Install a memory module

Use this information to install a memory module.

About this task

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

Attention

• Read the following sections to ensure that you work safely.

  • Installation Guidelines

  • Safety inspection checklist

• Memory modules are sensitive to static discharge and require special handling. In addition to the standard guidelines for 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 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 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.

  • DIMM fillers must be installed in unused slots for proper cooling.

The following illustration shows the location of the memory module connectors on the system board.

You can find the memory module tool attached to the DIMM comb.

Procedure

1. Carefully use the memory module tool to press down the retaining clips on each end of the memory module connector.
   Note

   Memory module tool is recommended due to space limitations caused by location of water loop tubes through the memory section.

   Attention

   • Memory modules are static-sensitive devices. The package must be grounded before it is opened.

   • To avoid breaking the retaining clips or damaging the memory module connectors, open and close the clips gently.

2. Touch the static-protective package that contains the memory module to any unpainted metal surface on the outside of the node. Then, remove the memory module from the package.
3. Align the memory module with the slot, and gently place the memory module on the slot with both hands.
4. Firmly press both ends of the memory module straight down into the slot until the retaining clips snap into the locked position.

   Note

   If there is a gap between the memory module and the retaining clips, the memory module has not been correctly inserted; open the retaining clips, remove the memory module, and then reinsert it.
