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.

Perguntas sobre este artigo

How do I install the 200-pin SODIMM modules and what step is often missed?

Align the notch on each 200-pin SODIMM with the slot key, insert at an angle, then press down firmly until both side clips click; the step often missed is not pressing hard enough to engage both clips fully.

What maintenance or replacement will the DDR2 667 memory need over time?

No routine maintenance is required; if a module fails, the limited lifetime warranty from Computer Memory Solutions covers exchange or repair for manufacturing defects.

What limit appears first when running the 1.8V 2Rx8 modules under sustained load?

The DDR2 667 speed and CAS 5 latency set the bandwidth ceiling, so sustained workloads will hit the memory controller throughput limit before thermal throttling occurs.
