Adding Video Memory (OptiPlex GX1 Only)
You can upgrade video memory on an OptiPlex GX1 from 4 to 8 MB by installing a video-memory upgrade
module (OptiPlex GX1p systems come with 8 MB of video memory). Upgrading the video memory increases
video performance and allows you to use video modes for application programs that require high resolutions
and many colors.
CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals,
disconnect them from their electrical outlets, and then wait at least 5 seconds before you
remove the computer cover. Also, before you install an expansion card, see "
Safety First —
For You and Your Computer ."
To upgrade the video memory, perform the following steps:
1. Remove the computer cover according to the instructions in " Removing the Computer Cover ."
2. Remove the expansion-card cage as described in " Removing the Expansion-Card Cage ."
3. Locate the video-memory upgrade socket (labeled "VIDEO_UPGRADE") on the system board.
See Figure 1 .
4. Orient the module as shown in Figure 9 . Then install it in the socket.
Video memory modules are keyed, or designed to fit in the socket in only one direction.
The socket on the system board is notched so that the video memory module can be firmly seated only
one way.
a. Align the video memory module's edge connector with the slot in the center of the socket.
b. Press the video memory module's edge connector firmly into the socket.
c. Pivot the module down until it clicks into place.
d. If you do not hear a sharp click, remove the module and reinstall it.
