B450M Steel Legend - BIOS reset when active XMP

Hello, now in January I bought a new PC, but I have a problem, when raising the frequency or activating XMP (16-18-18-36@1.35V), a few days later the BIOS is reset.
I did stress tests with AIDA and I had no problem. My memory is Samsung B-die.

I configured the timings manually and I also had the same problem.

The BIOS is updated to the latest version (2.90). I put the memories in slots A2-B2.

My setup:
AMD Ryzen 5 3600X | Asrock B450M Steel Legend | Adata XPG Spectrix D41 TUF 2x8GB DDR4 3000Mhz | MSI GTX 1050 AERO ITX | Corsair CX-430W | DeepCool Gammaxx GTE

its telling you it cant run the ram at 3200 with the timings the ram wants to set
either run ram at 2933
or
follow the settings from the free software called ryzen dram calculator for safe 3200

more detailed answer
your cpu although very able really cannot control the ram at the timings set by the motherboard based on the rams SPD data
it probably could with just 2 sticks but 4 sticks is much extra strain on mem controller

the real issue is the bios isnt making the best choice/guess for some of the ram timings and thuis its crapping out on boot test and resetting to defaults

if you manually enter the timings from the ryzen calculator it 'should' be able to handle them
