Memory options
The memory subsystem in this server can support DIMM and UDIMM. Both types are referred to as DIMMs
when the information applies to both types. When specified as UDIMM, the information applies to that type
only. All memory installed in the server must be the same type.
The server supports single- and dual-rank DIMMs operating at 800 MHz, with a maximum memory capacity
of 8 GB.
Memory subsystem architecture
The memory subsystem in this server is divided into channels. Each processor supports two channels, and
each channel supports two DIMM slots, as shown in the following table.
Channel Slot Slot number
1 A 1
2 B 2
This multi-channel architecture provides enhanced performance in Advanced ECC mode. This architecture
also enables the Mirrored Memory and Lockstep memory modes. This server supports UDIMMs.
DIMM slots in this server are identified by number and by letter. Letters identify the slots to populate for
specific AMP modes. Slot numbers are reported by ROM messages during boot and are included in error
reporting.
