***FIXED*** I will edit if I get a crash again but I have been playing all day no crash. Prior to this I couldn't make it an hour without a crash.

This may only be a fix for Ryzen. I enabled PBO in BIOS , selected thge Positive curve option under curve optimizer, and set the magnitude setting to 5. I left the clock setting at +0. I have not had any issues in other games so I am not sure if my CPU just has a bad core or what that final fantasy is exposing, but this fixed it for me. Do this at your own risk. I would not increase the voltage much on your CPU. I believe that increasing it to 5 on my bios increased the max mv by .025.
