Make sure all DRAM DIMMs installed on the server have the same product code. For
information about DIMM produce codes, visit the query tool at
http://www.h3c.com/cn/Service/Document_Software/Document_Center/Server/
•
For the configured memory mode to take effect, make sure the following installation
requirements are met:
Memory mode
DIMM requirements
Independent
•
If two processors are present, see
•
If four processors are present, see
Mirror
•
A minimum of two DIMMs for a processor.
•
This mode does not support DIMM population schemes that are not
recommended in
•
DIMM installation schemes:
If two processors are present, see
If four processors are present, see
Memory Rank
Sparing
•
A minimum of 2 ranks per channel.
•
DIMM installation schemes:
If two processors are present, see
If four processors are present, see
NOTE:
If the DIMM configuration does not meet the requirements for the configured memory mode, the
system uses the default memory mode (Independent mode).
