looking at below value in particular:

0x3200000000 1GB 1 BankIDs 48
0x3300000000 1GB 1 BankIDs 49

it has only one bank id's and interleave way?

 

[KenCunningham]

Presumably these are 1GB DIMMS? Others will know whether that's and acceptable config, but I don't see much wrong with it.

I want to be good, is that not enough?

 

[eb222]

but they have interleave factor of 1 each while others have 16 -would this cause a performance issue?

 

[KenCunningham]

Presumably the interleave factor depends somewhat on the number (16) of 256Mb units. I'm not really too clued up about interleaving - must do some more research, but perhaps a good starting point is this:
