bdiefinder VS cylon.js

check this and this and aim for a b-die only kit

You can check on this side : https://benzhaomin.github.io/bdiefinder/

Your kit is not listed here and 18-22-22-42 is untypical for b-die. Altest for the good bins.

I can get my hands on F4-4000C19D-32GTZR. According to b-die finder it is b-die. Will I be able to max out the performance on a 5900x? Is there a difference on kits that run on 1.35V vs 1.5V ? Can I just increase the voltage to 1.5V and reduce timings and frequency? AFAIK 4000Mhz is not possible or not recommended on ryzen because of the 2:1 fclk. Should I buy it or try to find something else?

That kit is indeed b-die. here

Use Samsung b die finder to check SKU, but good rule of thumb is if the frequency is 3200+ and timings are flat (e.g. 16-16-16-34 or 19-19-19-39) most likely it’s bdie. I don’t think patriot sells any 2x16GB kits. I know OLOY and Gskill have some around the $250-275 dollar range. If you aren’t running itx mobo you might just go 4x8GB to save some money.

Absolutely. Just enter the exact model under the link I have earlier: https://benzhaomin.github.io/bdiefinder/

Trident Z memory, only get it if it's listed in the B-Die Finder because then those sticks will be great for overclocking. If not, just stick with Crucial Ballistix.

As a general purpose language, it can be used for other things like desktop applications, robotics, and even an emulation of an operating system that runs in a web browser. However, these uses are much less common than its main usage, which is still for the "front-end" of a web page or web application.
