dual channel setup

[Alpha_One]

what i was talkin about was pure dual channel setup that will provide you the maximum speed... sure you can have single channel memory in dual channel boards paired in twos and as you said hindi mo maximize ang theoretical maximum bandwidth speed...

to minimize confusion buy memory that has two sides filled with chips if you want to maximize bandwidth and of course a board that supports dual channel set-ups...

Anyway gamers lang naman ang interesado sa ganito... or just buy higher frequency DDRs... DDR3-1066 at 1333 are on the way to simplify setup...

You're confusing your terms. Double-sided and single-sided refer to memory DENSITIES, not bandwidth. And I think you mean DDR2-1333, which is very rare and expensive (at the moment).

Double sided memory is NOT dual channel memory.

The difference between single sided and double sided RAM (ceteris paribus) is that the former has HIGHER DENSITY CHIPS than the other. They both run at the same speed!

Two single sided modules running dual-channel will run at the same speed as two double-sided modules running dual-channel.

There's no need to look for double-sided chips or whatnot to run full-speed dual-channel. Just pair two IDENTICAL sticks of RAM.

"Dual-channel memory" is nothing but a marketing term used to sell a pair of sticks that are guaranteed to run in dual-channel (usually with a corresponding "dual-channel friendly" warranty). If you bought a dual-channel kit and the modules were double-sided, that has nothing to do with "bandwidth" and "full speed" and is purely coincidental. Note that most high-capacity modules tend to be double-sided anyway (due to manufacturing/technological considerations).
