Four green DDR2 memory modules with black chips

SAMSUNG

SAMSUNG M378T5663QZ3-CF7 8GB 4x2GB DDR2 800 PC2-6400U memory upgrade

SKU CH-NNDM-A5ZZW

8GB DDR2-800 kit with four 2GB double-sided modules for PC2-6400U systems

  • 8 GB total capacity from four 2 GB modules
  • DDR2 800 MHz speed for responsive system performance
  • PC2-6400U specification ensures broad compatibility
  • Double-sided design maximises density per slot

8 GB DDR2 kit for legacy systems

This kit supplies eight gigabytes of DDR2 memory in four 2 GB modules rated at PC2-6400U DDR2 800. It is intended for older workstations or servers that still require double-sided DDR2 DIMMs to reach their maximum supported capacity.

Four-module layout fills available slots

Populating four DIMM slots with matched modules lets the platform run in its native multi-channel mode without mixing densities. Buyers who need more than 8 GB or a faster memory standard will have to choose a different platform, as this kit is limited to the DDR2 800 specification.

Questions about this item

Does the DDR2 800 rating sustain throughput when all four modules run continuously?

The PC2-6400U DDR2 800 specification defines the peak transfer rate; sustained throughput depends on the host chipset and memory controller.

How much heat do the double-sided modules generate during all-day operation?

Double-sided DDR2 modules draw standard DDR2 power; actual temperature rise varies with case airflow and ambient conditions.
