Install a memory module

Follow instructions in this section to install a memory module.

About this task

See Memory module installation rules and order for detailed information about memory configuration and setup.

To avoid potential danger, make sure to read and follow the safety information.

  • S002
    disconnect all power
    The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
  • Make sure to adopt one of the supported configurations listed in Memory module installation rules and order.
  • Memory modules are sensitive to static discharge and require special handling. Refer to the standard guidelines at Handling static-sensitive devices:
    • Always wear an electrostatic-discharge strap when removing or installing memory modules. Electrostatic-discharge gloves can also be used.
    • Never hold two or more memory modules together so that they do not touch each other. 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 memory 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.
  • Read Installation Guidelines and Safety inspection checklist to make sure that you work safely.

  • Touch the static-protective package that contains the component to any unpainted metal surface on the node; then, remove it from the package and place it on a static-protective surface.

Firmware and driver download: You might need to update the firmware or driver after replacing a component.


  1. Make preparations for this task.
    1. In the case of altering memory configuration, refer to Memory module installation rules and order to ensure a valid configuration is planned.
    2. Locate the slot to install the memory module.
      Figure 1. Location of the memory module slots on the system board
      Location of the dimm slots
  2. Install a memory module into the slot.
    • To avoid breaking the retaining clips or damaging the memory module slots, open and close the clips gently.
    • If there is a gap between the memory module and the retaining clips, the memory module has not been correctly inserted. In this case, open the retaining clips, remove the memory module, and then reinsert it.

    1. Carefully press to open the retaining clip.
    2. Align the memory module with the slot.
    3. Firmly press both ends of the memory module straight down into the slot until the retaining clip snaps into the locked position.
  3. If there are plans of installing additional memory modules, proceed to install all of them.
