PER channel and will work in the example below in "DUAL Channel Mode", so for example:

Channel A :
256MB Brand X
256MB Brand X

Channel B:
512MB Brand X
512MB Brand X

But Marvie is right, more memory makes less likely to overclock higher. Of course the more memory is always helpfull. I would try not to use all 4 if I could. Remember as well that channels are alternated on motherboards. So in a row outwards from CPU you would most likely see 256-512-256-512 in the example above... Also, try to use same vendor in all cases or at least, in same channels - try to use memory manufactured in the same lot for optimum compatibility.
