Overview

The Corsair Vengeance RGB DDR5 CMH32GX5M2B6400C36 is a 32GB dual-channel memory kit running at 6400 MHz with a tested latency of CL36-48-48-104 at 1.35V. It is engineered to take full advantage of Intel's DDR5 platform, delivering the higher bandwidth and greater capacity that DDR5 brings to demanding workloads like gaming, video editing, 3D rendering, and heavy multitasking. The kit's Intel XMP 3.0 support means you can enable its rated speeds with a single BIOS toggle, while Corsair's iCUE software unlocks deeper control — including the ability to create, customize, and save your own XMP profiles tailored to specific applications or tasks, as well as real-time monitoring of frequency and onboard voltage regulation for more precise overclocking.

Visually, the Vengeance RGB DDR5 stands out with ten individually addressable RGB LED zones per module, housed in a panoramic light bar that disperses color evenly and remains visible from multiple angles inside a windowed case. Corsair offers dozens of preset lighting profiles through iCUE, with full support for synchronization across other Corsair RGB peripherals and components. Beyond aesthetics, the modules are built with a custom PCB designed for signal integrity at high frequencies, contributing to the stable operation that DDR5 overclocking demands. For builders on the latest Intel platform who want both strong memory performance and a polished visual presentation, this kit covers both requirements in a single package.

Key Features

Disclaimer: Maximum Speed requires overclocking/PC BIOS adjustments. Maximum speed and performance depend on system components, including motherboard and CPU

Dynamic Ten-Zone RGB Lighting: Illuminate your system with ten individually addressable, ultra-bright RGB LEDs per module, encased in a panoramic light bar for vivid RGB lighting from any viewing angle.

Onboard Voltage Regulation: Enables easier, more finely-tuned, and more stable overclocking through CORSAIR iCUE software than previous generation motherboard control.

Custom Intel XMP 3.0 Profiles: Customize and save your own XMP profiles via iCUE to tailor performance by app or task for greater efficiency.

Maximum Bandwidth and Tight Response Times: Optimized for peak performance on the latest Intel DDR5 motherboards.

Pros & Cons

👍 Pros

  • DDR5-6400 speed with CL36 latency delivers strong bandwidth for gaming and productivity workloads
  • Ten-zone individually addressable RGB LEDs per module provide vivid, customizable lighting from any angle
  • Onboard voltage regulation through iCUE allows finer overclocking control than motherboard-only adjustments
  • Custom Intel XMP 3.0 profiles let you save and switch between tuned settings for different tasks
  • Dual-channel 2x16GB configuration balances capacity and compatibility for most desktop builds

👎 Cons

  • Optimized specifically for Intel platforms, limiting full feature support on AMD DDR5 systems
  • 1.35V operating voltage is above the DDR5 baseline of 1.1V, drawing slightly more power
  • Requires Corsair iCUE software to access advanced features like custom XMP profiles and voltage control
  • Panoramic light bar adds height to the modules, which may cause clearance issues with large tower CPU coolers
  • Higher price point compared to non-RGB DDR5 kits at the same speed and capacity

Frequently Asked Questions

This kit is optimized for Intel DDR5 motherboards with Intel XMP 3.0 support. While it may physically work in AMD DDR5 boards, the XMP 3.0 profiles and iCUE voltage regulation features are designed for Intel platforms.
CL36 at 6400 MHz represents a tight latency-to-speed ratio for DDR5, meaning the memory responds quickly relative to its high clock speed. This translates to snappier performance in gaming, content creation, and multitasking compared to higher-latency DDR5 kits at the same frequency.
No, the RAM functions at its rated speeds using standard XMP 3.0 profiles activated through your motherboard BIOS. iCUE is optional and provides additional features like RGB lighting customization, real-time frequency monitoring, and the ability to create custom XMP profiles.
The kit includes two 16GB modules for a total of 32GB, configured for dual-channel operation.
The ten-zone RGB LEDs draw minimal power and do not produce meaningful heat. They have no measurable impact on memory temperatures or performance.
