Hardware options installation
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
You can expand server memory by installing PC2-6400 DDR2 SDRAM DIMMs. The system supports up to
four DIMMs for a maximum of 8 GB.
For DIMM slot locations and bank assignments, see "System board components (on page
11 )."
DIMM installation guidelines
Observe the following guidelines when installing additional memory:
• DIMMs installed in the server must be unbuffered DDR2 SDRAM with ECC.
• If only a single DIMM is installed, it must be installed in slot 1A.
• All DIMMs installed must be the same speed.
BIOS detects the DIMM population and sets the system as follows:
• Single-bank mode: Single DIMM installed in one bank only
• Single-bank interleaved mode: DIMMs installed in one bank with equal capacities per slot
• Dual-bank asymmetric mode: DIMMs installed in both banks, but of unequal capacities per bank
• Dual-bank interleaved mode: DIMMs installed in both banks with equal capacities per bank
The following table lists some, but not all, possible configurations. For best performance, HP recommends
dual-bank interleaved mode configurations.
