I mean, we used to be able to unlock CPUs by drawing on it with pencil in the right spots...
When you fall for a tech 4chan post that says you can unlock your CPU if you do this one thing to it

It wasn't really even a 'flaw' or 'exploit'. It was more a matter of 'if your chip can handle it, go for it assuming you have good cooling and know what you're doing.
Everything was more or less running at a "safe" speed so that the largest number of chips would be stable at, though it was known to pretty much everone that you could easily overclock for a little more performance.
I mean, there were boards built specifically to overclock, but they were more spendy. Sometimes you could get a cheaper board to overclock with a trick.
It wasn't until overclocking became widespread enough that chipmakers would try to limit it to sell some chips as higher speed and premium pricing. That's when it started getting locked down.
Was a sweet time when you could buy a budget chip that was identical silicon to the faster chips and just tune it to get the same, if not better, performance for cheap.

I remember when it was popular to tell people who got those new-fangled PCI-E cards when they only had AGP slots was to just cut the extra little bit off so it fit properly.
I feel like you could do something like that (I mean make a joke) with how M.2 ssds fit in the motherboard. The last time I read a manual for a PC part was after I got one of those (via recommendation for my build) and was confused where to put it. ๐คฃ
Back in my day we put a bit of nail polish on a couple of contacts on the CPU slot to over-volt it ...
