Just some info for you guys.

ganged mode is 1x128bit dual channel

unganged is 2x64 bit dual channel

Some motherboards are reporting unganged as single channel at boot, this is not true, if you see anyone saying they have defective memory please point them to this post.

Ganged will give higher sandra bandwidth at this time than unganged, this is because sandra does not fully support phenom and is working in 1 thread mode. Once sandra supports Phenom unganged 2x64bit will take the lead

If you are running multi threaded benchmarks you need to be in unganged mode, this is the fastest way of running the system.

Can you freely change between unganged and ganged in the BIOS?
