DDR5 6400 dual-channel kit

This Corsair Vengeance kit provides 32 GB of DDR5 memory across two 16 GB modules running at 6400 MT/s with CL36 timings. It is built for AMD Ryzen platforms and Intel 600, 700 and 800 series chipsets where high bandwidth and low latency matter for gaming and content creation.

Simple slot-in with EXPO or XMP 3.0

The 288-pin DIMMs drop into standard DDR5 slots and expose both AMD EXPO and Intel XMP 3.0 profiles so the rated 6400 speed and 1.35 V voltage apply with one BIOS selection. Problems usually appear only when four populated slots push the memory controller past its comfort zone or when a cooler fouls the low-profile heatspreader.

32 GB headroom for modern workloads

Two 16 GB modules give 32 GB total, enough for current games, streaming and moderate video editing without paging. The CL36 36-48-48-104 timings keep latency tight at 6400, but workloads that regularly exceed 32 GB such as heavy virtualisation or large 3D scenes will need a larger kit or higher-density modules.

Questions about this item

Will this kit run at 6400 speed on my AMD B650 motherboard?

Yes, the kit carries an AMD EXPO profile for 6400 operation on B650, X670, B850 and X870 boards. Enable EXPO in the BIOS to apply the 36-48-48-104 timings at 1.35 V.

Does the white heatspreader clear large CPU air coolers?

The low-profile aluminum spreader is designed for broad cooler compatibility; most tower coolers leave enough clearance for the 288-pin modules.

Can I use only one 16 GB stick instead of the pair?

The kit is validated as a matched dual-channel pair; running a single module will work but you lose the dual-channel bandwidth benefit.
