Computer Memory Solutions 2GB (2x1GB) DDR2 400MHz CL3 Non-ECC DIMM Dell Optiplex GX280

System-specific DDR2 kit for Dell Optiplex GX280

This 2 GB kit contains two 1 GB DDR2 SDRAM DIMMs rated at 400 MHz with CL3 timing. It is built for Dell Optiplex GX280 series desktops that require unbuffered non-ECC memory. Each module uses a 240-pin interface and operates at 1.8 V. Buyers upgrading a different platform or needing ECC registered modules cannot use this kit.

Matched pair eliminates single-channel bottleneck

The two modules are sold as a tested pair so the system can run in dual-channel mode when the board supports it. Using a matched set avoids timing mismatches that can cause instability or reduced throughput compared with mixing individual sticks. No heat spreaders are included and the chipset brand may vary between units.

Straightforward DIMM installation

Installation follows the standard 240-pin DIMM procedure: power off, open the chassis, align the notch and press until the latches click. Because the platform is older, the BIOS may not automatically detect the optimal 3-3-3 timings; manual adjustment in setup is sometimes required. Systems limited to a single DIMM slot or requiring registered memory will not accept this kit.
