Introduction
If more than one option is being installed, read the installation instructions for all the hardware options
and identify similar steps to streamline the installation process.

WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and
the internal system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the server before beginning any
installation procedure. Improper grounding can cause electrostatic discharge.
Memory options
You can expand server memory by installing PC4200 DDR2 unbuffered SDRAM DIMMs. The system
supports up to four ECC DDR2 SDRAM DIMMs.
supports up to four ECC DDR2 SDRAM DIMMs.
NOTE: By default, the server is set to Advanced ECC Support. Refer to "HP ROM-Based Setup Utility (on
page
)" for more information.
The server supports standard memory configuration for maximum performance with up to 8 GB of active
memory (four 2-GB memory modules).
memory (four 2-GB memory modules).
Interleaving and non-interleaving memory configuration
The server supports interleaving and non-interleaving memory configurations. Interleaving memory
increases bandwidth by enabling simultaneous access to multiple blocks of data. For example, to overlap
read-writes, the server divides the system memory between pairs of DIMMs, and then writes to and reads
from each DIMM concurrently. For an interleaving configuration, always install identical DIMMs in pairs.
For a non-interleaving configuration, install a single DIMM in slot 1 only.

DIMM installation guidelines
Observe the following guidelines when installing additional memory:
•
DIMMs installed in the server must be unbuffered DDR2 SDRAM, 2.5 V, 64 bits wide, and ECC.
