Crucial CT64G56C46U5 DDR5-5600 64GB (1x64GB)

Manufacturer: Crucial

The Crucial CT64G56C46U5 DDR5-5600 is a high-capacity memory module offering 64GB of storage in a single stick. It operates at a speed of 5600 MHz, providing ample bandwidth for demanding applications.

This DDR5 memory features a CAS latency of 46 and runs at a voltage of 1.1V. With timings of 46-46-45-45 (CL-tRCD-tRP-tRAS), it offers reliable performance without integrated heatsinks or RGB lighting, and it supports Intel XMP 3.0 for overclocking.

Pros
  • Supports Intel XMP 3.0 for easy overclocking and performance tuning.
  • Single 64GB module allows for high-capacity memory expansion in systems with limited slots.
  • Operates at a relatively low voltage of 1.1V, which can contribute to better energy efficiency.
Cons
  • Does not support ECC memory, limiting its use in error-correcting applications.
  • Lacks an integrated heatsink, potentially leading to higher temperatures under heavy workloads.
  • No RGB lighting, which may be a downside for users seeking aesthetic customization.
  • Does not feature Samsung B-Die, which could be a drawback for enthusiasts looking for specific memory chips for overclocking.
Who is this for?

This product is ideal for users who need a high-capacity memory solution with 64GB of total memory in a single module. Its support for Intel XMP 3.0 also makes it suitable for enthusiasts or power users looking to overclock their system for improved performance.
