Find out RAM timings (like CAS) and manufacturer on Ubuntu
I honestly don’t know how this works, but got it from this SO answer. (The only one that worked for me.)
sudo apt install i2c-tools
sudo modprobe eeprom
sudo modprobe at24
sudo modprobe i2c-i801
sudo modprobe i2c-amd-mp2-pci
sudo modprobe ee1004
decode-dimms
P.S. Probably the same on Debian.
