Service Manual

NOTE: The memory modules must be rated to run at 100 MHz or faster.
Memory Module Installation Guidelines
Starting with the socket nearest to the system board's center, the DIMM sockets are labeled "DIMM3"
through "DIMM0" (see Figure 15
). When you install memory modules, follow these guidelines:
Install a DIMM in socket DIMM3 (the socket toward the center of the board) before socket DIMM2,
socket DIMM2 before socket DIMM1, and so on.
The reason for installing memory in the back-most socket first is for ease of future installations.
If you install different sizes of memory modules, install them in order of descending capacity, beginning
with the highest-capacity DIMM in socket DIMM3.
You do not need to install memory modules in pairs.

Table 1 illustrates the valid memory configurations based on these guidelines.
