What this is

This 16 GB DDR4 2666 ECC SODIMM module is built for laptops and compact workstations that require error-correcting memory. It runs at 1.20 V with a CL19 latency and uses a standard 260-pin SO-DIMM form factor. The unbuffered design suits systems that do not support registered modules.

Thermals noise and power

Operating at the standard 1.20 V DDR4 voltage keeps power draw low and heat output minimal inside a closed chassis. No active cooling is required and the module adds no audible noise. The low-voltage operation also helps preserve battery life in mobile platforms.

Upgrade path and fit

This module replaces Kingston KSM26SED8/16HD, KSM26SED8/16MR, KTD-PN426E/16G, KTH-PN426E/16G and KTL-TN426E/16G equivalents. It is suited for DDR4 2666 slots that accept ECC unbuffered SODIMMs. Buyers who need non-ECC memory or a different pin count should look elsewhere.

Въпроси за този артикул

How do I install this 260-Pin DDR4 SODIMM and what step do people often miss?

Power off the laptop, open the memory compartment, align the notch on the module with the slot key, insert at an angle, then press down until the retention clips click — the step often missed is fully seating both clips so the module sits flat.

What maintenance or replacement will this ECC unbuffered module need over time?

No scheduled maintenance is required; the module uses major-brand chips at 1.20 V and is tested for reliability. Replace only if memory errors appear or a larger capacity is needed.

What limit appears first when this CL19 2666 MHz module runs sustained workloads?

The CAS latency of 19 and 2666 MHz data rate set the throughput ceiling; under continuous load the memory controller will hit that bandwidth limit before thermal throttling occurs.
