Yet another single vs dual channel question

[PetarMI]

Hello. I have been reading around the subject of single and dual channel memory and there is an issue I cannot understand.
If a single 4GB memory module is capable of running only in single channel (unless it possible for one module to run in dual channel in which case I am seriously confused) isn't it better to have two 2GB modules running in dual channel and therefore having 128-bit bandwidth? After all data that can be sent per cycle is doubled so I guess this should improve performance.
I will be very thankful if someone could provide some information on that issue.

Yes, when dealing with dual channel memory, you will always get the best memory usage performance by using your sticks/modules in pairs. Also, it is advisable to always buy your dual channel RAM in kits of two or four sticks/modules (since these kits have sticks/modules that were matched at the factory) rather than buying individual sticks/modules one at a time.

Thank you for the quick answer. That cleared things up.
