• The system does not support combination of single-channel with
dual-channel memory.
• Use only DDR2 DIMMs. Other DIMMs will not fit into the socket.
Attempts to force a non-DDR2 DIMM into a socket will damage
and/or the socket or the DIMM.
• Hold DIMMs only by the edges. Do not touch the components or
gold edge connectors.
• Install DIMMs with gold-plated edge connectors only.
Important: Follow the DIMM module “Installation and
population order” on page 158 when installing and removing
DIMMs.
Installing DIMMs
Caution! Use extreme care when installing a DIMM. Applying too
much pressure can damage the connector. DIMMs are keyed and
can be inserted in only one way.
Note: DIMM slots on the memory module must be installed only
in certain configurations. Numbers next to DIMM slots correspond
to installation sequence. DIMMs must be installed in pairs.
1 Observe the ESD precautions and pre-installation instructions
described on page 33.
2 Remove the memory board. For instructions, see “Hot-removal of a
memory board” on page 53 or “Cold-removal of a memory board”
on page 70, depending on your server configuration.
