That's.....not how non-ECC works. Even a little.

RAM bitflips randomly, period. It's just how it works. A cosmic ray can hit the memory chip just right and flip it, there's no way to predict or control that no matter how "stable" your machine is. ECC still does the same, it just has a parity bit on each line to confirm against and flip it back, as needed.

It is how faulty RAM works, and it is sensible to do that.

Not just faulty RAM. As far as I know, all modern RAM is going to have bitflips every once in a while (it even happens with ECC RAM)

I urge you to educate yourself. All RAM works this way, it's the very reason ECC RAM exists and the exact issue it solves.
