General DIMM slot population guidelines Observe the following guidelines for all AMP modes: ● Install DIMMs only if the corresponding processor is installed. ● When two processors are installed, balance the DIMMs across the two processors. ● White DIMM slots denote the first slot of a channel (Ch 1-A, Ch 2-B, Ch 3-C, Ch 4-D). ● Do not mix RDIMMs and LRDIMMs. ● When one processor is installed, install DIMMs in sequential alphabetic order: A, B, C, D, E, F, and so forth. ● When two processors are installed, install the DIMMs in sequential alphabetical order balanced between the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C, and so forth. ● When single-rank, dual-rank, and quad-rank DIMMs are populated for two DIMMs per channel or three 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 DIMM spare replacement, install the DIMMs per slot number as instructed by the system software. For more information about server memory, go to the HP website http://www.hp.com/go/memory. DIMM speeds are supported as indicated in the following table. Populated slots (per channel) 1 2 2 3 Rank Single, dual-, or quad-rank Single- or dual-rank Quad-rank Single-, dual-, or quad-rank Speeds supported (MT/s) 2133 2133 2133 1600 Depending on the processor model, the number of DIMMs installed, and whether LRDIMMs or RDIMMs are installed, the memory clock speed can be reduced to 1600 MT/s. Advanced ECC population guidelines For Advanced ECC mode configurations, observe the following guidelines: ● Observe the general DIMM slot population guidelines (see General DIMM slot population guidelines on page 44). ● 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 (see General DIMM slot population guidelines on page 44). ● Each channel must have a valid online spare configuration. 44 Chapter 5 Hardware options installation

General DIMM slot population guidelines
Observe the following guidelines for all AMP modes:
●
Install DIMMs only if the corresponding processor is installed.
●
When two processors are installed, balance the DIMMs across the two processors.
●
White DIMM slots denote the first slot of a channel (Ch 1-A, Ch 2-B, Ch 3-C, Ch 4-D).
●
Do not mix RDIMMs and LRDIMMs.
●
When one processor is installed, install DIMMs in sequential alphabetic order: A, B, C, D, E, F, and so
forth.
●
When two processors are installed, install the DIMMs in sequential alphabetical order balanced between
the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C, and so forth.
●
When single-rank, dual-rank, and quad-rank DIMMs are populated for two DIMMs per channel or three
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 DIMM spare replacement, install the DIMMs per slot number as instructed by the system software.
For more information about server memory, go to the HP website
go/memory
.
DIMM speeds are supported as indicated in the following table.
Populated slots (per channel)
Rank
Speeds supported (MT/s)
1
Single, dual-, or quad-rank
2133
2
Single- or dual-rank
2133
2
Quad-rank
2133
3
Single-, dual-, or quad-rank
1600
Depending on the processor model, the number of DIMMs installed, and whether LRDIMMs or RDIMMs are
installed, the memory clock speed can be reduced to 1600 MT/s.
Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
●
Observe the general DIMM slot population guidelines (see
General DIMM slot population guidelines
on page
44
).
●
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 (see
General DIMM slot population guidelines
on page
44
).
●
Each channel must have a valid online spare configuration.
