Vengeance 32GB DDR5 6400 Kit

This dual-channel kit provides 32GB of DDR5 memory in two 16GB modules rated at 6400 MT/s with CL30 timings. It targets enthusiasts building or upgrading Intel 600 or 700 series and AMD 600 or 800 series platforms for gaming or high-performance workloads.

Platform and Profile Check

Verify that your motherboard supports DDR5 288-pin modules and can enable either AMD EXPO or Intel XMP 3.0 profiles to reach the rated speed and timings. Confirm the board has two available slots and that the CPU memory controller can handle the 1.40V operating voltage.

Thermals and Power Profile

The black aluminum heat spreader dissipates heat from the tightly screened ICs and onboard voltage regulation during sustained loads. At stock settings the kit runs at 1.40V with CL30-40-40-104 timings, so typical power draw remains modest and fan noise is determined by your case airflow rather than the modules themselves.

Questions about this item

Will this kit fit my motherboard that has four DDR5 slots?

The kit contains two 288-pin DDR5 modules, each 16 GB for 32 GB total, so it occupies two of the four slots and leaves two free.

Can I run the rated 6400 MT/s speed without manual BIOS tuning?

Yes, the modules carry both AMD EXPO and Intel XMP 3.0 profiles; enable the appropriate profile in BIOS to reach DDR5 6400 CL30 at 1.40 V.

Is the memory compatible with AMD 600-series and Intel 700-series chipsets?

The specifications list AMD 600, 800, B550, B650, B850, X670, X870 and Intel 600, 700 series as recommended platforms.
