When operating in mirrored mode, both branches operate in lock step. In mirrored mode, branch 1 contains a replicate copy of the data in branch 0. The minimum DIMM configuration to support memory mirroring is four DIMMs, populated as shown in Figure 14, above. All four DIMMs must be identical with respect to size, speed, and organization.
To upgrade a four DIMM mirrored memory configuration, four additional DIMMs must be added to the system. All four DIMMs in the second set must be identical to the first with the exception of speed. The MCH will adjust to the lowest speed DIMM.
3.1.3.4.2Sparing Mode Memory ConfigurationThe MCH provides memory sparing capabilities. Sparing is a RAS feature that involves configuring a DIMM to be placed in reserve so it can be use to replace a DIMM that fails. DIMM sparing occurs within a given bank of memory and is not supported across branches. There are two supported Memory Sparing configurations.
Single Branch Mode Sparing
Dual Branch Mode Sparing
