SPARC T8-4 Server Service Manual

Identifying DIMMs

Each DIMM is affixed with an identifying label. The first four characters on the label describe the DIMM memory capacity; the second four characters describe the rank classification. Use these labels to identify the DIMMs installed in the server, to verify that any replacement DIMMs are compatible, or to confirm that upgrade DIMMs may be installed in a supported configuration.

As of System Firmware version 9.10.3, the following DIMM configurations are supported.

DIMM Capacity DRAM Density Rank Classification Label 16 Gbyte 4 Gbit Dual-rank x4 2Rx4 32 Gbyte 4 Gbit Quad-rank x4 4Rx4 32 Gbyte 8 Gbit Dual-rank x4 2Rx4 64 Gbyte 8 Gbit Quad-rank x4 4Rx4 128 Gbyte 16 Gbit Quad-rank x4 2S2Rx4
