The three DIMM sockets on the system board can accommodate combina-
tions of 32-, 64-, and 128-MB DIMMs up to a total memory capacity of
384 MB. Main memory can have either 72-bit parity (ECC) DIMMs or 64-bit
nonparity DIMMs.
You can upgrade video memory from 4 to 8 MB by installing an optional video-
memory upgrade module in the video-memory upgrade socket on the system
board. Adding video memory increases the system's video performance and
provides additional modes for high-resolution/expanded color applications.
NOTE: See the online System User's Guide or Chapter 6, "Installing System
Board Options," in the Reference and Installation Guide for additional upgrade
information.
The following subsections provide service-related information about the com-
puter. Unless otherwise specified, the information applies to all chassis
