Corsair Vengeance RGB CMH32GX5M2B6000Z30K

CL30 at 6000MHz works out to 10ns true latency, matching the non-RGB Vengeance kit at the same speed grade exactly, since both use the same 30-36-36-76 secondary timing profile under this B revision code. 6000MHz CL30 is the combination most independent testing points to as the sweet spot for DDR5 right now, and it aligns with AMD's own guidance for running Ryzen's infinity fabric at its most efficient 1:1 ratio.

Because the underlying timings match the non-RGB version of this kit, there is no performance argument for choosing one over the other. The choice comes down entirely to whether RGB lighting and the taller heat spreader that comes with it are worth the premium over the plain version.

DDR5 only, and it will not install in any DDR4 board. Enable XMP 3.0 in BIOS on Intel systems or EXPO on AMD systems to reach the rated 6000MHz; both profiles are stored natively on the module rather than one platform reading the other's data.

6000MHz CL30 is specifically the frequency AMD recommends for the best infinity fabric ratio on Ryzen 7000 and 9000 series, which is the platform this kit is most commonly bought for. On Intel boards it is comfortably within normal XMP support on any board with a decent memory QVL.

The taller RGB heat spreader is the one compatibility factor that doesn't apply to the non-RGB version: check clearance under large tower air coolers before buying, since a light bar sitting roughly 44mm tall can interfere with coolers whose front fan overhangs the first DIMM slot.

Two modules, filling two of four slots on a standard board and leaving room for future expansion, though buying the full capacity you want in one kit rather than adding a second kit later remains the safer route on DDR5, where mixing kits is a more common cause of instability than it was on DDR4.

16GB DDR5 modules at this speed are typically single-rank. Corsair does not publish exact IC supplier or rank guarantees per unit, and either can shift between production runs of the same part number.

The defining feature is the RGB lighting: a panoramic light bar across the top of each module, addressable and controllable through Corsair iCUE, with the option to sync lighting across other Corsair RGB components in the same system. The heat spreader itself is anodized aluminum, consistent with the rest of the Vengeance DDR5 line, but built roughly 44mm tall to accommodate the light bar, compared to the shorter, unlit heat spreader on the plain Vengeance kit at the same speed.

Three colorways are available in this exact speed and CL grade: black, white, and this gray option, which matters if the build is color-matched. Onboard voltage regulation and iCUE's real-time frequency monitoring are present regardless of lighting, same as the rest of the range.

This kit boots at DDR5's JEDEC baseline, typically 4800MHz with loose timings, until XMP or EXPO is enabled. Go into BIOS, select the correct profile for your platform, choose the listed 6000MHz CL30 setting, save, and reboot. Verify the applied speed in CPU-Z or Task Manager afterward.

For nearly all buyers, running the stock EXPO or XMP profile is the intended use case.

Choose that version if RGB isn't a priority; choose this one if it is.

Corsair's own positioning of these two RGB lines describes RGB RS as the accessible tier and this Vengeance RGB line as the higher-performance option, which holds true against this specific CL30 kit as well.

AM5 and recent Intel builds where lighting matters. Full performance of the CL30 tier with the RGB most showcase builds are built around.

Buyers who already run other Corsair RGB components. iCUE sync across the ecosystem is a real, usable feature rather than a marketing line, given Corsair's install base in cases, coolers and fans.

Not for buyers on a tight budget who don't care about lighting. The non-RGB version of this exact kit performs identically for less money.

Not for large air-cooled builds without checking clearance first. At roughly 44mm, this is one of the taller DDR5 kits on the market; measure before buying if a big tower cooler is involved.
