The 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. Unganging means that the two controllers work independently. This allows them to work asynchronously with reference to individual clocks with their one or two Dimms. I would set your Quad Core to unganged.

I would set the DRAM to 800Mhz with 4-4-4-12 as you are populating all four DRAM slots with 1066Mhz DRAM. This will bring you a better stability with that system.

It all looks correct to me so i would say that the system is setting correctly.

Sorry to bring this up again as i know it was a little while ago now, but i have just one question about ganged vs unganged!

- Just wondering is it better to have them ganged so that they are working together or is it more efficient to ahve them working on their own??

I'm assuming that ganged is better as 2 working together should be better than 2 working apart but i was just looking for clarification :)

Many Thanks

Ganged vs Unganged is not something that we have tested. These settings have to do with the memory controllers on the CPU, you may want to contact AMD for their recommendation.
