Computer Memory Solutions 4GB DDR2 667MHz SODIMM 200-pin memory upgrade

SKU CH-0BRZ-WQHZC

4GB DDR2 667MHz SODIMM module with 200 pins, CL5 latency and 1.8V operation for laptop memory upgrades

  • Capacity4GB
  • SpeedDDR2 667 (PC2 5300)
  • CAS Latency5
  • Timing5-5-5
  • Voltage1.8V
  • ECCNo
  • 4GB capacity extends system memory for DDR2 notebooks
  • 667 MHz DDR2-5300 speed matches legacy laptop specs
  • CL5 5-5-5 timings deliver stable data access
  • 8 V unbuffered SODIMM fits 200-pin slots
  • Major-brand chipset ensures reliable compatibility

Product Identity

This is a 4GB DDR2 SODIMM module rated at 667MHz with CL5 timing. It uses a 200-pin unbuffered design and runs at 1.8V. The part is built by Computer Memory Solutions and carries a limited lifetime warranty against manufacturing defects.

Suitability

It suits laptops or small-form-factor systems that accept DDR2 SODIMM memory at this speed and voltage. Buyers whose platforms require registered or ECC modules should look elsewhere, as should anyone needing a matched pair or a higher total capacity than a single 4GB stick provides.

Deciding Specification

The module operates at DDR2 667 (PC2 5300) with 5-5-5 timing. A system that only supports slower DDR2 speeds or a different pin count will not be compatible with this part.

商品問答

Does my laptop need a 200-pin SODIMM slot to use this module?

Yes, this is a 200-pin SODIMM designed for DDR2 667 (PC2 5300) systems. Verify your device accepts unbuffered, non-ECC memory at 1.8V before purchasing.

If I keep an existing DDR2 stick, will both run at the same speed?

The supplier notes that all installed memory runs at the slowest module's speed or the CPU limit, so mixing speeds will downclock this 667 MHz stick to match the slower one.

How can I confirm the 4 GB capacity is recognised after installation?

Boot into the OS and check System Information or Task Manager; a 64-bit operating system is required to address the full 4 GB provided by this single module.
