Hi TristanNYC,
I'm facing the exact same issue with a Gigabyte X570 Aorus Pro mainboard, and two MP600. I can't figure out what's going wrong...
Can you explain your Bios solution ? Perhaps a screen capture of the parameter you changed ?
Thanks.
---EDIT----------------
I found a param PCIe Slot Configuration in BIOS that was on Auto, changed it to Gen 4, but had same crash while in a game.
BSOD UNEXPECTED_STORE_EXCEPTION or CRITICAL_PROCESS_DIED
