Maximum memory operating speed is 1066 MHz. This also applies to supported DIMMs rated for higher speeds.
Supported DIMMs include single-, dual-, or quad-rank 4 GB, 8 GB, 16 GB and 32 GB JEDEC–standard, DDR3 low voltage ECC RDIMMs.
All DIMMs on a CMOD must be the same density and organization.
Do not mix dual-rank 16 GB DIMMs with quad-rank 16 GB DIMMs on a CMOD. Mixing DIMMs of different rank or density degrades performance.
Single-rank DIMMs (marked 1Rx8) and dual-rank DIMMs (marked 2Rx4) do not include heat spreaders.
Quad-rank DIMMs are marked 4Rx4 and include heat spreaders. DIMMs with heat spreaders have two U-shaped metal clips on the top of the DIMM.
The following figure shows a DIMM with heat spreaders.

Each CMOD supports up to 32 DIMMs in two possible configurations: 16 or 32 total DIMMs.
Maximum of 128 DIMMs for an 8-socket Sun Server X2-8
Maximum 64 DIMMs for a 4-socket Sun Server X2-8
Note that when using the 16 DIMM per CMOD configuration, only the blue and white sockets should be populated to maximize performance.
DIMM slots are colored coded with the following population order:
Blue
White
Black
Green
DIMM slots must be populated in matching pairs of identical DIMMs (from the same memory kit) within a processor:
D0/D4
D1/D5
D2/D6
D3/D7
D8/D12
D9/D13
D10/D14
D11/D15
