Crucial DDR5 Desktop Memory. Not just faster. Better.
Crucial DDR5 Desktop Memory - 2 modules
  • Speed: up to 5,600MT/s
  • Voltage: 1.1V
  • Technology: DDR5
  • Densities: 8, 16 and 32GB
  • Form Factor: UDIMM

Empower your next-generation, multi-core CPU

Crucial DDR5 Memory has the blazing speed and massive bandwidth needed for the next generation of multi-core CPUs¹. Multitask better, load, analyze, edit, and render faster, game with higher frame rates and significantly reduce system lag for heavy workloads over the previous generation². With Crucial DDR5 Memory, harness performance that was once only possible with extreme performance memory³.

Extreme performance right out-of-the-box

Crucial DDR5 Memory can transfer data up to 1.75x faster and deliver up to 2x more bandwidth than DDR4, resulting in shorter load times, file transfers, downloads, lag time and improved refresh rates. Performance is enhanced not just during testing, but in real-world conditions².

Best value with support for both Intel XMP 3.0 and AMD EXPO

Even with CPUs that suppress memory speed, Crucial DDR5 desktop memory can reach its rated speeds with Intel XMP 3.0 or AMD EXPO turned on in the UEFI/BIOS settings⁴. Get the full value of your investment without overpaying for performance and enjoy the flexibility of using your Crucial DDR5 Desktop Memory in either an Intel or AMD build⁵.

No latency downsides with DDR5

Crucial DDR5’s system latency, measured in nanoseconds, is only up to 3% longer than DDR4 during testing⁶, meaning real-world latency performances are virtually the same. With Crucial DDR5 delivering up to 2x more bandwidth, DDR4 is still outperformed.

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 technologies⁷. 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.

Crucial DDR5 desktop memory - Micron Quality

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. Only with a DDR5-enabled CPU and motherboard. DDR5 desktop memory is not compatible with DDR4 motherboards.
  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. DDR5 4,800MT/s speeds are comparable to extreme-performance DDR4 memory speeds and 1.5x faster than maximum standard DDR4 speeds of 3200MT/s.
  4. Crucial DDR5 desktop memory modules (UDIMMs) 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 beyond JEDEC specifications may result in damage to computer components. Coverage voided if Crucial DRAM modules are set to overclock beyond JEDEC specifications, rated speeds, and timings. Micron disclaims any and all liability for such damage.
  5. 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.
  6. Compared to published DDR4-3200 speeds.
  7. 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.

Suitable for my Lenovo Legion
I wanted to upgrade my Lenovo Legion since I got only 1 stick of 16GB (made by Micron). This one work perfectly with the one I already had, both sticks are now working together in dual channel at CL36 4400MHz. Great catch for the price!
