49       3             1         1GB             0

looking at below value in particular:

Code:

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

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

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

I don't know what the performance impact of mixing memory boards will be. But you should provide your model number at least.
