Supported Dimm Configuration - Dell PowerEdge C8000 Hardware Owner's Manual

• Memory sparing and memory mirroring are supported on the sled system
board. Memory sparing requires that all the DIMMs are identically
populated in all 4 channels. One channel will be the spare and not
accessible as system memory until brought online to replace a failing
channel. For memory mirroring, two channels operate as mirrors for each
other, identical DIMMs must be installed in the same slots across both
channels.

Supported DIMM Configuration

For the sequence of the 16 DIMM sockets, see Figure 3-13. When you insert
the DIMM(s), always start with DIMM_A1. For single processor
configurations, the optimized memory module installation sequence is
A1/A2/A3/A4/A5/A6/A7/A8. See Table 3-2 for dual processor configurations.
