I recently upgraded to Ryzen platform. I used default settings in the BIOS and I tried to turned on XMP to get 3200Mhz.
I noticed my games are crashing, freezing and sometimes I get BSOD. But when I changed it to default 2133Mhz, everything is fine.
I read somewhere that you have to manually set the timings, increase/decrease voltage or overclock your CPU. I am scare to overclock my CPU but it would be nice to get the maximum 3200Mhz for my RAM.
I use Ryzen 7 2700X, Gigabyte Aorus X470 Ultra Gaming and GSKILL TRIDENTZ (2X8GB) 3200Mhz.
