Corsair Vengeance RGB RS CMG64GX5M2D6000Z40 (64GB 2x32GB Kit/DDR5 6000MHz/CL40/1.35V/RGB Anodized Aluminium Grey/Intel XMP 3.0 + AMD EXPO) Review
The Corsair Vengeance RGB RS CMG64GX5M2D6000Z40 is the RGB RS line's high-capacity option: 64GB (2x32GB) at 6000MHz CL40, the value tier's answer to buyers who need 64GB without paying for the standard Vengeance RGB line's tighter timings. Corsair's own comparison of its two RGB DDR5 lines specifically notes that RGB RS launched with 32GB and 64GB capacities first, aimed at the price-sensitive segment of the market, which is exactly the role this SKU fills.
CL40 is the loosest primary timing covered anywhere in this product family, which is the trade this kit makes deliberately: capacity and price over latency.
Performance and Timings
CL40 at 6000MHz gives roughly 13.3ns true latency, the loosest figure in this entire family of Corsair DDR5 kits, and looser than the 64GB CL32 kit at 6400MHz by a meaningful margin. Still, this kit hits 6000MHz, the frequency AMD recommends for Ryzen's fabric ratio, and for a genuinely capacity-bound workload, having 64GB at CL40 will outperform a 32GB kit at any CL grade the moment the workload actually needs more than 32GB of working memory.
Compatibility
DDR5 only. Enable XMP 3.0 on Intel or EXPO on AMD to reach 6000MHz. As a two-module 64GB kit, this is generally easier for a board's memory controller to run stably than a four-module 64GB configuration would be, but check the board's QVL for 32GB-per-module support specifically, since not every board that handles smaller-capacity DDR5 modules cleanly is validated for 32GB sticks.
Module Count and Rank
Two 32GB modules. Buy the full 64GB needed in this one matched kit rather than combining two 32GB kits bought separately later.
Design and Build
Standard RGB RS heat spreader and lighting design, grey finish, motherboard-native RGB compatibility reducing the need for a dedicated Corsair app. Scaled to 32GB per module rather than a different physical design from the smaller-capacity RGB RS kits in the line.
Overclocking and BIOS Setup
Boots at JEDEC baseline until XMP or EXPO is enabled. Select the correct profile, choose 6000MHz CL40, save, reboot, verify in CPU-Z.
Comparison to Sibling Products
Against the 64GB CL32 6400MHz kit in the standard Vengeance RGB line, this trades a genuine latency and frequency gap for a lower price at the same capacity, the clearest value-versus-performance choice in this entire family. Against the 32GB RGB RS kits at 6000MHz, this simply doubles capacity at a broadly similar per-module timing profile.
Who This Kit Is Actually For
Budget-conscious buyers who specifically need 64GB. The cheapest route to that capacity within Corsair's RGB DDR5 range.
Not for anyone latency-sensitive. CL40 is the loosest timing in this product family; buyers who care about latency at 64GB should look at the standard Vengeance RGB 64GB CL32 kit instead.
Not for buyers who don't actually need 64GB. For most gaming and general use, a 32GB kit at a tighter CL grade will be both cheaper and just as fast in practice.
