I have no issues running COD MW Multiplayer with my stock GPU settings.

You got lucky my friend!!!
It's not a big of a deal, I don't have crashes every time I play but go to Reddit and you will see the huge amount of problems people have. There is even reports of fried cpu because of the Dev Error 6068 crashes.
With my OC I can play every game without a single problem for more than 4 hours straight (The Division 2, Metro: Exodus, The Witcher 3, Wolfenstein: Youngblood, ...) so CoD is not an example for stability and OP shouldn't worry about if it crashes or not. The strange thing is the problems OP have with 3dmark

i know this is old, but (may be a trigger for some) in regards to crashes..?

never have i had any crashes on this card, other than when i was initally setting up my overclock. or when the mb had the ram xmp profiles backwards for some reason and i left frequency to 3800mhz at cl16, yes this KHX3466C16D4/8GX kit will run at 3800 mhz on ryzen at cl19 speeds stable. anyhow, hows your card doing now? still crashing? or
