NOTE:
•
If the DIMM configuration does not meet the requirements for the configured memory mode,
the system uses the default memory mode (Independent mode).

In
, the black DIMM slots (for example, the F1 slot) are grey colored,
and the white DIMM slots (for example, the F0 slot) are not colored.

Guidelines for installing a mixture of PMem 200 and DDR4 DIMMs
When you install PMem 200 and DDR4 DIMMs on the server, follow these restrictions and
guidelines:
•
Make sure their corresponding processors are present before powering on the server.
•
Make sure the PMem 200 DIMMs have never been used on any other products. If they have
been used on any other products, they might be unusable on the server.
•
Make sure all DDR4 DIMMs have the same product code and all PMem DIMMs have the same
product code. For information about DIMM product codes, use the query tool available from
http://www.h3c.com/cn/Service/Document_Software/Document_Center/Server/
•
Depending on the processor and DIMM configuration, use the schemes shown in
, and
NOTE:
In
and
, the black DIMM slots (for example, the F1 slot) are grey
colored, and the white DIMM slots (for example, the F0 slot) are not colored.
If one processor is present, populate DIMMs as shown in

When 12 DIMMs are installed:
1. Compared with the not recommended population scheme, the recommended scheme provides better bandwidth
performance.
2. SNC, Hemi, and SGX are not supported by the recommended scheme.
