Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines (on page
28
).
•
DIMMs may be installed individually.
Single-processor Advanced ECC population order
For Advanced ECC mode configurations with a single processor, populate the DIMM slots in the following
order:
•
RDIMM: Sequentially in alphabetical order (A through F)
•
UDIMM: Sequentially in alphabetical order (A through F).
Multi-processor Advanced ECC population order
For Advanced ECC mode configurations with multiple processors, populate the DIMM slots for each
processor in the following order:
•
RDIMM: Sequentially in alphabetical order (A through F)
•
UDIMM: Sequentially in alphabetical order (A through F).
Mirrored Memory population guidelines
For Mirrored Memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines (on page
28
).
•
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.
Single-processor Mirrored Memory population order
For Mirrored Memory mode configurations with a single processor, populate the DIMM slots in the
following order:
•
RDIMM
o
First: A and B
o
Next: D and E
