My setup is:
ASUS TUF B450M-Pro Gaming (BIOS ver. 2006, latest)
Ryzen 7 2700x
HyperX Predator DDR4 PC4-25600 HX432C16PB3K2/16 - 2 kits with 2 sticks each
When I'm using D.O.C.P. profile in BIOS for 3200mhz (16-18-18 timings, 1.35v) system becomes highly unstable, frequent BSODs, memory errors (15 of them at least; checking with Ryzen DRAM Calculator, Default preset). But with profile for 3000 mhz (15-17-17 timings) it gets a lot better (0 memory erros, although still BSODs happen once/twice per day).
How can I make it run without problems on 3200? Or is there hardware problem with mobo or RAM, how can I check it?
Final update:
If someone will stumble upon the same problem:
I've replaced motherboard to MSI X570-A Pro, RAM now working at XMP profile 2 (3200mhz) right from the box, without any additional tweaks involved. No BSOD's or errors in memtest (ryzen DRAM calculator).
