Note – For optimum memory performance, consider interleaving issues when
installing DIMMs. See Section C.1.3.5, "System Memory Interleaving" on page C-14.
Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an antistatic mat. Store ESD-sensitive components in
antistatic bags before placing them on any surface.
1. Before installing a DIMM, review the following guidelines:
DIMMs are arranged in two banks, 0 and 1. Each bank has four connectors
labeled "0" or "1".
The workstation must have four or eight DIMMs installed to operate.
Each DIMM bank must contain four DIMMs of equal size to function properly.
For example four 128-Mbyte DIMMs in bank 0, four 256-Mbyte DIMMs in bank 1.
The default location for DIMMs installed at the factory is the four connectors
labeled "0" (
