The game really exposes unstable CPU and GPU overclocks FYI. More so that benchmarking in things like Cinebench and 3d mark.Never had one crash in 100s of hours of gameplay mate. I've never clocked my pc since I built it, this is the first one I've never clocked. Never had a pc run so problem free in any game.
I had many crashes when attempting CPU overclocking and GPU overclocking / undervolting. Also using Geforce experience with sharpening filters would crash after ~20 minutes. Undervolting the GPU also was not great and caused a couple of full system shutdowns, I expect it needed to boost and hit higher voltages but couldnt.
I run overclocked RAM now (3600MHz C16 @3800MHz C14) but stock 5800X and stock 3080FE. The temps on my 3080FE are low and never go about 66c playing Warzone. I do however lock FPS to 97 and play at 3440 x 1440, maxed setings expect DOF and blur things.
Here's my full Warzone settings
