For the memory to work properly, you must install chips in the
following configuration (each bank contains two video memory
sockets).
Video memory chip configuration
1. Locate the memory chip sockets on the main system board,
shown on page 3-5.
Bank 0 contains two chips soldered to the system board, so
you cannot add video memory in this bank. Bank 1 contains
the two filled sockets closest to the soldered chips. Bank 2 is
the two middle sockets in each set of three and Bank 3
contains the remaining two sockets.
2. If there is an option card in your way, remove it. See
page 3-17 for instructions.
Caution
To avoid generating static electricity and damaging the
memory chips, ground yourself by touching the metal
surface on the inside of the computer’s back panel. Then
remain as stationary as possible while you install them.
3. Remove the memory chips from their package and inspect
each one. The pins should point inward at slightly less than
a 90° angle.
