What the UA batch numbers for these two 3700X's?
Let's face it, 3000 was basically a beta test for AMD's chiplet design (of which Ryzen 5000 is the finished product), and AMD treated its product and us buyers as such. It wouldn't be surprising to start seeing more stability issues with time, from some of the initial lower binned CPUs / harder-worked CPUs. 3600 and 3700X got the worse end of the stick - there were some
really bad 3600s and 3700Xs in Q2 2019 and Q3 2019 production - like, 4.0 @ 1.3V bad.
AMD definitely pushed more Vcore through the 3000 chips than 5000. Probably in a bid to try to get the lower quality silicon as close to the "rated boost" as they could get, to avoid a class action lawsuit. I got used to seeing peak Vcore at up to 1.55V every other day on my 3700X for a meagre 4.28GHz effective, no PBO no offset no nothing just bone stock - and the same on 4 different motherboards, no less. The 5900X now peaks at about 1.49-1.5V @ 4.85-4.9GHz effective, stock.
The I/O die says hi and would like to remind that it too is a piece of silicon with finite lifespan

in all seriousness, the entirety of my old chip was a [barely] living testament to "if it ain't broke, don't fix it" - read: don't overclock a turd

So I learned my lesson and not fixing what's not broke is what I'm doing now
