The instructions below are not exactly complicated, but they are time consuming and could take 1-2 days to complete if you don't find errors on the first diagnostic tests.
Download and install Memtest86 to a USB drive. Set the USB drive as UEFI boot in the bios and manually set the ram to 2133mhz with 15-15-15-36 timings and 1.2v, then save and exit. Let it boot to the USB drive to run the default automatic test. If you get any errors, stop the test by shutting down the system. Take one module out and run the test again. If you get errors again try your other 2 slots with both modules and repeat the testing. If you still get errors, send the ram back for replacement or refund it to buy something else.
If you don't get any errors, install the modules back to slots A2/B2. Manually set the ram to 3600Mhz with timings 18-22-22-42 and voltage to 1.35, then run the test again. If you don't get any errors after 2'ish hours of testing, you should let memtest86 run all 4 passes which will take around 4-5 hours in total. If you get no errors, use the system until you get a BSOD or a program crashes, then increase voltage to 1.36-1.37 and try testing again. If it still crashes, reduce the speed to 2933/3000 or 3200Mhz and try testing again. If you can successfully complete a 4 pass test, don't get a BSOD or programs don't crash at either 2933/3000 or 3200, the system should be stable by this point, so you can try tighter timings like 16-18-18-38 or leave it alone.
If you you still get crashes from 2933-3600mhz, send the ram back and get a different kit. Sometimes up to 1.4v can make cheaper kits run more stable, but if it can't even work at or near the advertised specs, it's not worth keeping unless the platform itself can't actually run the speed. An X570 motherboard and Ryzen 3000 should be able to run at least 3733Mhz
