Single 4GB DDR2 800 SODIMM

This OWC module delivers 4 GB of DDR2 800 (PC2-6400) memory in a 200-pin SO-DIMM form factor. It runs at CL6 latency and 1.8 V without ECC or buffering, and carries JEDEC and RoHS compliance. The stick is designed for laptops, all-in-one systems and compatible NAS devices.

Buyers who need DDR2 800 CL6 at 1.8 V in a 200-pin

Systems requiring ECC, registered modules, a different voltage, a different pin count or any later DDR generation cannot use this stick. Builders wanting more than 4 GB per slot or a heat spreader should also look elsewhere.

DDR2 800 PC2-6400 CL6 200-pin 1.8 V specification

The speed, latency, voltage and pin count together determine whether the module fits the memory controller and slot. Match these four values exactly to the system requirements before ordering.

Questions about this item

Will this 200-pin DDR2 SODIMM fit in the memory slot of my laptop or all-in-one system?

The module uses the standard 200-pin DDR2 SO-DIMM form factor and runs at 1.8V, matching the physical and electrical requirements of compatible laptop and all-in-one memory slots.

Can I mix this CL6 PC2-6400 module with slower DDR2 memory already installed?

The system will run all installed DDR2 modules at the speed and timings of the slowest stick, so this CL6 800 MHz module will downclock to match any slower memory present.

How do I verify the module is recognised at its rated PC2-6400 speed after installation?

Check the memory speed reported in your system BIOS or a hardware information utility; it should show the module running at DDR2 800 (PC2-6400) with CL6 latency when operating as intended.
