Adding Video Memory
Your computer comes with 512KB or lMB of video memory.
You can increase your video memory up to 2MB by installing
additional 512KB, 40-pin, SOJ flat pack, video DRAM chips.
Additional video memory is useful for running
graphics-intensive applications or for supporting high
resolutions with many colors.

the ones in the illustration. If you’re not sure how to install
video memory chips, contact your Authorized EPSON Servicer
for assistance.
Follow these steps to install video memory:
1. Locate the video memory sockets, shown in “Locating the
Internal Components” on page 4-5.
2. If there is an option card in your way, remove it. See
“Removing an Option Card" on page 4-19 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.
