Memory OC can brick the game, happened with me 2 times.
So to the OP: don’t be a dick, it is very possible, that even the normal XMP settings are causing problems. Try with default, then increase the ram speed, and lower the timings for yourself until it’s fine.
Memtests, stresstests can pass without a single error, but when it comes to CE, even the otherwise atom stable memory settings can bring this game to its knees.
