Capacity 4GB (2 x 2GB)

  • Dual-channel kit doubles bandwidth with matched 2×2 GB modules
  • DDR2 800 speed rated at PC2-6400 for faster data throughput
  • Low 1.8 V operation reduces power draw and heat
  • CL6 latency tightens timing for snappier response
  • JEDEC and RoHS compliant for warranty-safe upgrades

DDR2 800 SO-DIMM kit

This kit supplies two 2 GB DDR2 800 modules in 200-pin SO-DIMM form, giving a total of 4 GB. It is intended for laptops, all-in-one PCs and compatible NAS units that accept PC2-6400 memory running at 1.8 V.

Dual-channel unbuffered upgrade

The two modules are matched for dual-channel operation in systems with two SO-DIMM slots. They are unbuffered, non-ECC and carry no heat spreader, so they fit standard slot spacing without extra clearance requirements.

JEDEC and ROHS compliant modules

Each module meets JEDEC specifications and ROHS requirements, making the upgrade warranty-safe for supported OEM platforms. The kit is tested for compatibility and includes access to OWC installation videos for DIY guidance.

Questions about this item

Will the CL6 latency hold up during long sessions?

The modules run at CL6 latency and DDR2 800 speed, so timing stays consistent under sustained load.

How much heat and power do two sticks draw all day?

Each stick operates at 1.8 V without a heat spreader; total draw is low and typical for DDR2 SODIMMs.

My laptop only has one SODIMM slot — can I use just one module?

The kit includes two 2 GB sticks; both must be installed together for the rated dual-channel 4 GB capacity.
