dual channel ram configuration for dual processors on Asus..

Im making a system using the K8N-DL and 2x Opteron 265s. I want to get
the full potential out of the board with bus speeds and utilizing dual
channel ram. The mobo manual states for dual cpu you need this ram bank
configuration: DIMM_A1+DIMM_A2=DIMM_B1+DIMM_B2=DIMM_A3+DIMM_B3. Does
this mean you need 6 sticks of ram? or 3 or what? I was planning on 6x
512 sticks but I read something that said using 6 sticks will degrade
ram performance. I just want to buy the right stuff. Can someone
advise me please? Thanks

I built one, the RAM instructions in manual are slightly incorrect. The
pairing is wrong. If u follow the pairing plan u end up with non-dual
channel. You need to match the colours for each 2 sticks of RAM.

The first 4 slots are for CPU 1. The last 2 slots are for the CPU 2.

Remember that there may be a limitation for the amount of RAM that the OS
can use. For example if its a server and you're using Windows Small
Business Server 2003 then its 4GB limitation.

The manual is probably the worst manual I've ever seen for a RAID enabled
motherboard. It doesn't even have a section about the RAID setup, not even
1 page or 1 paragraph.
