Crucial 64GB 3200MHz Non-ECC Unbuffered DDR4 Laptop Memory Module Faster processing and file manipulation Crucial DDR5 Laptop Memory can empower your computer to transfer data 50% faster than DDR4 at launch, resulting in shorter load times, file transfers, downloads, lag time and improved refresh rates. Due to higher bus efficiency, DDR5 technology is not just faster than the previous generation, its better. Responsive multitasking on the go Crucial DDR5 offers 50% faster speeds than DDR4 at launch, empowering laptop users with extreme performance right out of the box. Even more impressive, Crucial DDR5 Laptop Memory is optimized for enhanced performance and multitasking, not just during testing, but in real-world conditions. Opening more browser tabs and switching between apps now feels more responsive than ever. Improved productivity with innovative channel architecture Significant improvements to DDR5 channel architecture can help you get more work done in less time. With nearly 2x the bandwidth of DDR4, enabled by faster speeds, longer burst lengths, twice the banks and bank groups, two 32-bit channels, and improved refresh schemes, Crucial DDR5 still outperforms DDR4 with higher latency numbers. Optimized power efficiency For improved efficiency and stability, Crucial DDR5 introduces on-module voltage regulation with a power management integrated circuit (PMIC), which was on the motherboard with older memory technologies. This results in improved signaling and cleaner power regulation for the modules (SODIMMs). Moreover, DDR5s on-module operating voltage is only 1.1V compared to DDR4s 1.2V. Micron quality tested reliability you can trust As the vertically integrated consumer brand of Micron, Crucial is trusted by millions for reliability, performance, and compatibility. Unlike module assemblers, our unique relationship with Micron involves a deeper level of engineering collaboration to squeeze every ounce of performance from our products without compromising reliability.
