  • Black heat spreader aids thermal management during sustained loads

Capacity and purpose

This Corsair Vengeance kit provides 64 GB of DDR5 desktop memory in a dual-channel pair of 32 GB modules. It targets high-performance and gaming builds that benefit from large capacity and fast data rates.

DDR5 6400 interface limits

The modules run at DDR5 6400 (PC5 51200) with timings of 32-40-40-84 and a CAS latency of CL32 at 1.40 V. The rated speed and voltage require motherboard and CPU support for the DDR5 6400 data rate; otherwise the kit will operate at the platform's default JEDEC speed.

Compatibility checklist

Verify that your motherboard supports DDR5 memory, 288-pin DIMM slots, and Intel XMP 3.0 profiles for automatic configuration. Confirm the CPU and chipset can handle the 6400 MT/s data rate and 1.40 V operating voltage, and ensure physical clearance for the black heat spreader.

Questions about this item

Should I choose the 64GB dual-channel kit or a different capacity for my build?

This kit provides 64GB total in two 32GB modules running dual-channel, which suits high-performance or gaming workloads on Intel 500 series, 600 series, Z590, Z690 or B660 platforms.

What does the DDR5 6400 speed mean once the memory is installed in my system?

The modules run at 6400 MT/s with timings of 32-40-40-84 at 1.40V, delivering the rated bandwidth when the Intel XMP 3.0 profile is enabled in the BIOS.

Does the 288-pin DDR5 interface limit the 6400 speed in practice?

The 288-pin DDR5 form factor supports the 6400 MT/s data rate and PC5 51200 bandwidth; actual throughput depends on the memory controller and XMP 3.0 profile activation.
