Capacity and audience

This Corsair Vengeance RGB kit delivers 32GB of DDR5 desktop memory across two 16GB modules. It targets Intel 700 Series platform builders who need high-frequency RAM with addressable lighting for a visible system interior. The dual-channel configuration suits gaming rigs and content-creation workstations that benefit from matched pairs. Buyers who want more storage or a different memory generation should look elsewhere.

Speed and timing

The decisive specification is the rated DDR5 6400 speed with CL36-48-48-104 timings at 1.40V, enabled through Intel XMP 3.0 profiles. This frequency and latency combination determines whether the kit matches the memory controller capabilities of your chosen CPU and motherboard. Verify that your platform supports this data rate and voltage before purchasing.

Thermals and power

An integrated black heat spreader covers each module to dissipate heat generated at the 1.40V operating voltage. The ten-zone RGB light bar adds negligible thermal load while drawing power from the DIMM slot. Under normal XMP operation the kit runs within standard DDR5 thermal limits without requiring active airflow directed at the memory slots.

Questions about this item

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

The kit runs at 6400 MT/s when the Intel XMP 3.0 profile is enabled in the BIOS; without it the modules fall back to the standard DDR5 JEDEC speed.

How does the Intel XMP 3.0 profile cap real-world performance?

XMP 3.0 stores the rated 6400 MT/s, CL36 timings and 1.40 V voltage so the memory controller can train once at those settings instead of negotiating lower speeds at every boot.

Will the 288-pin modules with the RGB light bar fit a standard ATX motherboard?

Yes, they use the standard 288-pin DDR5 form factor and a low-profile heat spreader that clears most CPU coolers in a dual-channel layout.
