  • Non-ECC CL13 timing provides stable operation without error-correction overhead

Dual-channel DDR3 kit for laptop upgrades

This OWC kit provides 8 GB of DDR3 memory in a matched pair of 4 GB SO-DIMMs. It targets owners of compatible laptops, mini PCs or NAS units that require 204-pin modules running at 1.35 V. The non-ECC design suits standard consumer platforms without error-correction overhead.

Steady throughput at CL13 1866 MHz

Rated at PC3L-14900 with a CAS latency of 13, the modules maintain their specified frequency during extended workloads rather than throttling after a brief burst. The low-voltage operation helps sustain performance within the thermal envelope of compact chassis where airflow is limited.

Low-profile SO-DIMM build for tight slots

Each stick uses a standard 204-pin edge connector and a slim profile that fits the narrow DIMM sockets found in ultrabooks and small-form-factor systems. The 1.35 V signalling reduces power draw compared with 1.5 V alternatives, easing strain on the memory controller during daily use.

Questions about this item

Does the 1.35V DDR3 kit run cooler than standard 1.5V modules during long sessions?

The 1.35V PC3L-14900 modules draw less power than standard 1.5V DDR3, so they generate less heat during all-day use.

What slot type must my laptop or mini PC provide for these 204-pin SO-DIMMs?

The kit uses the 204-pin SO-DIMM form factor and requires a DDR3-compatible slot.

Will the CL13 1866MHz sticks down-clock automatically in an older CL11 system?

Yes, the non-ECC modules will negotiate the highest common speed and latency supported by the platform.
