Product Identity

This OWC kit supplies 16 GB of DDR3 laptop memory in a matched pair of 8 GB modules. It runs at 1333 MHz with CL9 latency and a standard 1.5 V operating voltage. The 204-pin SO-DIMM form factor targets laptops, all-in-one PCs and compatible NAS units.

Who It Suits

Owners of DDR3-based laptops, mini PCs or NAS appliances that accept 204-pin SO-DIMMs and support PC3-10600 speeds will gain a straightforward capacity boost. Systems limited to lower DDR3 speeds, proprietary module layouts or soldered memory cannot use this kit.

Deciding Specification

The memory operates at DDR3 1333 (PC3-10600) with CL9 timing; the host platform must support this exact speed grade for the modules to function at their rated performance.

Questions about this item

Will the 204-pin DDR3 SODIMM modules need replacement after a certain period?

The modules are built to JEDEC standards and carry a limited lifetime warranty, so no scheduled replacement is required under normal use.

What limit appears first when the 16 GB kit runs at 1333 MHz continuously?

The CL9 latency at 1.5 V is the primary timing constraint during sustained workloads.

How much heat and power do the two 8 GB sticks produce in all-day operation?

At 1.5 V the kit draws standard DDR3 power and runs without a heat spreader, so temperatures stay within normal laptop thermal limits.
