System-Specific DDR2 SO-DIMM

This 2 GB module uses 200-pin DDR2 technology rated at 667 MHz with CL5 timing. It operates at 1.8 V and is built as an unbuffered, non-ECC stick using major-brand chips. The part is validated for HP/Compaq Business Notebook nc6320 and nc6400 series laptops.

For DDR2 notebook upgrades only

It suits owners of the listed HP/Compaq models who need a single 2 GB SO-DIMM to reach the platform's 4 GB two-socket maximum. It is not for systems that require registered or ECC memory, nor for machines that take a different pin count or voltage. Buyers with other notebook families should verify their exact model before ordering.

200-pin DDR2 667 MHz form factor

The 200-pin SO-DIMM interface and DDR2 667 speed are the decisive specifications; the module will only fit and run in slots designed for that exact generation and pin layout. Confirm the target notebook uses PC2-5300 SO-DIMM sockets before purchase.

商品問答

Will the 667 MHz DDR2 speed limit performance under sustained heavy workloads?

The module runs at 667 MHz with CL5 timing, so bandwidth is capped at the DDR2 5300 specification during continuous use.

Does the unbuffered 1.8 V design run hot or loud in a notebook chassis all day?

No heat spreader is fitted, but standard DDR2 SO-DIMM power draw at 1.8 V is low and produces no audible noise.

Must my HP nc6320 or nc6400 already have a free 200-pin SODIMM slot for this stick to work?

Yes, the upgrade requires an available 200-pin DDR2 SO-DIMM socket in the compatible notebook.
