Intel says the 9900k VCore limit is 1.52V?

Here's the sticks I'm running.

Thanks I was able to get up to my RAM up to 3700MHz stable at 1.37V with those timings, and I'm running my CPU 5.3GHz at 1.39V

Glad you got it going. Stable is key. Matters most.

I’m not looking to compete for records in any way, I just want to try and get the best possible performance and stability using the most ideal settings. These days is using Intels XTU considered the same or as good as tuning in the UEFI/BIOS?

Quite frankly, overclocking isn't really much helpful to get more frames, that's what I've found out. I don't know about you, for me, I just do that out of curiosity.
I have built a new rig recently, a 9600K not really a superb CPU but I've done research prior to getting it. Also, I planned on what I use it for before buying it. The clock frequency in real world turns out to be higher than the figure on Intel's paper (ark.com) and I count that as a plus to my original expectations. I did overclock it on my ASUS mobo, but that's only for a few times and each time no longer than an hour. Besides, I was doing that according to the mobo's auto overclock utility lest manual overclock will damage the chip. My point is the longevity of the chip.

If I had a 9900K, I wouldn't overclock it, first because it's being pricy, second it's already the fastest as far as games are concerned.

That's just my personal opinion.

That's a nice result, well played

Depends, especially in terms of gaming because that is a realtime workload so every 100 mhz is a few frames and with higher clocks, a higher RAM freq also pays off again. But, that isn't much different than it'd be on a 9600K. Put differently, if you get these K CPUs and DON'T overclock them, why even bother / waste the money? There are far better offerings in that case, like most Ryzen CPUs that run lower temp and auto OC out of the box with XFR and come with a heatsink.

About chip longevity; you can easily run your 9600K at 1.3~1.4V 24/7 and it'd last 8-10 years no issue. Don't worry too much and get those damn tools out already! Lifespan decreases happen at very high voltages and very high temps (throttle territory), which I'd say is beyond 1.4V. 1.52 might be a safe max but its really quite high, also for the board, traces etc.

He also has an RX 570 he would probably have to run 640x480 low settings to see a gain.

Max under full current load is somewhere around 1.42v @80c, the 1.52v is the maximum peak voltage that may result from transients due to current load changes. The voltage regulator on the motherboard is not capable of adjusting current quick enough, so if the CPU goes from a high current to a low current, there will be a voltage spike.
