Hi my pc.

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 100 hour and not crashed again.




It happened once after 14 hours be in game.

Somebody said:" "Try to slightly increase your DRAM Voltage (something between +0,015v and +0,050v)! I would bet that the problem is solved after that. I saw a few users before having exact the same problem with the Hero XI and G.Skill Ram as u. Please inform us if it worked!"






But i run memtest86 8.2 for 4 passes no errors, and RAM TEST overnight no errors.

So wait, this whole snipe hunt is as a result of an error occurring in a game? Nothing else? Come on, you have got to be kidding. An invalid pointer is a bug in the game, not a hardware problem! Oh, and "Somebody" doesn't have a clue what he's talking about and you really shouldn't be listening to them.


Just saying,
