DDR2 SODIMM upgrade for legacy laptops

This 4 GB module uses the DDR2 667 standard and a 200-pin SODIMM form factor. It targets owners of older notebooks or small-form-factor systems that require PC2 5300 memory. The stick is unbuffered, non-ECC and rated at 1.8 V with CL5 5-5-5 timings.

Fits 200-pin DDR2 slots without adapters

Installation simply requires an available SODIMM socket that accepts DDR2 667 modules. The single-rank 2Rx8 organisation leaves any second slot free for a matching stick. All installed memory will operate at the speed of the slowest module or the processor limit.

Steady operation at rated voltage and latency

Under continuous load the module maintains its specified 1.8 V and CL5 timings without throttling. The major-brand chipset and unbuffered design provide consistent throughput for everyday multitasking in compatible legacy platforms.

Questions about this item

Does the 2Rx8 organisation limit capacity on a single 200-pin slot?

Each module is a single 4 GB stick; the 2Rx8 rank layout is handled internally and does not restrict slot capacity.

How much heat does the 1.8 V unbuffered DDR2 SODIMM produce during continuous operation?

Standard 1.8 V DDR2 SODIMMs run cool enough for passive laptop cooling; no active airflow is required.

What must the notebook already provide to accept this CM512645300SO module?

A DDR2 SODIMM slot, 200-pin keying, and a BIOS that supports 667 MHz PC2-5300 memory.
