On my 2600x I couldnt even match stock clock/voltage manually never mind an o/c, AMD really got the most out of these chips out the factory, to me when they aggressively tuned out of the box it is a good thing, I have never been a fan of silicon lotteries (I guess because I usually lose them).
Also with multiple overclocked or undervolted chips I have seen chips been stable for many years under windows, no BSOD, no WHEA errors etc. then boot up linux on them and sudden page faults or segfaults that go away when the chip is put back to stock, for whatever reason windows seems more lenient on unstable setups, and I do wonder how many overclocked systems out there are actually not 100%.
The latest example is my 2600x was undervolted and ran windows fine for years, I have now repurposed it as a proxmox hypervisor and was getting random pagefaults during p-state transitions, when I removed the undervolt its been fine since.
