Crucial Pro OC 64GB Kit2 DDR5-6400 U Blk 64 GB (CP2K32G64C40U5B)

The Crucial Pro OC DDR5 64GB 6400MHz (2x32GB) memory kit provides high-frequency DDR5 RAM designed for demanding PC use. With a total capacity of 64 GB across two 32 GB modules and a rated speed of 6400 MHz, this 288-pin DIMM set targets users who require fast, stable memory for multitasking, content creation and gaming. The modules use 1.35 V operating voltage and a CAS latency of 40 to balance speed and stability.

Advantages

Unstoppable speed up to 6,400 MHz reduces latency and can improve frame rates in fast-paced gameplay and other memory‑intensive tasks. The kit supports both Intel XMP 3.0 and AMD EXPO for simplified, stable overclocking and flexibility across next‑generation multi‑core CPUs. Micron engineering and module‑level testing provide component quality and reliability expected from Crucial DRAM products.

Suitable for

• High‑performance gaming PCs running AAA titles
• Workstations for video editing and 3D rendering
• Multitasking systems with heavy memory usage
• Builds that require overclocking with Intel XMP 3.0 or AMD EXPO

How to use

Install each 288‑pin DIMM into matching memory slots on a compatible motherboard following the motherboard manual for dual‑channel configuration. Enable Intel XMP 3.0 or AMD EXPO in the BIOS/UEFI if you want the modules to run at their rated 6400 MHz speed; otherwise they will operate at standard JEDEC speeds. Ensure the system power is off and grounded when handling modules and confirm BIOS settings and stability after first boot.

Recommendations

For best results pair the kit with a compatible next‑gen multi‑core CPU and a motherboard that supports DDR5, Intel XMP 3.0 or AMD EXPO. Run memory stability tests after enabling XMP/EXPO and keep system cooling adequate when overclocking.
