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 can deliver up to 2x the bandwidth, per an internal simulation of dual ranked x8 modules in client platforms.
3. Only with a DDR5-enabled CPU and motherboard. 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 faster than maximum standard DDR4 speeds of 3200MHz.
5. Crucial DDR5 desktop memory modules (UDIMM) can reach rated speeds with Intel XMP 3.0 or AMD EXPO turned on in the UEFI/BIOS settings. Applicable for all Crucial DDR5 desktop memory (UDIMM) modules except Crucial DDR5-4800 desktop memory, which supports only Intel XMP 3.0. Based on published competitor specs for DDR5 memory as of October 2022. Altering clock frequency or voltage may result in damage to computer components. Micron disclaims any and all liability for such damage. Coverage voided if Crucial DRAM modules are set to overclock beyond JEDEC specifications, rated speeds, and timings.
6. Crucial DDR5 Memory is standard JEDEC memory. Memory speed is not controlled exclusively by the module itself but also by the memory controller in the CPU and the BIOS/firmware on the motherboard. XMP or EXPO support is provided on desktop memory (UDIMM) modules so customers can easily recover memory performance up to JEDEC speeds if experiencing a system-level downclocking of their memory. Performance recovery is not guaranteed on all DDR5 systems and is highly dependent on the CPU tier, motherboard tier, and BIOS stability.
7. Compared to published DDR4-3200 speeds.
8. 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.
