yes 2 sticks can provide dual advantage when they are of same feature(frequency etc.)
Can't say about using 4 sticks but make sure if you use 4 X 256, then you won't be left for any future upgradation.
Choose wisely.
Wait till other members reply.
Two similar Ram sticks will give the advantage of "dual channel" but only in case of motherbords supporting dual channel memory, that also if inserted in the proper slots.
In case of 4 sticks instead of 2 in Mobos like Nforce4, and Nforce4 Ultra, even if all the modules are similar and of 400 MHz, it will operate at 333 MHz, thus resulting in reduction of perfrmance, as far as I know.
Pl correct if I am wrong.
