Corsair Vengeance DDR5-7000 2x16GB CL40

Toward the top of Corsair's Vengeance DDR5 range, every kit in this speed grade shares the same rated clock, and it's timings and capacity that separate one listing from the next. This is one of the faster fixed-speed grades the line is sold at, sitting above the mid-range Vengeance kits.

7000 MT/s is constant across this grade, but CL40 spans a noticeably wide window — a tightly binned kit and a loosely binned one can carry the same headline speed while behaving differently under load. Capacity ranges from smaller kits up to considerably larger sets sold as 2×16GB, and reaching 7000 MT/s on a board with four populated slots is generally harder on the memory controller than a two-slot dual-channel setup.

All of it is unbuffered, non-ECC UDIMM for desktop boards, and needs the XMP profile enabled to hit its rated speed rather than the slower JEDEC default it ships at out of the box.
