16GB DDR4 2133MHz ECC SODIMM for Microservers

This 16GB DDR4 2133MHz ECC SODIMM is built for microserver, server and workstation systems that require error-correcting memory. It runs at PC4-17000 speed with CL15 latency and operates at the standard 1.2V DDR4 voltage. The unbuffered 260-pin module installs directly into compatible SO-DIMM slots.

Capacity and headroom for ECC workloads

A single 16GB module provides substantial capacity for virtualization, file serving and database tasks that benefit from ECC protection. The 2133MHz speed handles typical microserver workloads smoothly, while the ECC function guards against data corruption. Systems needing more than 16GB total will require additional modules to expand further.

Kingston KTH-PN421E/16G compatible replacement

This module is a compatible equivalent for the Kingston KTH-PN421E/16G part number, simplifying sourcing for existing deployments. No heat spreader is included, keeping the profile low for dense chassis. Every unit undergoes quality assurance testing before shipment and is backed by a lifetime warranty with US-based technical support.

Questions about this item

Will this ECC SODIMM run in my older DDR4 laptop that only supports non-ECC memory?

This module is ECC unbuffered; it will only work in systems that explicitly support ECC SO-DIMMs, so check your laptop or microserver manual before installing.

How can I confirm the stick is running at DDR4 2133 CL15 after I install it?

Open the BIOS or a tool such as CPU-Z and verify the reported speed shows 2133 MT/s with CAS latency 15 at 1.2 V.

Does the 16 GB module come alone or with any extra parts I need to buy?

The package contains the single 260-pin DDR4 ECC SODIMM; no heat spreader, cables or additional hardware are included.
