64GB dual-channel DDR5 kit

This Corsair Vengeance RGB kit delivers 64GB across two 32GB modules for desktop systems. It targets enthusiasts and gamers who need high capacity and speed for demanding workloads or play. The white heat spreader and ten-zone RGB lighting add visual customisation via iCUE software. The kit runs at 6400MT/s with Intel XMP 3.0 support for simple one-click tuning.

CL32 latency at 6400MT/s

The decisive specification is the CAS latency of 32 cycles paired with the 6400MT/s data rate. Timings are set to 32-40-40-40-84 at 1.40V, defining the responsiveness ceiling for memory-sensitive applications. This combination determines whether the kit matches your platform's sweet spot for latency versus bandwidth. Verify motherboard QVL compatibility before purchase.

Thermals and power at 1.40V

The integrated heat spreader manages thermals during sustained high-speed operation at the rated 1.40V. No active cooling is included, so airflow across the modules is required for stable temperatures. Power draw scales with the XMP profile; at stock JEDEC speeds consumption is lower. Fan noise depends entirely on case cooling, not the memory itself.

Questions about this item

What does the DDR5 6400 speed mean once the kit is installed?

The modules run at 6400 MT/s with CL32 timing, delivering PC5 51200 bandwidth when the Intel XMP 3.0 profile is enabled on a compatible motherboard.

What does the Intel XMP 3.0 interface cap in practice?

XMP 3.0 loads the rated 6400 MT/s, CL32 timings and 1.40 V automatically; the motherboard's memory controller and BIOS determine the final stable frequency.

What clearance does the white heatspreader need to fit under a CPU cooler?

The Vengeance RGB modules use a standard-height heatspreader that fits most tower coolers; verify your cooler's RAM clearance spec before ordering.
