Is dual channel mode for RAM only good for Dual Core or Dual Processor based systems?

[xMax]

I have a P4 3.73 EE single core processor, a P5wd2 Asus board, and 2 x 512mb Corsair 5400UL RAM modules. The guy who setup my computer had the RAM in single channel mode, since thats what it said at bootup. I dont know why he did that. Im assuming he did it on purpose or he made a mistake. I cant reach him right now since he is off for christmass.

Anyways, so i removed one of the modules and placed it into a different slot, so that i went from 1 and 2 to 1 and 3, and now my computer boots up and says dual channel interleaved.

Should i keep it in dual channel or revert back to single channel mode?

Dual channel produces the most bandwidth, there is no point nor any gain what so ever running in single channel mode, and that is a given! No offence to your friend but he probably did not know what he was doing. (If running the standard DDR400) Single channel = 3200MB's, Dual channel = 6,400MB's, Simple no.

Especially on a P4 platform, it is much more beneficial due to their old model of CPU communication, aka the FSB, the one and only communication path to and from the processor. Where as we all know AMD has moved memory communication away from the FSB or HTT model, and has given it its own communication channel directly with the on die mem controllers, hence why AMD is not bandwidth starved.


Anyways Dual Channel "YAY" .. Single Channel "NAY"

yes. leave it as dual channel.

Excellent. Dual channel it is!
