Installing A Memory Module - IBM 8836 - Eserver xSeries 306 Installation Manual

To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v Limit your movement. Movement can cause static electricity to build up around
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
v Remove the device from its package and install it directly into the server without
v Take additional care when handling devices during cold weather. Heating reduces

Installing a memory module

The following notes describe the types of dual inline memory modules (DIMMs) that
your server supports and other information that you must consider when installing
DIMMs:
v Your server supports 256 MB, 512 MB, and 1 GB DIMMs, for a maximum of 4
v The amount of usable memory will be reduced depending on the system
v Your server comes with one 512 MB DIMM installed in DIMM connector 1. If your
v If you install a second pair of DIMMs in DIMM connectors 2 and 4, they do not
v Install only 2.5 V, 184-pin, double-data-rate (DDR), PC2700 or PC3200,
v When you restart the server, the system displays a message indicating that the
