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.
