The system has four DIMM slots that support up to 8 GB maximum system memory (2 GB in each of
the four DIMM slots). The DIMM slots are divided into two channels of two DIMM slots each.
Memory installation guidelines
Observe the following important guidelines when installing memory modules:
• Use only HP supported PC2-6400 DDR2-800 unbuffered ECC DIMM in 512 MB, 1 GB or 2 GB
capacities.
• Supported DIMM configurations include:
○ Single DIMM (non-interleaving) – It must be installed in the DIMM 1A slot.
○ Two DIMMs (interleaving) – For optimum memory performance, populate DIMM slots 1A and
3B.
○ Four DIMMs
CAUTION: DIMMs can be damaged by improper handling. Always use an anti-static wrist
strap and grounding mat, and discharge static electricity before touching DIMMs.
