• Never hold two or more memory modules together so that they touch. Do not stack memory modules
directly on top of each other during storage.
• Never touch the gold memory module connector contacts or allow these contacts to touch the outside of
the memory-module connector housing.
• Handle memory modules with care: never bend, twist, or drop a memory module.
• Do not use any metal tools (such as jigs or clamps) to handle the memory modules, because the rigid
metals may damage the modules.
• Do not insert memory modules while holding packages or passive components, which can cause package
cracks or detachment of passive components by the high insertion force.
• Make sure to adopt one of the supported configurations that is listed in “Memory module installation rules
and order” on page 151.
• In the case of installing PMEMs for the first time, read the rules and instructions in “PMEM and DRAM
DIMM installation order” on page 159 carefully, and make sure to adopt a supported configuration.

Procedure
Important:
• If you are installing memory modules on the processor and memory expansion tray, do not remove the
expansion tray. Install the modules while the expansion tray is installed in the chassis to avoid accidental
damages to components.
• Ensure that you have observed the installation rules and sequence in “Memory module installation rules
and order” on page 151.
• Before installing 3DS RDIMMs or PMEMs, make sure dual-rotor fan modules are installed in the system. If
not, follow the instructions in “Install the dual-rotor fan module upgrade kit” on page 178 to install the
dual-rotor fan upgrade kit.
Step 1. If any of the modules to be installed is PMEM, make sure to complete the following procedure
before physically installing the module:
1. Back up stored data in PMEM namespaces.
2. Disable PMEM security with one of the following options:
• LXPM
Go to UEFI Setup ➙ System Settings ➙ Intel Optane PMEMs ➙ Security ➙ Press to
Disable Security, and input passphrase to disable security.
• Setup Utility
Go to System Configuration and Boot Management ➙ System Settings ➙ Intel Optane
PMEMs ➙ Security ➙ Press to Disable Security, and input passphrase to disable
security.
3. Delete namespaces with command corresponding to the operating system that is installed:
• Linux command:
ndctl destroy-namespace all -f
• Windows Powershell command
Get-PmemDisk | Remove-PmemDisk
4. Clear Platform Configuration Data (PCD) and Namespace Label Storage Area (LSA) with the
following ipmctl command (for both Linux and Windows).
