go-edac is a golang library and utility for Linux kernel Error Detection and Correction (EDAC).
go get -u github.com/multiplay/go-edac
In order for EDAC information to be available your system needs the required kernel modules installed and loaded.
The following command will return as list of modules if they are:
lsmod |grep edac
If you don't see any modules and you have a CPU which supports ECC memory checking, you may need a newer kernel which adds support for your specific hardware.
For example Ubuntu 16.04 LTS GA Kernel (4.4) only supports up to Intel E3-1200 v5 CPU's.
If you want to stick with 16.04 LTS and have a newer Intel CPU you can opt into the Rolling HWE Stacks
apt-get install --install-recommends linux-generic-hwe-16.04
This will update your kernel to 4.15 which supports up to the 7th Generation Intel E3's.
