Reliable 16GB ECC SODIMM for our professional workstations. The error correction provides essential data integrity for complex tasks.
Consistent performance and perfect compatibility. This module ensures stable operation for our high-demand office computing and servers.
Excellent build quality and dependable throughput. The 2666MHz speed effectively boosts our system responsiveness and multitasking capabilities.
Professional grade RAM with robust ECC support. A trustworthy investment for maintaining peak performance in our compact systems.
Superior reliability and easy installation. It provides consistent stability for our mission-critical applications and high-traffic workflows.
The module is a 16GB DDR4-2666 ECC unbuffered SODIMM (260-pin) operating at 1.2V, offering error-correcting code for data integrity in laptops and compact systems.
This RAM module supports ECC (Error-Correcting Code) to detect and correct single-bit memory errors, improving system stability and data reliability.
It is unbuffered (UDIMM), providing direct communication between the memory controller and DRAM chips for low-latency operation in laptops and small form-factor devices.
This 260-pin SODIMM fits most DDR4-2666-capable laptops, mini-PCs, and compact workstations that support ECC unbuffered memory modules.
Each module delivers 16 GB of DDR4 memory, enabling smoother multitasking and larger in-memory data handling.
The module runs at a standard DDR4 voltage of 1.2 V, optimizing power efficiency and thermal performance.
Power down and unplug your laptop, open the memory compartment, align the notch, insert the module at a 30° angle, then press down until it clicks into place.
Mixing ECC and non-ECC modules is not recommended; for full ECC functionality and system stability, install identical ECC modules in all memory slots.
ECC memory detects and corrects single-bit errors in real time, reducing crashes, data corruption, and improving reliability in mission-critical applications.
It may fit in small-form-factor desktop SODIMM slots, but most standard desktops use 288-pin DIMMs; verify your motherboard supports 260-pin SODIMM form factors.
Install two 16 GB modules for a total of 32 GB, ensuring both slots support DDR4-2666 ECC unbuffered SODIMM.
The standard CAS latency is CL19 at DDR4-2666, balancing performance and stability for professional workloads.
Yes, it includes a limited lifetime warranty covering manufacturing defects and ensuring long-term reliability.
Run a memory diagnostic tool, such as MemTest86 or the built-in system memory test, to confirm stable operation without errors.
The module is rated for 0 °C to 85 °C operational temperature, ensuring reliable performance in typical laptop and mini-PC environments.
