I fixed mine!!! let me explain...

So I recently came back to the game a couple weeks ago and its been hell, id say I could play maybe 30 mins maximum before a DirectX crash, although often it was much sooner, maybe 10-15 mins before I would get a crash or even a PC lockup. Now everyday ive been searching for answers! ive looked a in a fair few places and tried a lot of whats been recommended here and elsewhere, stuff like...

- Completely removing drivers and doing a fresh install
- Fresh install of the game
- Removed background apps/startup apps
- Run in windowed fullscreen
- Running in DX9
- Removing any OC's, Undervolting

and nothing fixed the issue. The last error I got was...

An unexpected error has occurred. Exiting FINAL FANTASY XIV. 2022-01-24_23:58

I remember reading somewhere about RAM, what if RAM was the issue, which at first made no sense to me because DirectX is a graphics thing right... but hey, thought id give the RAM a test and see if she is all good. I ran the Windows Memory Diagnostic and sure enough failures, a few actually. Was weird so I ran MemTest, sure enough failures. Mind you up until now my PC has been fine, maybe an odd hold up here or there but nothing too weird.

Decided to buy some new RAM, I had those sticks since 2017, at the very least it would remove any failures I have currently. Put the RAM in today (its the same Size 32GB 3600 C18) and ran the tests again, both came back fine, 0 failures. Opened up FFXIV and that was 8 hours ago, its still running fine...

So it might not help everyone but it helped me, test your memory. I literally changed NOTHING!!! since the last crashes apart from RAM, no settings changes, no updates, nothing.

The weirdest part is FFXIV was the only game or application to give me any kind of errors or crashes, nothing else, yet my RAM was reporting failures... My PC was perfectly normal in my eyes until I had the failures reported. So I would recommend even if your PC seems fine, run the tests, it cant hurt to check.

I hope I could help someone else, oh by the way my PC specs are as follows...

- Nvidia 3090
- Intel i5 12600KF
- Gigabyte Z690 Gaming X
- G.Skill Trident Z Neo 32GB 3600C18 DDR4 (previously Corsair Vengeance Pro 32GB 3600C18 DDR4)
