3.1.3.4.1 
Mirrored Mode Memory Configuration 
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. 
3.1.3.4.2 
Sparing Mode Memory Configuration 
The 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.
