You don't get a popup. In Linux, it's logged in dmesg. In Windows I imagine it goes in the system log. The system keeps on running. The value of the notification is that if most days you get nothing and suddenly 5000 corrected errors pop up, you know something is not quite right as of late. Maybe you're overdoing the overclocking. Maybe the module isn't sitting quite well in the slot. Maybe a solder joint is failing. If you have a 2 bit memory error, the typical result is a BSOD/kernel oops. Which is a good thing actually. It means you know for sure your RAM is bad, and it prevents any faulty data from being written anywhere. So rather than possibly propagating the error is just stopped. I believe there have been systems that try to handle it more elegantly. Kill the process the memory belongs to if it's a non-essential one then permanently blacklist that block to ensure it's not used again.
