There's no guarantee that it works with standard clocked memory either.

Both AMD and Intel publish on their site, for each CPU model, the maximum supported memory speed.
If the CPU does not work at that speed, you are entitled to a replacement or a refund.
For instance, AMD Ryzen™ 9 9950X3D is guaranteed to work with DDR5-5600, but with nothing faster. No AMD non-server CPU goes above this limit for DDR5.
Some of the Intel CPUs are guaranteed to work with faster memories, e.g. Core Ultra 9 285K with up to DDR5-6400, and the very recently launched Core Ultra 7 270K PLUS with up to DDR5-7200.
