16GB DDR4 2666MHz SO-DIMM for laptop upgrades

This 16GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It uses a 260-pin SO-DIMM form factor with unbuffered, non-ECC architecture. The 2Rx8 organisation suits mainstream laptop memory controllers. Buyers seeking a direct replacement for Kingston ACR26D4S9D8MD-16 or KVR26S19D8/16 parts can use this module.

Verify DDR4 SO-DIMM slot

Confirm the laptop accepts DDR4 SO-DIMM memory and can run at 2666MHz or will down-clock automatically. Check the maximum capacity per slot and total system limit in the service manual. Ensure the platform does not require ECC or registered modules, as this stick is non-ECC and unbuffered. The 1.2V voltage is standard for DDR4.

Major-brand chips tested for reliability

Modules are built with major-brand DRAM components and undergo quality-assurance testing for dependable operation. The standard 260-pin edge connector fits any DDR4 SO-DIMM socket without adapters. Low-profile height clears most laptop chassis lids. Complimentary US-based technical support is available before and after purchase.

Questions about this item

Does the 16GB DDR4 2666MHz CL19 module come as a single stick or a kit, and is anything else needed to install it?

The package contains one 16GB 260-pin SO-DIMM. No additional parts are required; the module plugs directly into a compatible laptop memory slot.

Should I choose the 16GB 2666MHz CL19 version or look for a different speed or latency for my laptop?

Select this 2666MHz CL19 module when your system specifies DDR4 2666 (PC4-21300) SO-DIMM memory; matching the rated speed and latency avoids downclocking.

What does the 2666MHz rating mean once the 16GB stick is installed in my laptop?

The memory runs at 2666MHz with CL19 timing at 1.20V, delivering the standard PC4-21300 bandwidth for DDR4 SO-DIMM platforms.
