Two green DDR2 SO-DIMM modules with gold contacts and black chips

A-Tech

A-Tech 4GB (2x2GB) DDR2 667MHz SODIMM PC2-5300 CL5 1.8V 200-Pin Laptop RAM

SKU CH-8M6H-P3AA6

A 4 GB dual-channel DDR2 kit running at 667 MHz with CL5 timing and standard 1.8 V for 200-pin laptop slots

  • Total capacity4 GB (2 × 2 GB)
  • Rated speedDDR2 667 (PC2 5300)
  • CAS latencyCL5
  • Rated voltage1.8 V
  • Buffer typeUnbuffered
  • Kit configurationDual Channel Kit

Capacity 4GB (2 x 2GB)

Speed DDR2 667 (PC2 5300)

CAS Latency CL5

  • Dual-channel kit doubles bandwidth with two matched 2GB modules
  • DDR2 667MHz speed rated at PC2-5300 for faster data transfer
  • Low 1.8V standard voltage reduces power draw and heat
  • CL5 latency timing improves memory response speed
  • 200-pin SO-DIMM form factor fits compatible laptop slots

DDR2 SO-DIMM Upgrade Kit

This A-Tech kit supplies 4 GB of DDR2 laptop memory as two matched 2 GB modules. The 200-pin SO-DIMMs run at 667 MHz (PC2-5300) with CL5 latency at the standard 1.8 V. They are non-ECC and unbuffered, built for dual-channel operation in compatible notebooks and all-in-one systems.

Suitable for older DDR2 laptops

Owners of laptops, notebooks or all-in-one PCs that accept DDR2 SO-DIMMs can use this kit to increase memory capacity and enable dual-channel bandwidth. Systems that require a different DDR generation, a different pin count, ECC functionality or registered modules cannot use these sticks.

200-pin DDR2 SO-DIMM form factor

The decisive specification is the 200-pin DDR2 SO-DIMM interface; only machines designed for this exact module type will accept the kit. Verify the supported memory specification of your system before purchase to ensure physical and electrical compatibility.

Questions about this item

Does my laptop need a 200-pin DDR2 SO-DIMM slot to use this kit?

Yes, these modules are 200-pin DDR2 SO-DIMMs and will only fit a socket built for that exact form factor.

Can I keep one existing 2 GB DDR2 module and add this 4 GB kit for 6 GB total?

The kit is a matched 2 x 2 GB pair designed for dual-channel operation; mixing it with a different module may prevent dual-channel mode or cause instability.

How do I confirm the memory is running at 667 MHz with CL5 timings after installation?

Check the memory tab in CPU-Z or the BIOS memory information screen; both will show the operating frequency and CAS latency values.
