CAS Latency|Color CL40|Gray Dual

  • 64 GB total capacity from two 32 GB modules
  • DDR5 5600 speed rated at PC5 44800 bandwidth
  • CL40 CAS latency with 40-44-44-90 timing profile
  • 25 V operating voltage for efficient power draw
  • AMD EXPO and Intel XMP 3.0 profiles for automatic configuration

64 GB dual-channel DDR5 kit

This 64 GB kit contains two 32 GB modules built for desktop systems that support DDR5. It targets users who need high capacity for content creation, heavy multitasking or gaming on modern AMD and Intel platforms.

CL40 latency at DDR5 5600

The modules run at DDR5 5600 with a CAS latency of CL40 and timings of 40-44-44-90. This latency figure is the primary spec that determines whether the kit matches your CPU and motherboard requirements.

Low voltage with integrated heat spreader

Operating at 1.25 V, the memory draws modest power for its speed class. The aluminium heat spreader dissipates heat quietly without active cooling, keeping thermals stable during sustained workloads.

Questions about this item

How does the DDR5 5600 speed with CL40 latency affect real-world desktop performance?

At 5600 MT/s and CL40 the modules deliver high data throughput for multi-core CPUs, reducing render and compile times while the low 1.25 V voltage keeps thermals manageable.

What does the PC5 44800 label tell me about the memory interface and its practical limit?

PC5 44800 identifies the DDR5 5600 transfer rate; the dual-channel kit reaches that speed when the motherboard enables the XMP 3.0 or EXPO profile.

Will the gray heat-spreader modules fit a standard 288-pin DDR5 slot without clearance issues?

Yes, the 288-pin DIMMs use a low-profile Vengeance heat spreader designed to clear most CPU coolers in a typical ATX build.
