It does not have any riser cards for DIMM population.f. mirroringPowerEdge R610 supports memory sparing in certain configurations, refer to embedded memory matrixspreadsheet in section 10-H for supported configurations.The system supports memory mirroring if identical memory modules are installed in the two channelsclosest to the processor (memory is not installed in the farthest channel [channel 2]. Mirroring must beenabled in the System Setup program. In a mirrored configuration, the total available system memory isone-half of the total installed physical memory.G. advanced ecc (lockstep) modeIn this configuration, the two channels closest to the processor are combined to form one 128-bitchannel. This mode supports Single Device Data Correction (SDDC) for both x4- and x8-based memorymodules. Memory modules must be identical in size, speed, and technology in corresponding slots.Table: UDIMM Memory Configurations (Each Processor)
