Computer Memory Solutions 2x4GB DDR2 667 SODIMM 2Rx8 memory upgrade

Matched-pair DDR2 SODIMM kit

This kit supplies two 4 GB DDR2 SODIMM modules rated at 667 MHz with CL5 timings and 1.8 V operation. The unbuffered non-ECC design uses 2Rx8 organisation and fits standard 200-pin laptop slots. Modules are built by Computer Memory Solutions with major-brand chipsets to reduce compatibility risk.

Thermals and power in normal use

At the specified 1.8 V the modules draw modest power typical for DDR2 SODIMMs and run without active cooling in a notebook chassis. The CL5 5-5-5 timings keep latency low for the 667 MHz data rate, so the memory controller stays cool during everyday workloads. No fan or heatsink is required.

Upgrade scope and when it matters

The pair replaces a single module or mismatched sticks to enable dual-channel bandwidth on platforms that support it. The jump is worthwhile when the system currently runs below 4 GB total or uses slower DDR2 speeds, and a 64-bit operating system is present to address the full 8 GB capacity. Mixing with other DDR2 modules will force all memory to the slowest installed speed.
