Vengeance DDR5 6400 dual-channel kit

This Corsair Vengeance kit provides 32GB of DDR5 memory in two 16GB modules rated at 6400 MT/s with CL32 timings. It runs at 1.35V and includes both AMD EXPO and Intel XMP 3.0 profiles for automatic configuration. A white aluminium heatspreader covers each module.

Suited to AMD 600, 800 series and Intel 600, 700.

The kit is validated for AMD B650, X670, B850 and X870 platforms as well as recent Intel chipsets. Builders using older DDR5 platforms without EXPO or XMP 3.0 support will not reach the rated speed. Systems requiring four populated slots should consider a four-module kit instead.

Deciding spec: DDR5 6400 CL32 at 1.35V

The memory operates at 6400 MT/s with a 32-40-40-40-84 timing set at 1.35V. If your motherboard and CPU combination cannot sustain this data rate at the stated latency and voltage, the modules will fall back to a lower JEDEC speed. Verify platform support for 6400 MT/s before purchase.

Questions about this item

Will this kit run at 6400 on a Ryzen CPU with a B650 board?

The modules are rated DDR5 6400 CL32 at 1.35V and carry AMD EXPO profiles. A Ryzen CPU on a B650 motherboard can load that profile in the BIOS, provided the BIOS version supports EXPO and the memory controller is stable at that frequency.

Does the 32-40-40-40-84 timing affect stability at 6400?

Those are the validated timings for the rated speed. Running at the XMP or EXPO profile applies them automatically. If the system posts but shows errors, lowering the frequency or loosening the timings in the BIOS usually restores stability.

Will the white heatspreader clear a large air cooler?

The Vengeance modules use a low-profile aluminium heatspreader designed for broad cooler compatibility. Most tower coolers leave enough clearance, but checking the cooler’s specified RAM height limit against the module’s physical height is the only way to be certain.
