Memory module Corsair DDR5 64 GB 6400 MHz

The Corsair CMT64GX5M4B6400C32 is a 64 GB DDR5 memory kit (4 x 16 GB) with a 6400 MHz clock speed and CL32 latency, built on a 288‑pin DIMM form factor. Designed for high-performance PCs, this module improves multitasking, gaming, and content-creation workflows by delivering faster data transfer and higher bandwidth compared with previous-generation memory.

Advantages

DDR5 technology provides higher frequencies and greater capacities for enhanced throughput. Onboard voltage regulation allows finer control and more stable overclocking when used with compatible software. Integrated RGB lighting can be synchronized via iCUE for cohesive system aesthetics, and support for Intel XMP 3.0 (custom profiles via iCUE) simplifies applying optimized performance settings.

Suitable for

• High-end gaming PCs
• Content creation and video editing workstations
• Multitasking and heavy productivity setups (many tabs, virtual machines)
• Systems requiring large memory capacity for professional applications

How to use

Install the modules into the DDR5-compatible DIMM slots on a supported motherboard following the motherboard manual for correct slot population. Enable the desired Intel XMP 3.0 profile in the BIOS or use Corsair iCUE software to load custom profiles and adjust voltage regulation settings. Ensure the system is powered off and unplugged during installation and re-check seating before booting.

Recommendations

Use this memory kit with motherboards and CPUs that explicitly support DDR5 and 6400 MHz operation. For stable overclocking, update motherboard BIOS to the latest version and configure voltage and timing changes incrementally. Synchronize RGB lighting through Corsair iCUE to maintain consistent system illumination.
