[j-nsp] System board memory expansion on M7i

[Hyunseog Ryu]

I belive Juniper M20/M40 uses following memory for SSB.



Smart Modular Technology 
Part Number : SM572088094D6G6 
Desc : 64MB 168pin ECC memory 

You can check with your memory vendor. 

MemoryTen has a couple of them in stock.

2 slots is correct but without ECC. You can upgrade a SSB-E to 128mb by 
installing 2 64mb modules from 2 SSB-E in just one SSB-E.
However, I did not manage to find a 3rd party module working in the 
SSB-E yet.
The original one is a 64MB single-sided SDRAM, no ECC, PC66 with Samsung 
chips.

Only in M20 and M40.
