ECC memory fixes rowhammer. And random bitflips. Everyone should have ECC memory, but Intel disagrees because they are greedy.

My system sometimes detects a few bitflips per day.

There have been demonstrated rowhammer-based ECC bypass attacks. ECC mitigates but does not fix rowhammer.

Perhaps you should replace your RAM, or it's a sign that you have a massive source of radiation lurking somewhere?

I assumed this is just normal in DDR5 and the reason I only had motherboards with ECC to choose from. I do have quite a lot of it.

It wouldn't be the first time engineers pushed something close to the unreliability limit and compensated with a mechanism to make it more reliable.

*nod* I remember an interview with Steve Gibson (author of SpinRite) 10 or 20 years ago where he was talking about how much modern-at-the-time hard drives relied on ECC to reliably achieve higher data densities when it used to be a sign of a drive going bad.
