Hi pc:

13900K stock
2x16 GB DDR5 GSKILL 6800
Rtx 4090 Gigabyte Gaming
Aorus Elite Z790 AX
SSD KINGSTON 2TB
Seasonic 1300W PX ATX 3.0 PCIE 5.
win 11

Each new install of nvidia drivers, and launching Remnant 2 ( the same UE5 engine like Lords OTF ), then on first launch ,during shader compilating it throws OUT OF VIDEO MEMORY and it can BSOD.

Next launches are fine.Just on first launch of the game, during first compiling shaders.

The same thing happened on game Lords of The Fallen, on first launch during shader compilating. And next launches are fine.

But like i said it will bsod again if i install new drivers and launch game for first time.

And third game. Hogwart Legacy. ( no bsods,but CTD on that three times ).

Today i upgraded drivers to 545.92 for Alan Wake 2. And launched for first time Hogwart Legacy on newest drivers. It crashed three times to dekstop when i launched. Just before shader compilating crashed two times,and one time at shader compile. On fourth try i was able to run game,and now is launching fine everytime. Why i had that three crashes on boot? Is my cpu not stable?.

Also. I tested by Karhu Ram test no errors. Cinebench R23 passing. All games are stable beside that. Prime95 Small FT stable no errors.

Should i change ram,cpu or what is your opinion? Thx
