Corsair Vengeance CMK64GX5M2B5600C40 (64GB 2x32GB Kit/DDR5 5600MHz/CL40/1.25V/No RGB Anodized Aluminium/Intel XMP 3.0) Review
Corsair Vengeance CMK64GX5M2B5600C40 is a 64GB (2x32GB) DDR5-5600 CL40 dual-channel kit with no RGB lighting, black anodized aluminium heat spreader, Intel XMP 3.0.
A more budget-friendly 64GB Vengeance DDR5 option running the looser JEDEC-adjacent CL40 timing at the same 5600MHz frequency, this kit trims cost for buyers who need the capacity more than the last bit of latency. It's a sensible choice for a workstation or server-adjacent build where raw memory bandwidth for multitasking matters more than gaming-grade responsiveness.
Why Buy It
CL40 at 5600MHz trades some latency for a lower price than the CL36 version of this same kit, appealing to buyers who prioritize hitting 64GB affordably over squeezing out every bit of responsiveness.
Comparison to Alternatives
It's the budget-timed sibling of the Corsair Vengeance CMK64GX5M2B5600C36 also being added, offering identical capacity and frequency at a looser, cheaper CAS latency.
