Chapter 4 Hardware Configuration 53
For maximum performance, install identical capacity DIMMs in all four memory
banks. The following table shows how to best populate the memory banks when
configuring your system for 512 Mbytes of memory.
Memory modules are delicate. Be sure to take appropriate precautions to avoid
damaging them through electrostatic discharge. For more information, see “How to
Avoid Electrostatic Discharge” on page 40.
Caution – Dual Inline Memory Modules (DIMMs) are made of electronic
components that are extremely sensitive to static electricity. Static from your clothes
or work environment can destroy the modules.
Do not remove any DIMM from its antistatic packaging until you are ready to install
it on the system board. Handle the modules only by their edges. Do not touch the
components or any metal parts. Always wear a grounding strap when you handle
the modules.
