General DIMM slot population guidelines
Observe the following guidelines for all AMP modes:
•
Do not mix LRDIMMs and RDIMMs.
•
White DIMM slots denote the first slot of a channel (Ch 1-A, Ch 2-B, Ch 3-C, Ch 4-D).
•
Install DIMMs in sequential alphabetic order: A, B, C, D, E, and so forth.
•
When single-rank, dual-rank, and quad-rank DIMMs are populated for two DIMMs per channel, always
populate the higher number rank DIMM first (starting from the farthest slot). For example, first quad-rank
DIMM, then dual-rank DIMM, and then lastly single-rank DIMM.
•
DIMMs should be populated starting farthest from the processor on each channel.
For more information about server memory, see the HP website (

).
The DIMM speeds supported in this server are listed in the following table:
Populated slots
(per channel)
Rank
Speeds supported (MT/s)
1
Single, dual, or quad-rank 2133
2
Single, dual, or quad-rank 2133
Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines.
•
DIMMs may be installed individually.
Online spare population guidelines
For Online Spare memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines.
•
Each channel must have a valid online spare configuration.
•
Each channel can have a different valid online spare configuration.
•
Each populated channel must have a spare rank. A single dual-rank DIMM is not a valid configuration.
Mirrored Memory population guidelines
For Mirrored Memory mode configurations, observe the following guidelines:
•
Observe the general DIMM slot population guidelines.
•
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.
