I'm actually building pc now with these

Ryzen 5 5600g
Asus tuf b450m plus II
Teamgroup T-Force Vulcan Tuf 3600mhz 8x2
Tecware Forge M2 case
Msi Mag 550w 80+ bronze
Tammuz ssd 128gb
Seagate hdd 1tb

so my question is bout this ram. It's unusual because its timings is off the chart. I mean even the QVL of motherboard, I don't actually see it.

The timing is 19-19-19-39
Cas Latency 39
Voltage 1.35v

Educate me pls. What to do? What to change? Enable for me to draw out the best performance I could get. Thanks!

QVL lists are a snapshot in time. Motherboard manufacturers don't continually update them.
Unless you have already done other tweaks, I would leave RAM timing to the last couple % of improvement.

Based on timings, you have CAS Latency of 19 and not 39.

What exactly you are asking? Highest frequency your RAM can do? Want to tighten the timings? Lower voltage?
Also, what frequency you're running, stable?

Btw, according to the RAM specs,

19-19-19-39 are normal timings for it @ 3600 Mhz. Sure, they are quite loose with high CAS Latency, but that's what cheap RAM is. Tighter timings with lower CAS Latency RAM costs more to make and in turn, also costs more to buy.
For example:
Your RAM costs 62 bucks in amazon: https://www.amazon.com/TEAMGROUP-T-Force-Alliance-3000MHz-PC4-24000/dp/B08MF31FSZ
While same speed and amount of RAM, but with CL16, costs 82 bucks, amazon: https://www.amazon.com/Crucial-Ballistix-Desktop-Gaming-BL2K8G36C16U4B/dp/B083V93HJG

can I adjust it?
Yes, you can. This is called manual OC.

If the OC isn't stable, system doesn't boot and you'd be back in BIOS, or it reverts to JEDEC default (usually 2133 Mhz).

You can tighten the timings, by one or two values. E.g 18-18-18-37. If it doesn't hold at 3600 Mhz with 1.35V, you may need to lower the frequency or increase voltage. Now, frequency lowering is safe but you need to be very careful with voltage increases since you can fry the RAM if you feed too much voltage to it. 1.4V is max safe voltage for DDR4.

Here's nice, short vid about manual RAM OC;
