Lenovo ThinkSystem SR950, Setup Manual, Page: 181 / 390

Example:
Intel Xeon 52 15L
and
Intel Xeon Platinum 82 80M
If the presently installed processors do not support DCPMMs, replace them with the processors that
support DCPMMs.
• Supported memory capacity range varies with the following types of processors.
–
Large memory tier (L):
The processors with
L
after the four digits (for example:
Intel Xeon 5215 L
)
–
Medium memory tier (M):
The processors with
M
after the four digits (for example:
Intel Xeon Platinum
8280 M
)
–
Other:
Other processors that support DCPMMs (for example:
Intel Xeon Gold 5222
)
In addition, you can take advantage of a memory configurator, which is available at the following site:

DC Persistent Memory Module (DCPMM) setup
Follow the instructions in this section to complete required setup before installing DCPMMs for the first time,
determine the most suitable configuration, and install memory modules accordingly.
Complete the following steps to finish system setup to support DCPMMs, and install the memory modules
according to the designated combination.
1. Update the system firmware to the latest version that supports DCPMMs (see “Update the firmware” on
page 256).
2. Make sure to meet all the following requirements before installing DCPMMs.
• All the DCPMMs that are installed must be of the same part number.
• All the DRAM DIMMs that are installed must be of the same type, rank, and capacity with minimum
capacity of 16 GB. It is recommended to use Lenovo DRAM DIMMs of the same part number.
3. Refer to “DCPMM installation order” on page 176 to determine the most suitable combination and the
following:
• Number and capacity of the DCPMMs and DRAM DIMMs to install.
• Check if the presently installed processors support the combination. If not, replace the processors
with ones that support the combination.
4. Based on the determined DCPMM combination, acquire the DCPMMs, DRAM DIMMs and processors if
necessary.
5. Replace the processors if necessary (see “Processor and heat sink replacement” in
Maintenance
Manual
).
6. Remove all the memory modules that are installed (see “Remove a memory module” in
Maintenance
Manual
).
7. Follow the slot combination in “DCPMM installation order” on page 176 to install all the DCPMMs and
DRAM DIMMs (see “Install a memory module” on page 355).
8. Disable security on all the installed DCPMMs (see “Configure DC Persistent Memory Module (DCPMM)”
on page 261).
9. Make sure the DCPMM firmware is the latest version. If not, update it to the latest version (see
https://
sysmgt.lenovofiles.com/help/topic/com.lenovo.lxca.doc/update_fw.html
).
10. Configure DCPMMs so that the capacity is available for use (see “Configure DC Persistent Memory
Module (DCPMM)” on page 261).
Adding memory modules with DCPMMs
Follow the instructions in this section to add memory modules to the existing configuration with DCPMMs.
