Bios message - DDR3 Unganged mode ??

Hi tall
I installed some new memory -- now single 4GB chips are cheap enough I upped the ram in my machine to 16 GB.

Works fine -- but on boot there is always a message DDR3 Unganged mode.
System boots OK though.

can I ignore it or do i have to swap the memory modules around -- i don't really want to get at the computer which i've stored out of the way (it's a SERVER) and open it all up again.

A quick google search does the trick

It is amd's version of Nvidia's Locked vs unlocked architecture.

basically allowing 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.

In theory, the unganged mode is better as each core will get access to data quicker. In theory.

Ganged vs. Unganged Mode - -
So to answer your question. No, you don't need to worry about that message. It is just letting you know that you're running in unganged mode.
