Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines (on page 25).
•
DIMMs may be installed individually.
Multi-processor Advanced ECC population order
For Advanced ECC mode configurations with multiple processors, populate the DIMM slots for each
processor sequentially in alphabetical order (A through C).
Mirrored Memory population guidelines
For Mirrored Memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines (on page 25).
•
Always install DIMMs in channels 1 and 2 for each installed processor.
•
Do not install DIMMs in channel 3 for any processor.
•
DIMMs installed on channel 1 and channel 2 of an installed processor must be identical.
•
In multi-processor configurations, each processor must have a valid Mirrored Memory configuration.
•
In multi-processor configurations, each processor may have a different valid Mirrored Memory
configuration.
Multi-processor Mirrored Memory population order
For Mirrored Memory mode configurations with multiple processors, populate DIMM slots A and B for
each processor. Do not populate slot C.
After installing the DIMMs, use RBSU to configure the system for mirrored memory support ("Configuring
Lockstep Memory population guidelines
For Lockstep memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines (on page 25).
•
Always install DIMMs in channels 1 and 2 for each installed processor.
•
Do not install DIMMs in channel 3 for any processor.
•
DIMM configuration on channel 1 and channel 2 of a processor must be identical.
•
In multi-processor configurations, each processor must have a valid Lockstep Memory configuration.
