Dell OptiPlex GX320 replacement board

The DELL CU395 system board is a direct replacement for the OptiPlex GX320 desktop. It uses an LGA 775 socket supporting Pentium 4 and Celeron processors. Two memory slots accept DDR2-533 or DDR2-667 modules up to a total of 2GB. A single PCI Express x16 slot and dual ATI LAN chipsets are integrated.

Upgrading a failed or faulty GX320 motherboard

This board replaces a damaged original unit in an existing OptiPlex GX320 chassis. The jump is worth it when the current board has failed and the system must stay on the LGA 775 platform. It restores the original specification without requiring a move to a newer socket or memory standard. No CPU or RAM upgrade path beyond the listed limits exists on this board.

Installation fits the original GX320 chassis

The board mounts directly into the OptiPlex GX320 case using the stock standoffs and I/O shield. Front-panel headers, power connectors and the CPU cooler retention bracket align with the original layout. The most common issue is sourcing matching DDR2-533 or DDR2-667 memory, as newer DDR generations are physically incompatible and will not fit the slots.
