Chapter 9 Motherboard and Component Replacement 9-9
9.3 Memory Modules
This section describes how to remove and fit the dual inline memory modules
(DIMMs).
The DIMMs are located in two banks, to the right of the CPU modules (see
FIGURE 9-4
). The banks comprise alternate slots, designated 0 (even slots) and 1 (odd
slots), and all four slots in either or both of the banks must be filled.
Caution –
Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an ESD-protected mat. Store ESD-sensitive
components in antistatic bags before placing them on any surface.
Caution – When you remove and replace a single DIMM, an identical replacement
is required. The replacement DIMM must be inserted into the same socket as the
removed DIMM.
Caution –
Each DIMM bank must contain at least four DIMMs of equal density (for
example, four 256 Mbyte DIMMs) to function properly. Do not mix DIMM densities
within any bank.
Caution –
Handle DIMMs only by the edges. Do not touch the DIMM components
or metal parts. Always wear a grounding strap when handling a DIMM.
