Corsair VENGEANCE DDR5 CUDIMM: The Complete Guide

The release announced “the immediate availability of its VENGEANCE RGB DDR5 CUDIMM memory kits”, said the non-RGB versions would ship “in the first week of December”, and promised “even faster kits arriving soon” 1. Of the four Corsair product pages checked for this guide, three are 48GB two-module kits at 8400, 8800 and 9200MT/s 234, and one is a 96GB four-module kit at 7000MT/s, below the release’s 8400MT/s starting point 51. Corsair does not date that kit 5.

The release’s headline is “CORSAIR VENGEANCE RGB DDR5 CUDIMMs Deliver Cutting-Edge Performance with a Bold, Modern Aesthetic”, and its body says the lineup “begins with the release of the VENGEANCE RGB DDR5 CUDIMM” 1. It carries a Milpitas, CA dateline and quotes no named person 1. Corsair’s product pages call the two lines VENGEANCE RGB DDR5 CUDIMM and VENGEANCE DDR5 CUDIMM in their Memory Series field 35.

The release says the RGB modules have a “mirrored silver finish” and that “Ten individually addressable RGB LEDs” sit under “a panoramic light bar that extends to the module’s edges” 1. The RGB product page says “ten individually addressable, ultra-bright RGB LEDs per module” 3. All four product pages list Heat Spreader Aluminum, Memory Color SILVER and PMIC Type or Power Draw “Extreme OC PMIC” 2345. None of the four lists a module height 2345.

Every kit lists SPD Voltage 1.1V and Performance Profile Intel XMP 5234. Corsair writes SPD speed in MHz and tested speed in MT/s or as a bare number; this table copies its wording 54.

The release says the modules are “built using hand-sorted, tightly screened memory chips” without naming whose 1. It explains that CUDIMMs “include a Clock Driver IC” (CKD) that regenerates and amplifies the clock signal 1. Corsair’s explainer describes the CKD as a buffer “for the clock signals sent from the CPU to the memory module” 6.

The release says the CUDIMMs are “optimized for the latest Intel Core Ultra 200-series processors and Z890 motherboards” and that a compatible platform such as those “is required” to unlock their full potential 1. Each product page says “Optimized for Intel® 800 Series or newer motherboards” and lists Memory Compatibility “Intel 800 Series” 5234. Profiles are Intel XMP 3.0 1; none of the four product pages mentions AMD EXPO 5234.

The release has an “Availability, Warranty and Pricing” heading but states no price 1. When checked, the three US product pages’ price data showed $969.99 for the 48GB 9200MT/s kit, $1,120.99 for the RGB 48GB 8800MT/s kit and $1,199.99 for the 96GB 7000MT/s kit 435. These are point-in-time store prices, not launch prices.

The explainer shows a figure captioned as a CORSAIR CUDIMM “running at 9,600MT/s” on Intel® Z890, a speed above every kit checked here 6. The release says the kits are “backed by a limited lifetime warranty” 1, and each product page carries the heading “LIMITED LIFETIME WARRANTY” 5234.

The release says the RGB CUDIMMs “stand out from previous VENGEANCE DDR5 offerings with a sleek mirrored silver finish” 1. The explainer says that until now the fastest DDR5 UDIMMs “could reach 8,000MT/s” with a good CPU and a high-end dual-DIMM board 6. None of the Corsair sources checked names a successor 16.

The release says CUDIMMs “are compatible with existing DDR5 architectures and platforms” “when used in Bypass mode, operating like traditional UDIMMs” and mentions “backward compatibility with previous DDR5 platforms”, with no speed figure for that case 1. The explainer says they are “backwards compatible (at 6,000MT/s or below) with previously available DDR5 platforms”, elsewhere that “speeds may be limited to 6,000MT/s”, and that on an AMD platform “they tolerate the use of it by operating in Bypass mode only” 6. The four product pages list Memory Compatibility “Intel 800 Series” and mention neither Bypass mode nor AMD 5234. The release never mentions AMD 1. These statements do not contradict one another; they differ in detail, and only the explainer, which carries no date, gives the 6,000MT/s figure 6.
