Corsair Vengeance DDR5-6800 2x16GB

This Vengeance family runs considerably faster than the entry DDR5 grade Corsair sells under the same name, at 6800 MT/s and a matching CL40 across both listings — the timing doesn't split here the way it does in some of the brand's other ranges.

Capacity is the real variable: 2×16GB kits sit alongside a larger build reaching 32GB, so a buyer choosing within this family is deciding on total size and channel population rather than speed. Four-module configurations put more load on a memory controller than two larger sticks at the same total, worth weighing if you're filling every slot on your board.

As UDIMM, it needs a desktop board rated for 6800 MT/s-class DDR5 to actually hit that number — a board that only supports lower speeds will still run it, just at a reduced rate.
