Table: UDIMM Memory Configurations (Each Processor)

aRequires x4- or x8-based memory modules

E. Slots / Risers

PowerEdge R610 has 12 DIMM slots for memory. It does not have any riser cards for DIMM population.

F. Mirroring

PowerEdge R610 supports memory sparing in certain configurations, refer to embedded memory matrix spreadsheet in section 10-H for supported configurations.

The system supports memory mirroring if identical memory modules are installed in the two channels closest to the processor (memory is not installed in the farthest channel [channel 2]. Mirroring must be enabled in the System Setup program. In a mirrored configuration, the total available system memory is one-half of the total installed physical memory.

G. Advanced ECC (Lockstep) Mode

In this configuration, the two channels closest to the processor are combined to form one 128-bit channel. This mode supports Single Device Data Correction (SDDC) for both x4- and x8-based memory modules. Memory modules must be identical in size, speed, and technology in corresponding slots.
