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.
Review "Electrostatic Discharge (on page 81 )" before installing hardware options into the server.
Memory options
The server memory can be expanded by installing PC5300 DDR2 unbuffered SDRAM DIMMs. The server
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 49 )" 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).
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.
