1GB DDR2 667 SO-DIMM for legacy laptops

This Kingston KVR667D2SO/1GR module adds 1GB of DDR2 memory to compatible notebooks. It uses a 200-pin SO-DIMM form factor and runs at 667MHz with a PC2 5300 rating. The unbuffered design operates at 1.80V with CL5 latency. It is intended for older systems that accept DDR2 SO-DIMM modules.

Suits owners of older DDR2 notebooks

Buyers repairing or upgrading a laptop that specifically requires 200-pin DDR2 667 memory will find this module fits the slot and voltage requirement. Systems that require a different pin count, a higher DDR generation, or ECC registered memory cannot use this part. It is not suitable for desktops or modern laptops.

200-pin DDR2 SO-DIMM interface decides fit

The 200-pin SO-DIMM edge connector and DDR2 signalling are the single specification that determines compatibility. If the service manual or motherboard specification calls for 200-pin DDR2 SO-DIMM at 1.80V, this module matches that requirement. A different pin layout or memory generation will prevent installation.

Questions about this item

Does the unbuffered DDR2 SO-DIMM need any periodic maintenance or replacement?

No — the module has no moving parts, no heat spreader and no firmware, so it runs until a cell fails without any scheduled upkeep.

What limits continuous throughput on this 667 MHz CL5 stick?

The 5.3 GB/s peak bandwidth of the PC2-5300 interface is the hard ceiling; sustained reads and writes cannot exceed that rate.

How much heat and power does a 1.80 V DDR2 module add during all-day use?

At 1.80 V the stick draws only a few watts and stays cool enough to operate without a spreader or active airflow.
