Installing a memory module

vThe maximum operating speed of the server is determined by the slowest DIMM in the server.

vIf you install a pair of DIMMs in DIMM connectors 2 and 5, the size and speed of the DIMMs that you install in DIMM connectors 2 and 5 must match each other. How ever, they do not have to be the same size and speed as the DIMMs that are installed in DIMM connectors 1 and 4.

vYou can use compatible DIMMs from various manufacturers in the same pair.

vWhen you install or remove DIMMs, the server configuration information changes. When you restart the server, the system displays a message that indicates that the memory configuration has changed.

See “System-board internal connectors” on page 107 for the location of the DIMM connectors on the system board.

To install a DIMM, complete the following steps:

1.Read the safety information in “Important Safety Information” on page 1 and “Guidelines for trained service technicians” on page 115.

2.Turn off the server and peripheral devices and disconnect the power cords and all external cables, if necessary.

3.Remove the cover (see “Removing and installing the cover” on page 119).

4.Remove the DIMM air baffle (see “Removing and installing the DIMM air baffle” on page 121).

5.Open the retaining clip 2 on each end of the DIMM connector.

Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, open and close the clips gently.
