The board tht I am working on has 2 process. Each of them has 6 DIMM slots. If you
plug 1 dimm into each slot, the SPD address will be,
Channel PCB
----------------
P0:
DIMMA0 50h
DIMMA1 51h
DIMMA2 52h
DIMMB0 53h
DIMMB1 54h
DIMMB2 55h
P1:
DIMMA0 50h
DIMMA1 51h
DIMMA2 52h
DIMMB0 53h
DIMMB1 54h
DIMMB2 55h
If you plug 1 dimm in P0DIMMA0 and the other in P1DIMA0, the SPD address
will be 50h and 55h.
So I am confused. If we got an active spd 0x50 on the SMBUS, what will it be?
It seems that we can not plug more that 8 dimm even if we have 12 slots, correct?
