Empower your next-generation, multi-core CPU Crucial DDR5 Desktop Memory has the high speed needed for the next generation of multi-core CPUs, but it’s not just faster than DDR4, it’s better¹. Multitask seamlessly, load, analyze, edit, and render faster — all with higher frame rates, significantly less lag, and optimized power efficiency over the previous generation². With Crucial DDR5 Desktop Memory, your computer³ can harness blazing speeds that were once only possible with extreme performance memory⁴.

Faster load times and file transfers Crucial DDR5 Desktop Memory can empower your computer to transfer 50% more data than DDR4 at launch, resulting in faster load times, file transfers, downloads, refresh rates and less lag time⁵. Due to higher bus efficiency, DDR5 technology is not just faster than the previous generation, it’s better¹.

More responsive multitasking Crucial DDR5 offers 50% faster speeds than DDR4 at launch⁴, empowering users with extreme performance right out of the box. Even more impressive, Crucial DDR5 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.

Extreme innovation for stable performance Crucial DDR5 takes an extreme step forward in engineering over the previous generation with two independent 32-bit channels per module for optimized performance⁶. Designed with on-die ECC (ODECC)⁷ at the component level for long-term stability, Crucial DDR5 is engineered to maintain the same reliability as the previous generation, even with the rigorous demands of next-gen computing.

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 technologies⁶. This results in improved signaling and cleaner power for the modules (DIMMs). Moreover, DDR5’s on-module operating voltage is only 1.1V compared to DDR4’s 1.2V.

Micron X Crucial — quality and 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 that delivers powerful performance you can trust. When it comes to memory, don’t settle for less.

DDR5 architecture includes efficiency improvements that deliver 36% more system bandwidth than DDR4, even at the same theoretical speeds of 3200MHz, due to the high bus efficiency of DDR5 technology. Combined with lower voltage per module, this design provides superior (better) performance.Under memory-intensive workloads, DDR5 delivers 1.87x the bandwidth as a result of double burst length, double the banks and bank groups, and significantly higher speed than DDR4. It is enabled to support scaling memory performance with improved channel efficiency, even at higher speeds, not just during testing, but under real-world condition, as established by JEDEC, an independent standardization body that develops open standards for the microelectronics industry.Computer must have a DDR5-enabled CPU and motherboard. Crucial DDR5 Desktop Memory is not compatible with DDR4 motherboards.DDR5 launch speeds of 4800MHz are comparable to extreme-performance DDR4 memory speeds and are 1.5x (50%) faster than maximum standard DDR4 speeds of 3200MHz. DDR5 launch speeds of 4800MHz delivers 1.87x the bandwidth of the maximum standard DDR4 speeds of 3200MHz.DDR5 launch data rate of 4800MHz transfers 1.5x (50%) more data than the maximum standard DDR4 data rate of 3200MHz.DDR5 modules (DIMMs) introduce voltage regulation on the module through a power management integrated circuit (PMIC), which enables better power regulation and reduces the scope of DRAM power delivery network (PDN) management on the motherboard for increased efficiency.Crucial DDR5 Desktop Memory is non-ECC memory. The ECC as it pertains to RDIMMs, LRDIMMs, ECC UDIMMs and ECC SODIMMs is a function that requires additional DRAM at the module level so that platforms, such as servers and workstations, can correct for errors on individual modules (DIMMs). On-die ECC (ODECC), however, is a feature of the DDR5 component specification and should not be confused with the module-level ECC feature. Crucial DDR5 Desktop Memory is built with DDR5 components that include ODECC, however these modules do not include the additional components necessary for system level ECC.
