HP ProLiant BL465c Gen8 Server Blade - Manual (Page 39)

Hardware options installation 39
• 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 alphabetic order balanced between
the two processors: P1-A, P2-A, P1-B, P2-B, P1-C, P2-C, and so forth.
• For DIMM spare replacement, install the DIMMs per slot number as instructed by the system software.
For detailed memory configuration rules and guidelines, use the Online DDR3 Memory Configuration Tool
on the HP website ( http://www.hp.com/go/ddr3memory-configurator ).
DIMM speeds are supported as indicated in the following table.
Populated slots
(per channel) Rank Speeds supported
(MT/s)
1, 2 Single or dual 1600, 1333, 1066
1, 2
Quad* 1333
*LRDIMMs are the only supported quad-rank DIMMs for this server blade.
Advanced ECC population guidelines
For Advanced ECC mode configurations, observe the following guidelines:
• Observe the general DIMM slot population guidelines (on page 38 ).
• DIMMs may be installed individually.
Online spare population
For Online Spare memory mode configurations, observe the following guidelines:
• Observe the general DIMM slot population guidelines (on page 38 ).
• 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:
o A single dual-rank DIMM is not a valid configuration.
o LRDIMMs are treated as dual-rank DIMMs.
Population order
For memory configurations with a single processor or multiple processors, populate the DIMM slots in the
following order:
• LRDIMM: Sequentially in alphabetical order (A through H)
• RDIMM: Sequentially in alphabetical order (A through H)
After installing the DIMMs, use RBSU to configure Advanced ECC or online spare memory support.
Installing DIMMs
To install the component:
1. Power down the server blade (on page 12 ).
2. Remove the server blade (on page 13 ).
