Simmtec, Inc 4GB DDR2 SODIMM 200 pin 667MHz PC2-5400/PC2-5300 CL5 1.8V Unbuffered NON-ECC desktop RAM

SKU CH-MRRJ-8Q6TK

A 4 GB DDR2 SODIMM module with 200 pins running at 667 MHz and CL5 latency for older laptop upgrades

  • Capacity4GB
  • CAS LatencyCL5
  • 4GB capacity lets you run more programs at once
  • 667MHz speed matches PC2-5300 and PC2-5400 system requirements
  • CL5 latency keeps data access responsive
  • 8V operation reduces power draw and heat
  • 200-pin SODIMM form factor fits compatible laptop slots

4 GB DDR2 SODIMM for legacy notebooks

This module delivers four gigabytes of DDR2 memory in a 200-pin SODIMM form factor. It targets owners of older laptops that require PC2-5300 or PC2-5400 speeds and cannot accept newer memory types.

Fits DDR2 SO-DIMM slots running at 1.8 V

The stick plugs directly into a standard 200-pin DDR2 SO-DIMM socket without adapters. Its unbuffered, non-ECC design keeps the electrical load light, leaving the memory controller free for other system tasks.

CL5 latency at 667 MHz under continuous use

Rated at CAS latency 5.0, the module maintains its specified timing during extended workloads rather than only in short bursts. The 1.8 volt operation helps sustain stability when the system runs warm for long periods.

Questions about this item

What is the first limit reached under sustained use?

The module runs at 1.8 V, so the voltage ceiling is the first hard limit during continuous operation.

What happens to noise, heat or power when the module runs all day?

There are no moving parts, so the module adds no audible noise; power draw stays at the 1.8 V specification and heat output remains low for a DDR2 SODIMM.

What must the buyer already own for this 200-pin DDR2 SODIMM to work?

A system with a 200-pin DDR2 SO-DIMM slot that accepts PC2-5300 or PC2-5400 modules at CL5 latency.
