System-Specific DDR2 Module

This 1 GB DDR2 PC2-6400 module is built for the Dell Optiplex 755. It plugs directly into compatible desktops to add memory capacity. The part is new and sourced from major manufacturers such as Samsung, Kingston, Hynix, Smart, Corsair, Elpida, Micron, or Nanya.

Single-Gigabyte Capacity Limits

One gigabyte suits light office tasks and legacy operating systems. Multitasking with several modern applications will exhaust the available space quickly. Systems needing more memory for current workloads will find this capacity insufficient.

Standard DDR2 Thermal Profile

DDR2 memory at this density runs at modest power levels inside the Optiplex 755 chassis. No extra cooling is required beyond the system's standard airflow. The module operates silently with no moving parts.
