Memory Ganged vs Un-Ganged

If you have noticed your BIOS report “Un-ganged Memory” and are worried if something’s wrong; dont be :)
Nothing’s wrong.

Know few things before deciding to change it over to “Ganged mode”:

It is AMD’s technique similar Nvidia’s Locked vs unlocked architecture.
Basically, it allows you to use your RAM in dual channel vs single channel.
Ganged = Dual channel mode for ram. All cores get access to 100% of the ram.
Unganged = Single channel. Each core gets access to a stick of ram.

Ganged and Un-ganged are both dual channel memory modes, as long as you are using pairs of RAM.
Ganged means you will run one large 128bit dual channel bus, and unganged means you will use 2x64bit dual channel bus.

Which is better depends on what apps you use. Heavy multitasking will benefit from un-ganged mode.
Gaming applications benefit from ganged mode.

In theory, the unganged mode is better as each core will get access to data quicker.
Un-ganged mode also allows you to control memory clocks independently.
