Anyone in these comments claiming there is a big difference between “gaming distros” and any other is flat wrong.
Any distro works. It’s about the initial experience they want without having to fuss about changes. You can switch Desktop Environment on any distro easily, none of them offer massive gaming performance differences over the others. It’s subjective. For a beginner, don’t recommend immutable. That’s pretty much it.











If the RAM timings are not exactly the same, you’re going to have instability issues. This is why it’s always recommended to install pairs of the same exact model and brand, the clock timings.
I doubt that BIOS is going to give you the specs you need, but somewhere you’ll likely be able to find the timings and compatible memory for this machine. You’ll generally need something faster than what’s installed so it can step it’s timings down to be more in sync.
