Corsair Vengeance DDR5-5600 2x32GB

The desktop side of Corsair's Vengeance DDR5 range sells each speed grade at one fixed clock and lets capacity vary instead, from a modest pair of small sticks up to sets built for boards meant to run a full complement of memory.

2×32GB of DDR5 UDIMM gives 64GB in this listing, rated at this grade's 5600 MT/s CL40 — the practical question is less about speed, since every kit in the grade shares it, and more about whether your board and use case call for two populated slots or four. That rated speed still needs EXPO or XMP selected in firmware to be reached, on standard desktop boards built for unbuffered, non-ECC memory like the rest of Corsair's mainstream Vengeance line.
