Crucial CB16GU4800.C8AT 16GB Review

The Crucial CB16GU4800.C8AT is a 16GB DDR5-4800 desktop memory module rated CL40 at 1.1V, for a true latency of 16.7ns.

We'd point budget builders here first, it's the cheapest legitimate way to put genuine Crucial-quality DDR5 in a desktop build, provided you don't need XMP or a matched dual-channel kit.

Performance

4800MT/s CL40 is DDR5's un-tuned floor, true latency around 16.7ns, this is the value tier Crucial sells below its mainstream CT-series and Pro line. AM5 boards will happily run it at this speed since it's well under the 6000MT/s 1:1 fabric sweet spot.

Comparison to Alternatives

Crucial's own CT8G48C40U5.M4A1 uses the same 4800MT/s CL40 spec at half the capacity for buyers only needing 8GB.
