Kit purpose and fit

This OWC dual-channel kit supplies two 200-pin DDR2 SO-DIMM modules totalling 4GB for laptops, all-in-one desktops or NAS units that accept PC2-5300 memory. It is intended for owners of compatible legacy systems who want a straightforward capacity increase.

Capacity and headroom

Each module is a 2GB, 2Rx8 unbuffered DIMM rated at 667 MT/s with CL5 latency at 1.8V. The pair adds 4GB of addressable memory; systems limited to lower maximums or different DDR generations will not benefit.

Compliance and support

The modules are JEDEC-standard and RoHS compliant, tested to meet OEM specifications for a warranty-safe upgrade. OWC includes a limited lifetime warranty with free technical support and an advanced replacement programme.

Questions about this item

Will these two 2 GB DDR2 667 CL5 SODIMMs run in dual-channel with the single 1 GB stick already in my laptop?

The kit is a matched dual-channel pair of 2 GB modules at 667 MHz CL5; adding a third stick of different capacity or timing will force the controller to run all modules in single-channel mode.

How can I verify the 667 MHz CL5 speed is active after I install both modules?

Open the BIOS or a system-information tool such as CPU-Z and confirm the memory tab shows 667 MHz (PC2-5300) with CAS latency 5 for both slots.

Does the package include anything besides the two 200-pin SODIMMs, and do I need a screwdriver?

Only the two 2 GB DDR2 SODIMMs are in the box; a small Phillips screwdriver is required to open the memory compartment on most laptops.
