Having the same issue.
Everything was fine a few months ago before I paused playing for a few months. Then sometime after Season 1 the game crashes itself and even my PC sometimes out of nowhere.
My specs:
i9-9900K
ASUS STRIX RTX 2080 ti
ASUS Z390-F
64 GB Crucial Ballistix RAM
850W bequiet PSU
I have 4x16 GB RAM (set to 3600 MHz). I already tried changing the slots, but that only seemed to work for like ~3 matches. It crashed again while I was playing the 4th match, if I remember correctly.
Edit: After setting the BCLK frequency to 100:133 in BIOS (default was 100:100) it seems to work fine for now. I also set the RAM frequency back to 3600 MHz. Because once you change BCLK, it defaults the RAM frequency. So it is 100:133 at 3600 MHz now.
I shouldn't have to do this. Nobody should have to do this. I don't even really know what it does. And I don't know if it is advisable to do this. But it works... for now.
Edit 2: I changed my mind and instead just set the MHz to auto (which is 2666 MHz in my case) and changed the BCLK frequency back to 100:100.
No crashes so far after 2 weeks of playing.
Fix your game DICE.
