I initially bought this Trident.Z 32GB kit for a 7700K several years ago, and for Hynix it scores pretty well in AIDA64 with optimized timings (over 50K Read/Write, almost 48K copy, at 45ns). I ran a few memory benchmarks and the difference with CAS 14 was in the noise/margin of error, so I don't see much advantage bumping up the voltage unless going for a high score. Even if the added risk is slight, I'm not comfortable leaving it at CAS 14 and 1.43V 24/7, given that the performance gain seems negligible.
It will be a very small difference in performance. To get more performance you really need to push the frequency higher and start tweaking the subtimings, but that's a deep rabbit hole to go down. Probably not worth it for most.

My old Athon 64 X2 3800+ ran with a 2.5GHz overclock (stock is 2GHz) for a decade or so, at lower than default Vcore. Didn't see the point in bumping up Vcore for another 100MHz. The Athlon X2 still runs perfectly...
It's a valid observation. For what it's worth, I'm more on your page. I will not push to extreme voltages for a small gain. I just try to go to the point of diminishing returns and stop there, or even step it back a notch.
