32GB DDR5 6400 Dual-Channel Kit

This Crucial Pro Overclocking kit delivers 32GB in two 16GB unbuffered DIMMs running at 6400 MT/s with CL38 latency at 1.35V. It is built for desktop systems that support DDR5 memory.

Intel XMP 3.0 and AMD EXPO ready

The modules include both Intel XMP 3.0 and AMD EXPO profiles so the rated speed can be enabled on compatible motherboards without manual tuning. A black aluminium heat spreader helps manage thermals during sustained loads.

6400 MT/s speed decides fit

Your motherboard and CPU must support DDR5 6400 operation either natively or through XMP 3.0 and EXPO profiles. If the platform cannot reach this data rate the kit will fall back to a lower JEDEC speed.
