Help with memory setup

[Greenhoe]

I'm looking to purchase 12 GB of Ram for my 2009 Octo Mac Pro. I've heard it is always better to go with 3 sticks of Ram rather than 4 with the 2009 Mac Pro, but is it better to go with 6 sticks rather than 3?

What I'm looking to do is at 12 GB with either 4GB x 3 all on one side, or 2GB x 6 with 3 sticks on each side. I would prefer the 4GB sticks so I can upgrade later if needed to 24 GB.

What I wanted to know is will I lose performance by only have 3 sticks of memory rather than 6 or does it not matter?

I'm pretty sure 6 will still keep the triple channel...it's just two triple channels.

in any case, the performance benefit of triple channel is something like 2%, and hence not worth concerning yourself over. just buy whatever fits your needs and budget.
