OWC 16GB DDR4 2666MHz for Lenovo Legion

This 288-pin DDR4 UDIMM adds 16GB of system memory to Lenovo Legion C530-19ICB and C730-19ICO desktops. It operates at 2666MHz with a CL19 latency and a standard 1.2V supply. The module is non-ECC, unbuffered and built to JEDEC specifications.

Suits owners of listed Legion towers.

The memory is validated only for the two Lenovo Legion models named in the specifications. Builders upgrading a different motherboard, a laptop, a workstation requiring ECC or a platform that needs registered DIMMs should look elsewhere.

16GB single-module capacity decides fit

A single 16GB stick fills one slot and raises total system memory by that amount. If the target machine already has a full complement of slots or the user needs a different total capacity, this module will not match the requirement.

Questions about this item

Does the 16GB DDR4 2666MHz CL19 UDIMM ship as a single stick, or do I need to buy a second module for dual-channel?

The module is sold individually as one 16GB stick; add a second identical module to run dual-channel on the Legion C530 or C730.

Should I choose the 2666MHz CL19 version or a faster kit for my Legion C530-19ICB?

The C530-19ICB and C730-19ICO both support 2666MHz natively; faster modules will simply down-clock, so this CL19 kit is the correct match.

Will the 2666MHz PC4-21300 rating actually run at that speed once installed in a Legion C730-19ICO?

Yes, the system's memory controller defaults to 2666MHz with this JEDEC-standard CL19 module — no BIOS tuning required.
