Built with ECC and Registered design, it prioritizes data integrity and stability for environments where uptime and accuracy matter. The 288-pin DIMM form factor is widely compatible with supported motherboards, making it a versatile upgrade option for boosting memory capacity without overhauling your entire system. Whether you’re a content creator, data analyst, developer, or gamer, this Crucial memory module helps you accelerate applications, reduce bottlenecks, and enjoy smoother performance across your digital workspace.

• Performance-driven capacity for multitasking — With 16GB of high-speed DDR4 memory in a single DIMM, you gain ample headroom for running multiple apps, browser tabs, and memory-intensive software simultaneously. The 2666 MHz speed and PC4-21300 bandwidth deliver improved data throughput, enabling quicker application launches, faster file operations, and overall snappier system feel. This is ideal for power users who juggle photo and video editing, virtual machines, large spreadsheets, development environments, and modern games that benefit from extra RAM. Pairing this module with your existing memory can unlock impressive multitasking efficiency and a more responsive desktop experience even under heavy load.
• Reliability you can trust with ECC and Registered design — This Crucial module features Error-Correcting Code (ECC) and Registered buffering, providing enhanced data integrity and stability for data-heavy workloads. ECC can detect and correct common memory errors on the fly, reducing the risk of system crashes and corrupted data during long-running tasks, scientific computations, database operations, and professional design work. Registered memory helps improve signal integrity and is favored in servers and workstation configurations where consistent performance is critical. While ECC and Registered features boost reliability, always verify your motherboard support to ensure full compatibility with ECC/Registered DIMMs in your PC setup.
• Broad compatibility with a future-proof upgrade path — This 288-pin DIMM follows the standard for DDR4 desktop memory, designed to slot into compatible motherboards that support ECC-registered modules. It complements a variety of CPUs and platforms, expanding your memory capacity without requiring a motherboard or CPU upgrade. Whether you’re replacing a smaller DIMM, expanding a dual-channel setup, or building a high-performance workstation, this module is a flexible choice that helps you maximize system performance and responsiveness across a wide range of use cases. As with all memory upgrades, confirm motherboard specifications and BIOS compatibility before installation to ensure optimal operation.
• Efficient power and thermal characteristics — DDR4 memory delivers improved power efficiency compared with older standards, helping reduce overall system power consumption and heat generation during heavy workloads. The module is designed to operate within standard voltage ranges for DDR4 platforms while maintaining stable performance under load. This efficiency contributes to cooler system temperatures, quieter operation, and better thermal headroom for sustained tasks such as video rendering, large-scale simulations, and running memory-intensive software overnight or during long sessions.
• Simple installation and immediate benefits — Upgrading with a single 16GB DIMM is straightforward on systems that support DDR4 ECC Registered memory. Power down the computer, discharge static, open the case, insert the module into an available 288-pin DDR4 slot, ensure it seating firmly with a click, close the case, and boot. In most cases, the system will recognize the new memory automatically, enabling you to begin enjoying faster multitasking and improved data handling right away. This upgrade path is ideal for extending the life of an aging workstation or breathing new life into a modern desktop used for demanding creative, development, or analytical tasks.

How to install Crucial 16GB DDR4 SDRAM Memory Module

• Power off your computer and unplug all cables. Ground yourself to prevent static discharge before handling the memory.
• Open the case to access the motherboard and locate the memory slots. Consult your motherboard manual if you’re unsure which slots to use for a single DIMM installation.
• Remove any existing DIMMs if you’re upgrading by carefully pressing the retaining clips outward to release the modules.
• Align the 288-pin DDR4 DIMM with the memory slot notch. The notch ensures correct orientation, so the module only fits one way. Insert firmly until the clips click into place on both ends.
• Reconnect power, boot the system, and enter the BIOS/UEFI if needed to confirm that the memory is detected at the correct speed. Save any changes and exit to start using your upgraded memory.

Frequently asked questions

• Q: Is this memory compatible with my motherboard? A: This module is a DDR4 ECC Registered 16GB DIMM designed for systems that support ECC and registered memory. Check your motherboard’s memory compatibility list or manual to confirm support for ECC/Registered DDR4 DIMMs and 288-pin DIMMs before purchasing.
• Q: What workloads benefit most from 16GB of DDR4 ECC Registered memory? A: Multitasking with many open applications, content creation (photo/video editing), virtualization, databases, scientific computing, software development environments, and heavy spreadsheet workloads all benefit from additional memory and improved stability provided by ECC and registered designs.
• Q: What is the speed and timing of this module? A: The module runs at DDR4-2666 MHz with CL19 latency, offering solid bandwidth for a wide range of tasks while balancing power efficiency.
• Q: Do ECC and Registered memory work in all desktops? A: ECC and Registered memory is typically intended for servers and workstations. Some high-end consumer boards may support ECC, but many standard consumer desktops do not. Always verify motherboard support for ECC and Registered DIMMs before upgrading.
• Q: How many modules should I install for optimal performance? A: For best performance, install memory in matched configurations and, if possible, pair modules in dual-channel or multi-channel kits per your motherboard’s guidelines. With a single 16GB DIMM, you’ll gain capacity and improved responsiveness, but dual-channel configurations with matched sticks often yield the greatest bandwidth gains.
