DIMMs, therefore, must be added four at a time in the same bank. The following
figure shows the memory banks on the main logic board.

Configuration Rules
Memory DIMMs must be added four at a time within the same bank, and each bank
used must have four identical capacity DIMMs installed (for example, four 32-Mbyte
DIMMs, or four 64-Mbyte DIMMs).
Memory bank A must always be filled.
DIMM capacities can differ from one bank to the next—for example, four 32-Mbyte
DIMMs installed in bank A and four 64-Mbyte DIMMs installed in bank B.
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 64.
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.
