Memory Riser Information Screens
The Memory Board Information screen allows you to view the status of each memory riser in the system.
When a DIMM fails during BIST (Early POST - MRC) all four DIMMs in the lock-step DDR3 Channel Pair will be
disabled. This is due to DDR3 Channel Failure & Lock-step.
