Is my 9900K not stable? crash in battlefield 5 without error

Hi my pc.
9900K stock turbo 4.7 . All auto settings in bios. VOLTAGE on AUTO.
Noctua NH-D15 .Temps 60-70C
2x16 GB DDR4 GSKILL 3000 XMP
Corsair 850RmX
Aorus 2080 Ti Xtreme , no oc,stock.

All stress tests passing fine. I dont have any crashes in game.

But few days ago, i go out to work, and i left running game BF 5. When i back,game was running 13 hours,and in 14 hour ( it was 3 am ) it crashed to desktop. Event viewer nothing said. No error message,no display crash. Just exit to desktop.

Game just was on 14 hours,and after moment it go to desktop withour error message. I dont touch anything,game was in campaign mode,when character is standing on the same place.
Now i am testing again and see if i can reproduce, but i cant. I am currently on 80 hour and not crashed again.
Is this reason to worry?My drivers are the newest.
Maybe XMP issue or auto voltage? Or issue with game?

It was a software crash most likely, if you have played it after the crash and it hasn't happened again, I wouldn't worry about it.

Okies so i listen you :) Anyway its fine now. Thx

@sew333:

Run another game and do the test again. Non-ECC RAM wasn't designed for 24h/7d enterprise "always on" usage. https://en.wikipedia.org/wiki/ECC_memory

as others have said: i wouldn't worry about it. chances are it was a software glitch. i doubt EA spent the time needed to harden the game against running for 14 hours straight. its was probably a very hard to reproduce 1 in a million shot bug that wouldn't even be fixed if it was found (unless the fix was simple).

if i was to hazard a guess i would say that the game has a small memory leak and, after 14 hours, the game simply ran out of addressable memory so it crashed.

if the system is generally stable and you can go straight back in and play the game with no issues then i wouldn't be concerned.
