Dell OptiPlex GX620 compatible DDR2 module

This 1GB DDR2 667 (PC2-5300) DIMM is built specifically for Dell OptiPlex GX620 DT, MT and SFF desktops. It uses a 240-pin unbuffered non-ECC design with CL5 5-5-5 timing at 1.8V. The module carries a major brand chipset and is sold as a single stick for straightforward upgrades.

Capacity and headroom for legacy systems

The stick adds 1GB of DDR2 memory to systems that support up to 8GB across four sockets. It handles everyday office applications and older operating systems comfortably. Headroom disappears with modern multitasking or memory-intensive workloads that exceed the platform's maximum addressable space.

Thermals noise and power draw

Operating at the standard 1.8V DDR2 voltage, the module runs without a heat spreader and draws minimal power. Passive cooling from normal case airflow is sufficient. The component adds no audible noise and places negligible additional load on the system's power supply.

Domande su questo articolo

Will this 1 GB DDR2-667 DIMM work alongside the original memory already installed in my OptiPlex GX620?

This module is specified as compatible with the Dell OptiPlex GX620 DT, MT and SFF systems, which use DDR2-667 unbuffered non-ECC DIMMs.

How can I confirm the new stick is running at the correct 667 MHz speed and CL5 timing after installation?

Enter the system BIOS or use a tool such as CPU-Z; the memory tab should show DDR2-667 (PC2-5300) with 5-5-5 timings at 1.8 V.

Does the package include only the memory stick or are extra items such as a heat spreader or installation tool supplied?

The box contains one 240-pin DDR2 SDRAM DIMM; no heat spreader, tools or additional accessories are included.
