Crucial 16GB DDR5 4800MHz CL40 Desktop RAM (CT16G48C40U5)

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.

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.

1. 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.
2. 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.
3. Computer must have a DDR5-enabled CPU and motherboard. Crucial DDR5 Desktop Memory is not compatible with DDR4 motherboards.
4. 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.
5. DDR5 launch data rate of 4800MHz transfers 1.5x (50%) more data than the maximum standard DDR4 data rate of 3200MHz.
6. 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.
7. 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.
