Memory Interleaving question on E4500 server

2007-12-24 23:03:00

I have an E4500 with 3 CPU/Memory boards, each
populated with identical memory SIMMS and CPU modules
(each SIMM is 256 MB, each bank= 2GB) CPU are all
400Mhz with 8 MB cache.

Question:

Should I get 6-way interleave memory for this
configuration ( 6 memory banks)

Here is what I get when I run "prtdiag" command:
(I got a mixture of 4 way and 2 way interleave)

Please reply. I will summarize
