That’s not scaremongering, it’s the truth. I had a 13900K, so I know exactly what I’m talking about.
In any case, the OP has a Ryzen CPU and he can find the initial BIOS settings in the topic linked below. If there’s anything he doesn’t understand, he can ask there.

And if he’s still afraid to set up the BIOS properly, he can invite someone who knows what they’re doing to his home and let that person configure the BIOS and system for gaming, rather than for Solitaire.
