2-power 2P-KF426S15IB1/16 - 16 GB - 1 x 16 GB - DDR4 - 2666 MHz - 260-pin SO-DIMM

When a laptop or compact system runs out of headroom, the usual fix is a memory upgrade—but not all SODIMMs are created equal. This 2-POWER 16GB DDR4-2666 module stands out by combining a true 1.2V low-voltage design with JEDEC-standard PC4-21300 compliance, so it delivers reliable performance without the heat or power draw of older DDR3L parts. Built on a 260-pin SO-DIMM form factor, it fits a broad range of notebooks, mini PCs, and all-in-one systems that demand a single high-capacity stick.

Highlights

• 16GB capacity in a single module—ideal for upgrading from 4GB or 8GB configurations
• DDR4-2666 (PC4-21300) speed with CL19 latency for balanced responsiveness
• Unbuffered, non-ECC design for standard consumer and business laptops
• 1.2V operating voltage reduces power consumption and thermal output
• 260-pin SO-DIMM form factor with no heat spreader for guaranteed fit in slim chassis

In daily use

Installing this module means fewer slowdowns when juggling browser tabs, office suites, and video calls. The 2666MHz data rate keeps the memory bus fed, while the 16GB capacity allows Windows or Linux to cache more data in RAM instead of swapping to a slower SSD. Because it runs at 1.2V, the module contributes less heat inside a cramped laptop shell, which can help sustain turbo boost clocks during longer workloads. The CL19 latency is typical for this speed class and provides a good balance between bandwidth and response time.
