DELL DDR2 400Mhz 1GB PC2-3200R ECC laptop RAM M393T2953CZ3-CCC

Dell DDR2 ECC module for legacy servers

This 1 GB DDR2 ECC module runs at 400 MHz and carries the PC2-3200R rating. It is built for Dell PowerEdge servers and Precision workstations that require registered error-correcting memory. The part number M393T2953CZ3-CCC identifies a Samsung-manufactured stick with gold contacts.

Registered DDR2 layout

The registered design adds a buffer that reduces electrical load on the memory controller in multi-module configurations. Gold-plated edge connectors resist oxidation and ensure consistent contact over repeated insertions. This single 1 GB stick fits the DDR2 slots found in the listed PowerEdge and Precision models.

Low-power DDR2 operation keeps thermals modest

DDR2 memory at 400 MHz draws less power than later generations, helping airflow in packed server enclosures such as the PowerEdge 1950 or 2950. The ECC function corrects single-bit errors without adding audible noise. Power draw remains within the limits of the original system power budgets.
