Overview

The Corsair Vengeance RGB CMH64GX5M2B6000C30 is a 2x32GB DDR5 kit running at 6000MHz with CL30-38-38-76 timings at 1.4V. On Intel Z790 and Z690 platforms, that 6000MHz target is a deliberate engineering choice: it sits at the Gear 1 threshold on most boards, keeping the memory controller running in its lowest-latency mode and delivering the full bandwidth Intel's architecture is built around. The CL30 primary timing is acceptable at this frequency but not best-in-class — competitors offer CL28 at 6000MHz for buyers where raw latency is a priority, typically in applications like competitive gaming or rendering pipelines that are directly latency-bound.

The 64GB capacity positions this kit for users who have genuinely exhausted 32GB — content creators managing large Lightroom catalogs, developers running multiple Docker containers or VMs simultaneously, or engineers working with large dataset compilations. The onboard voltage regulation is a functional differentiator rather than a marketing claim: moving the VRM onto the DIMM removes dependence on the motherboard's memory power delivery quality, which varies significantly between boards. Combined with custom XMP 3.0 profile storage in iCUE, this gives more surgical control over the memory subsystem than most DDR5 kits allow. For an Intel 13th or 14th gen build that needs 64GB without compromising memory bandwidth, this kit covers the performance envelope reliably.

Key Features

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.

Create and Customize: Choose from dozens of preset lighting profiles, or create your own in iCUE.

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

Pros & Cons

👍 Pros

  • DDR5-6000 in Gear 1 mode maximizes Intel memory controller bandwidth without the latency penalty of higher-frequency Gear 2 operation
  • 64GB total capacity handles workstation workloads — large RAW photo libraries, multi-VM stacks, and heavy compilation without paging
  • Onboard VRM enables tighter iCUE voltage tuning than motherboard-controlled power delivery, improving overclocking headroom
  • Custom XMP 3.0 profile storage allows saving per-task frequency and timing configurations directly in iCUE
  • Ten individually addressable RGB zones per module diffuse evenly across the panoramic light bar with no dead spots or hotspots

👎 Cons

  • 44mm heat spreader height may conflict with large tower air coolers — verify RAM clearance against your cooler's spec sheet before purchasing
  • CL30 is not tight for DDR5-6000; competing kits achieve CL28 at this frequency, which matters in latency-sensitive workloads
  • Full iCUE RGB and profile features require the iCUE software suite running in the background, adding measurable resource overhead on lean builds
  • Performance advantages over DDR5-5600 are most visible in memory-bandwidth-bound applications; gaming frame rates will see minimal uplift

Frequently Asked Questions

Yes. DDR5 defaults to JEDEC speeds — typically 4800MHz or lower. XMP 3.0 must be enabled in BIOS to unlock the rated 6000MHz CL30 profile. Most Z690 and Z790 motherboards handle this automatically on first boot detection.
For Alder Lake and Raptor Lake, 6000MHz is a well-validated sweet spot. It sits at the Gear 1 boundary on most boards, delivering full memory controller bandwidth. Push past ~6400MHz and many boards shift to Gear 2, widening CPU-to-memory latency in a way that can offset the bandwidth gains.
Not recommended. Adding a second kit from a different purchase batch can cause instability at rated speeds. If you need 128GB, buy a matched quad-stick set from the start rather than pairing two dual-kit purchases.
Yes, measurably. The VRM sits on the DIMM itself rather than relying on the motherboard's memory power delivery, giving iCUE finer voltage step control. This reduces the rail variance that causes high-frequency instability, particularly on boards with less capable onboard memory VRMs.
The LED controller runs independently from the memory bus — RGB management has no impact on memory latency or bandwidth. iCUE does consume a small amount of background CPU and RAM, which is worth noting on systems where every resource counts.
