5 Installing Additional Memory
Introduction
This chapter provides the procedures for opening the Processor/Memory Complex, installing a
memory board, installing DIMMs, and installing memory board DC-to-DC converters.
Tools Required
Use an anti-static service kit (3M 8501/8502/8503 or equivalent). This kit includes a static-dissipating
work surface, a chassis clip lead, and a wrist strap.
Memory Installation Guidelines
Each Memory Board can support from 1 GB to 32 GB. The server supports up to 64 GB of system
memory.
• Use only HP DIMMs, which are 3.3V, 168-pin, PC100, buffered SDRAM DIMMs in 256 MB,
512 MB, or 1 GB modules.
• DIMMs must be installed in the order indicated by the numbered slots on the memory board in
groups of four. Verify that the same size DIMM is used in any given group of four by using
the same HP part number.
• To ensure optimum performance when two memory boards are installed, the memory on each
board should be equal.
• Ensure both latches close on the DIMM when completely installed.
• When handling DIMMs, observe anti-static precautions to avoid damage.
