Whats needed for using dual channel memory?

Question

The ddr2 memory modules must have a "dual channel" feature or the only have to be identical?.

Answer 1

They only have to be identical, and the motherboard has to support it. They do not have to say"dual channel" as long as they are identical.

Answer 2

The dual channel is meant to double the data that the memory processes. "The dual channel configuration alleviates the problem by doubling the amount of available memory bandwidth. Instead of a single memory channel, a second parallel channel is added. With two channels working simultaneously, the bottleneck is reduced. Memory must be installed into matching memory slots, which are usually color coded on the motherboard. Each memory module in each slot should be identical to the one in its matching slot.

While it is best that the memory is the same, manufacturer, speed, CAS rating, it is not imperative. I would highly suggest it for system stability.
