Identifying Dimms - Oracle SPARC T8-4 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
16 Gbyte 4 Gbit
32 Gbyte 4 Gbit
32 Gbyte 8 Gbit
64 Gbyte 8 Gbit
