Use these guidelines when installing, upgrading, or replacing DIMMs:
Use only supported industry-standard DDR-3 DIMMs of these capacities:
16 GBytes (quad rank)
16 GBytes (dual rank) – requires system firmware 8.2.1.b or later.
32 GBytes – requires system firmware 8.2.1.b or later
Refer to the SPARC T4-1B Server Module Product Notes for possible updates to supported capacities.
Install quantities of 4, 8, or 16 DIMMs, in the correct slots:
4 DIMMs: CH1/D0 slots (white sockets)
8 DIMMs: CH1/D0 and CH0/D0 slots
16 DIMMs: All slots
All installed DIMMs must be the same type of DIMM architecture (same capacity and same rank classification).
Note - DIMMs of the same capacity are available with different rank classifications and cannot be mixed in the server module. For example, you cannot install a combination of quad-rank and dual-rank 16-GByte DIMMs. Refer to the label on the DIMM for capacity and rank information.
