Corsair Vengeance CMK32GX5M2B6000Z30

CL30 at 6000MHz gives a true latency of exactly 10ns, calculated as CAS latency divided by half the rated speed. That places this kit at the tight end of mainstream DDR5, ahead of the CL36 and CL38 kits in Corsair's own lineup at the same 6000MHz speed, and it is why this specific speed and CAS combination is the one most reviewers point to when asked "what DDR5 kit should I buy."

The secondary timings, 30-36-36-76, are the standard profile Corsair ships across the B-revision 6000MHz CL30 family regardless of color or lighting, so this kit performs identically to its RGB siblings at the same speed grade. The only real-world difference between this kit and a CL36 kit at the same frequency is a few percent in memory-latency-sensitive workloads and a marginal frame-rate gain in CPU-bound games at 1080p. In GPU-bound gaming and in most productivity work, the difference all but disappears.

This is a DDR5 kit and only fits DDR5 motherboards; it does not physically or electrically work in any DDR4 board. On Intel systems, enable XMP 3.0 in BIOS to reach 6000MHz. On AMD boards, enable EXPO instead, Corsair's own EXPO profile, not a re-read of the Intel XMP data, so both native profiles are stored on the module rather than one being emulated.

6000MHz is the frequency AMD explicitly recommends for Ryzen 7000 and 9000 series to keep the infinity fabric clock running 1:1 with memory, which is the main reason this speed and CL grade is the most commonly recommended DDR5 kit for AM5 builds specifically. On Intel 12th to 14th generation and Core Ultra 200 boards, 6000 CL30 is comfortably within normal XMP support on any board with a reasonable memory QVL entry.

Check your specific board's QVL before buying, particularly on boards running four DIMM slots at full capacity, where DDR5 kits are generally less forgiving than DDR4 was about running all four slots at their rated speed.

This is a two-module kit filling two of typically four slots on a standard ATX board. DDR5 in particular benefits from running as a two-stick kit rather than four sticks of a smaller capacity, since DDR5's on-module power management and higher operating frequencies make four-DIMM configurations considerably harder to stabilise at full rated speed than they were on DDR4.

16GB modules at this speed are commonly single-rank, though Corsair does not guarantee a specific rank or IC supplier from the model number alone, and it can shift between production runs. Do not plan to add a second identical kit later to reach 64GB; buy the full capacity you want in one matched kit, since mixing kits bought separately, even under the same part number, is a common source of DDR5 boot instability.

This is the non-RGB Vengeance DDR5 design: a compact anodized aluminum heat spreader with no lighting bar, finished in a single gray colorway. Compared to the RGB Vengeance line at the same speed grade, the non-RGB heat spreader sits noticeably shorter, which is the main practical advantage if clearance under a large tower air cooler or a case with a tight side panel is a concern.

Onboard voltage regulation is present regardless of the lighting variant, and iCUE can still read frequency and voltage in real time and save custom profiles even without RGB hardware to control. The build otherwise matches the rest of the Vengeance DDR5 range: hand-screened ICs, a high-performance PCB for signal integrity, and Corsair's limited lifetime warranty.

Like all DDR5 modules, this kit boots at a JEDEC baseline well below its rated speed, generally 4800MHz with loose timings, until a profile is enabled. Enter BIOS, select XMP on Intel boards or EXPO on AMD boards, choose the listed 6000MHz CL30 profile, save, and reboot. Confirm the reported speed in CPU-Z or Task Manager to verify it actually applied.

Beyond enabling XMP or EXPO, further manual tuning is possible through iCUE's onboard voltage regulation, but headroom varies by IC batch and is not something Corsair discloses per unit.

Within Corsair's own DDR5 lineup, the closest sibling is the RGB version of this exact speed and CL grade, the Vengeance RGB 32GB 6000MHz CL30 kit, which uses the same 30-36-36-76 timings and voltage but adds a taller heat spreader with per-module RGB lighting controlled through iCUE. Choose this non-RGB kit if cooler clearance or a plain aesthetic matters more than lighting; choose the RGB version if it doesn't.

Corsair's own comparison of the two RGB lines describes RGB RS as the accessible tier and standard Vengeance RGB as the higher-performance tier, and the same relationship broadly holds against this non-RGB CL30 kit: it sits above the RS-tier CL36/CL38 kits in raw latency and below Corsair's premium Dominator line in price and finish.

AM5 Ryzen builders. 6000MHz is the frequency AMD itself points to for the best fabric-to-memory ratio, and CL30 is the tight end of what's available at that speed.

Intel builders who want the best mainstream DDR5 timing without paying for RGB.

Small form factor and large air-cooler builds. The non-RGB heat spreader clears more coolers than the taller RGB variant at the same speed.

Not for buyers who want lighting. If RGB matters, the RGB version of this exact kit exists at the same timings for a premium.

Not for anyone chasing maximum capacity. This is a 32GB kit; buyers who need 64GB should look at Corsair's higher-capacity kits directly rather than doubling up on this one later.
