people forget, blowing up AM5 cpus wasn't just as Asus thing... they were just the most ham-handed with the voltages. Everyone was operating out of spec, there were chips that blew up on MSI and Gigabyte boards, and it wasn't just X3D either.
Intel is no different - nobody enforces the power limit out of the box, and XMP will happily punch voltages up to levels that result in eventual degradation/electromigration of processors (on the order of years). Every enthusiast knows that CPU failures are "rare" and yet either has had some, or knows someone who's had some in their immediate circles. Because XMP actually has caused non-trivial degradation even on most DDR4 platforms.
In fact it's entirely possible that this is an electromigration issue right here too - notice how this affects some 13700Ks and 13900Ks too? Those chips have been run for a year or two now. And if the processors were marginal to begin with, and operated at out-of-spec voltages (intentionally or not)... they could be starting to wear out a little bit under the heaviest loads. Or the memory controllers could be starting to lose stability at the highest clocks (under the heaviest loads). That's a thing that's not uncommon on 7nm and 5nm tier nodes.
