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...

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 https://youtu.be/vvZA9n3e5pc?t=1193
