Upgrade Options The system board has various accommodations for system upgrades including: • Microprocessor upgrade • Main memory expansion • Video memory expansion These upgrades are summarized in the following subsections, and installation procedures are provided for the various chassis configurations in Chapters 4, 5, 6, and 7. Microprocessor/L2 Cache Upgrades On the OptiPlex GXa and OptiPlex NX systems, the microprocessor and secondary L2 cache memory are implemented in an SEC cartridge/heat sink assembly. Upgrade to a higher-performance microprocessor is accomplished by snapping out the old assembly and installing an upgrade assembly as higherperformance microprocessors become available. Main Memory Expansion The three DIMM sockets on the system board can accommodate combinations of 16-, 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. Video-Memory Upgrade Option You can upgrade video memory from 2 to 4 MB by installing an optional videomemory 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. Computer Service Information The following subsections provide service-related information about the computer. Unless otherwise specified, the information applies to all chassis configurations. Remote Management Support Features (Optional) For OptiPlex GXa and OptiPlex NX systems equipped with the enhanced manageability system board and power supply and an optional Wakeup On LAN-capable network card, the following tasks may be performed by a system administrator at a remote location. 1-16 Dell OptiPlex GXa and OptiPlex NX Systems Service Manual

pgrade Options
The system board has various accommodations for system upgrades including:
•
Microprocessor upgrade
•
Main memory expansion
•
Video memory expansion
These upgrades are summarized in the following subsections, and installation
procedures are provided for the various chassis configurations in Chapters 4, 5,
6, and 7.
Microprocessor/L2 Cache Upgrades
On the OptiPlex GXa and OptiPlex NX systems, the microprocessor and sec-
ondary L2 cache memory are implemented in an SEC cartridge/heat sink
assembly. Upgrade to a higher-performance microprocessor is accomplished by
snapping out the old assembly and installing an upgrade assembly as higher-
performance microprocessors become available.
Main Memory Expansion
The three DIMM sockets on the system board can accommodate combinations
of 16-, 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.
