I was able to run stable 3466mhz at stock settings. Whenever I change the timings system reboots eventually.

Any BSOD? Do you know if your PC is stable at 3600 Mhz with other RAM? Is your Fclock able to run 1800 Mhz and not cause any WHEA 19 errors? Hwinfo64 should show those. Event viewer does too, if you filter the log.
UserBenchmark doesn't tell me anything. It is all over the place. Only thing it is good for is components of your system, if you don't know what you have. But even then, there are other programs.

Never had BSOD on this PC. 3600mhz is the sweet spot for Ryzen 9 and 1800mhz Fclock is ideal recommended by AMD.

Sounds like the company line. Imagine us being on a steamtrain, in the front, driving the train. The train comes to a sudden unexpected halt and I ask you: "Why are we stopping? Did you check that we have enough coal burning? Did you check that we are not overheating?". And your answer is: "This Northern Traveler line of trains can do 80 km/h when the wind is in the back. It is in their commercials".
Yes, yes, it can. But currently, we are not moving at all. We are stuck here unless you check exactly why the train stopped.
