3.1.3.4.2 DIMM Sparing Mode Memory Configuration
The MCH provides DIMM 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.
