Dual channel memory: ganged or unganged?

[Brice3010]

My manual says bios need to be set in ganged for single dual channel. I did set it in unganged though, and cpuz shows "channels # : Dual".
I remember from a MSI mobo that unganged was needed for dual channel. But I am afraid I mix things up. Any suggestions please?

Ganged = dual channel mode for ram

Phenom has two memory controllers on the CPU.

Ganged is setting both memory controllers to work together which allows data (that is being used by all cores) to await on the queue until they are accessed.

Unganged means that the two controllers work independently. This allows them to work asynchronously with reference to individual clocks with their one or two Dimms.

Thanks for the very clear explanation.
What do you recommend as setting? Ganged or unganged? I have two identical dimms of 1Gb.

Put your sticks in Dual channel and run Ganged

Ganged results in higher bandwidth - there are 1x128 bit moved in 1T while unganged gives 2x64 bit.
