"Specifically, Nvidia's patch notes state that if 13th/14th Gen CPU owners are experiencing "...stability issues/out of video memory error messages/crash to desktop while the game is compiling shaders..." to consult two sites consisting of an Intel community page and a tutorial from
Rad Game Tools on how to reduce CPU power limits to Intel's default specifications."
It sounds like Nvidia is NOT blaming Intel. They are instructing people to change whatever their motherboard manufacturer has set BACK to Intel's default specifications.
They are kind of saying that overclocking, either by the consumer or motherboard manufacturer isn't guaranteed stable.
If I overclock my CPU and it crashes then it isn't stable and I dial it back. What has changed now is that motherboard manufacturers are overclocking the CPU as their stock bios settings and this is starting to be a problem for some. It is still the same principal, just somebody else has done it to your CPU so you may not be aware.
I also undervolt my 13900kf while raising the clocks. I also run 2nd or 3rd from the lowest vdroop LLC. With an undervolt the power consumption isn't terrible even with a high power LLC.
I haven't had these issues, but I imagine that is mostly because I am one of the lucky majority. Something about these chips is that the higher the temps, the more volts they need to stay stable at a given clock. If that given clock only has enough volts to be stable at 80c, and it needs more volts per temp increase than the temp volt curve gives it then it will crash at 100c. Also if the LLC is set too low and a very high power draw causes the volts to dip below stability then the system will crash when the volts supplied to the CPU drop below what is stable for the clocks and the temp the CPU is at. The answer for both problems is unfortunately more volts, better cooling, or lower clocks. You could also use a thermal velocity boost overclock that also reduces the clocks at high temps, but does so automatically. These are compromises that have to be made if you are overclocking these chips.
It's a shame that many motherboard manufacturers are tossing people into the tuning is required boat when they buy an i9 by pre overclocking their systems and not telling them.
For example my lowly Asus Prime Z690 P increased my P-core clocks by 100 mhz as stock. Where I get 5.5 all core and 5.8 for 2 cores at any temperature and thermal velocity boost gives me 200mhz more below 70c at stock, if enabled. They also have multicore enhancement enabled by default and I have to select the enforce Intel's limits option manually. The MCE dumps a lot of extra power into my CPU and makes it unmanageable for my D15 cooler under all core heavy loads. It also runs my memory controller at over 1.5v at stock per HWinfo. An ordinary person might think that everything the motherboard does is guaranteed stable by Intel so they should just be able to reset their bios and have their i9 be stable. But it is overclocked by default. And overclocks are not guaranteed stable.
And the i7s and i5s get a different treatment. They don't have the volt curves run as high into the exponential area and the users have to set the higher volts themselves or they just get a crash from not enough volts when they are overclocking. But they are stable under full load because they get a more traditional treatment.
For 12th-14th gen, it seems i9s are commonly pre overclocked by the motherboards and lower SKUs are OC'd less if at all. I don't think that Intel's standard settings for i9s are unstable, just the motherboard standards sometimes are.
