With support for both Intel XMP 3.0 and AMD EXPO profiles, this kit is made to fit smoothly into a wide range of platforms.
This particular kit comes in a 32GB configuration, split across two 16GB modules, which makes it well suited to gaming rigs, creative workstations, and productivity machines alike. By reaching speeds of 6400MT/s, it pushes performance well beyond the DDR4 era, while maintaining compatibility with the latest AMD and Intel chipsets. The low-profile design also makes it a versatile choice for builds where space and cooling considerations matter.
Crucial’s Pro Series DDR5-6400 is aimed at users who prefer performance without unnecessary extras such as RGB lighting. Its understated styling hides impressive bandwidth and fast timings, providing users with a straightforward option that still delivers a noticeable impact in demanding applications. This makes it a strong candidate for those who value efficiency and speed without added distractions.
Design and Functionality
The Crucial Pro Series DDR5-6400 memory kit is built with simplicity in mind, offering a clean and professional look that avoids unnecessary embellishments. Its low-profile heat spreaders are designed to fit easily into a wide range of builds without obstructing larger CPU coolers or compact cases.
The heat spreaders are made from aluminium, which provides adequate thermal management while keeping the overall height to just 31mm. This design choice ensures compatibility with small-form-factor systems where clearance is often limited.
Crucial has opted for a matte black finish on the modules, complemented by subtle geometric accents that add a modern touch. For users building white-themed systems, the kit is also available in an all-white variant that blends seamlessly with lighter colour schemes.
By excluding RGB lighting, Crucial targets users who prefer a minimalist build aesthetic. This choice not only maintains a sleek appearance but also reduces potential compatibility issues with software-driven lighting ecosystems.
Each module is clearly labelled with its speed, timings, and capacity, making it easy for builders to identify and configure them during installation. This practical detail helps avoid confusion when working with multiple memory kits or upgrading existing systems.
The modules are housed in straightforward plastic packaging, which protects them during transit without overcomplicating the unboxing process. All the essential information is printed on the packaging, so users can confirm specifications at a glance.
Functionality extends to performance flexibility, with both Intel XMP 3.0 and AMD EXPO profiles included. This dual support allows the kit to be installed in either Intel or AMD systems, making it a versatile option for a wide audience.
In terms of stability, the memory is engineered to handle high-speed operation without compromising reliability. The default JEDEC profile provides a safe fallback option if the overclocked profiles are not supported by a particular motherboard.
The modules are optimised for next-generation multicore CPUs, ensuring that bandwidth and latency align with the demands of modern gaming and productivity workloads. This optimisation helps reduce bottlenecks and maintain consistent performance across applications.
The Crucial Pro Series DDR5-6400 strikes a balance between practicality and performance. Its understated design, low-profile build, and wide compatibility make it an excellent fit for users who value efficiency and clean aesthetics in their systems.
Key Features
The Crucial Pro Series DDR5-6400 kit delivers a speed of 6400MT/s, which provides a clear step up in performance compared to DDR4. This higher transfer rate translates to faster load times, smoother multitasking, and improved responsiveness across a wide variety of applications.
With support for Intel XMP 3.0 and AMD EXPO profiles, the memory can be quickly configured through the BIOS for optimised performance. This dual compatibility ensures users with either Intel or AMD platforms can make full use of the kit without additional tweaking.
The kit includes a secondary profile at 6000MT/s with tighter timings for systems that cannot maintain full stability at 6400MT/s. This fallback option provides flexibility while still offering excellent performance gains over standard memory speeds.
Crucial has designed the modules with low latency, achieving timings of 38-40-40-84 at the rated 6400MT/s. Lower latency contributes to reduced delays when accessing data, which can be especially beneficial in gaming and professional workloads.
Built using Micron’s advanced 1β process technology, the memory benefits from improved efficiency and reliability. This cutting-edge manufacturing process helps ensure consistent performance and stability under heavy use.
The kit is designed with energy efficiency in mind, operating at 1.35V. By keeping power consumption lower, it not only reduces heat output but also contributes to the overall efficiency of the system.
Users can choose between black and white variants, which gives flexibility for custom builds. This small but welcome feature allows the modules to match different themes without sacrificing performance.
The simple, no-frills approach means the memory is focused on functionality rather than aesthetics. For builders who prefer stability, compatibility, and high-speed performance over flashy extras, this kit offers a dependable solution.
