CAS Latency CL46

  • 128 GB dual-channel kit enables heavy multitasking and large-project workflows
  • DDR5 5600 speed with CL46 latency delivers high bandwidth for demanding applications
  • 10 V operation reduces power draw while maintaining 5600 MT/s performance
  • Intel XMP 3.0 and AMD EXPO profiles give one-click optimised settings on supported platforms
  • Black heat spreader aids thermal management during sustained workloads

128GB DDR5 5600 dual-channel kit

This Crucial Pro kit delivers 128GB across two 64GB unbuffered DDR5 modules rated at 5600 MT/s with CL46 latency and 1.10V operation. It includes Intel XMP 3.0 and AMD EXPO profiles for automatic configuration on supporting platforms. A black heat spreader is fitted to each module.

Suited to high-capacity desktop workloads

The 128GB capacity serves users running virtual machines, large-scale rendering, heavy multitasking or memory-bound data workloads. Builders who need ECC error correction, registered modules or lower-density kits should look at other products.

64GB per module density

Each stick provides 64GB in a single rank, a density that requires a motherboard and CPU memory controller validated for 64GB DDR5 modules. Verify that your platform supports this module density before purchase.

Questions about this item

Will this kit run at 5600 MHz on a board that only supports 5200 MHz or 4800 MHz?

The modules downclock automatically to the highest speed the platform allows, so they operate at 5200 MHz or 4800 MHz if the system cannot run 5600 MHz.

Does the kit need XMP 3.0 or EXPO enabled in the BIOS to reach 5600 MHz?

Yes, the rated 5600 MHz speed requires enabling the Intel XMP 3.0 or AMD EXPO profile in the BIOS; otherwise the modules run at the platform default speed.

Is this memory compatible with a Ryzen 7000 Series desktop CPU?

The kit is designed for 12th Gen Intel Core or Ryzen 7000 Series and newer desktop processors.
