Question Starting to learn how to overclock RAM

The problem with this is I don't know where to start, every time I dig deeper into the subject I find more questions.
I started using the DRAM Calculator to get an idea of what was necessary to put a 3200Mhz CL16 memory into around 3600Mhz CL16 with the same clocks, but then it posed a problem of not knowing the voltage limit on the chip where I can pull it or not or even change it.
In DRAM Calculator I was able to insert the 3600Mhz CL16 memory (I put all the values that appeared there except those that advised me not to touch a video)
without any problems, I played without any type of "crash" and I even had an increase in stability during the game.
What options should be ignored, what should I do if I encounter instability, what should I reduce to do so, things like that only those with experience can answer me.

Despite opening this publication, I already did some research regarding DRAM Calculator and I didn't want to depend on the program since the intention is to gain knowledge and start working on customer machines, and I don't want to depend on a program.

I currently have 2 machines and want to make these changes.
Only my main computer can't do OC on CPU.
Current PC: 5800X3D + Kingston Fury Renegade RGB 64 (2x32GB) 3200MHZ CL16 (I want to OC the RAM to go 3600Mhz CL16 - Stable)
Secondary PC: 5500 + Corsair Vengeance RGB Pro 16GB 3200MHZ ( OC To 3600MHZ CL16-CL18)
 
Don't bother.
Ram chips are binned and the more capable chips will be used in higher speed ram kits that can be sold for more.
Ram faster than stock is already overclocked. You might be able to do a bit more, but don't count on it.

Ryzen depends on fast ram for performance so your thoughts about faster ram are in the right direction.
The way to do that is to sell your current kit ( or keep it as a spare ) and buy a explicitly supported faster kit.

While this may be true with some RAM manufacturers, there are exceptions that could allow someone to:

a) Save $100+ on cheaper RAM that still performs spectacularly if they were reasonably sure what ICs lay under the heat spreader.
b) Get average-priced RAM that supposedly does very well with their particular set up and overclock them substantially with very tight timings, giving superior performance.

Caveat - Memory overclocking, especially when you get into the secondary/tertiary timings, is a VERY deep rabbit hole. There are several wildcards that you just won't really have any control over. Although, there can be a decent difference between tweaked to the hilt overclocked RAM and standard XMP, it will only translate into more than a couple/few FPS in games (and tighter 1% lows) if your RAM was a bottleneck to begin with.
