16GB Dual-Channel DDR4 ECC Kit

This 16GB kit contains two 8GB DDR4 2666MHz SO-DIMM modules built for laptops, all-in-one PCs and compatible NAS devices. The ECC design detects and corrects single-bit errors, making it suitable for workloads that demand data integrity. Unbuffered operation keeps latency low for everyday multitasking.

JEDEC-Compliant 260-Pin SO-DIMM

Modules follow the JEDEC PC4-21300 standard at 1.2V and carry no heat spreader, so they fit tight SODIMM slots in thin chassis without clearance issues. The 260-pin edge connector matches the DDR4 laptop form factor, and the kit is backward compatible with 2400MHz and 2133MHz systems.

ECC Unbuffered CL19 at 2666MHz

The CL19 CAS latency at 2666MHz is the key figure that determines whether this kit matches your platform's supported speed and timing table; systems requiring registered or non-ECC memory cannot use these modules.

Questions about this item

Does the DDR4 2666MHz PC4-21300 interface cap speed at 2666MHz in a system that only supports 2400MHz?

The modules run at the highest speed the platform allows. In a 2400MHz system they operate at 2400MHz with matching timings.

What physical slot and pin count does this 260-pin SO-DIMM kit require for installation?

Each 8GB module uses the standard 260-pin DDR4 SO-DIMM form factor. Two adjacent SO-DIMM slots are needed for dual-channel operation.

How is the ECC SO-DIMM kit installed, and which step is most often missed?

Power off, open the access panel, align the notch with the slot key, press firmly until the side clips click. The step most often missed is fully seating both modules so both clips engage.
