A server with 64 GB of ECC ram sitting at an altitude of 3.2 km on the Greenland ice sheet is reporting... 0 bit errors (whether correctable or uncorrectable) in the 244 days it's been up.

A server with 16 GB of ECC ram at an altitude of 3.8 km in California is reporting.... 0 bit errors in the 146 days it's been up.

Maybe I shouldn't believe what /sys/devices/system/edac/mc is reporting? These are EL8 systems...

Bryan Cantrill mentions in this talk that they saw no correctable errors, until they suddenly got uncorrectable errors. Turns out that the firmware was hiding the fact that it had been correcting ECC errors the whole time. https://youtu.be/vvZA9n3e5pc?t=1193
