64GB DDR5 6400 Dual-Channel Kit

This Crucial Pro Overclocking kit delivers 64GB of DDR5 memory across two 32GB modules. It runs at 6400 MT/s with a CAS latency of CL40 and operates at 1.35V. The white aluminium heat spreader helps manage thermals during sustained loads.

Intel XMP 3.0 and AMD EXPO Profiles

The modules support both Intel XMP 3.0 and AMD EXPO for one-click overclocking on compatible platforms. Builders who cannot enable these profiles or who need ECC or registered DIMMs should consider other kits. The dual-channel layout suits mainstream desktop boards with four slots.

DDR5 6400 CL40 at 1.35V

The decisive specification is the DDR5 6400 speed rated at CL40 latency with a 1.35V operating voltage. This combination determines whether the memory matches the motherboard's qualified-vendor list and the CPU's supported memory-controller limits.
