I'm on Solus 4 Mate, latest updates installed.
Here's my humble hint for more detailed info about RAM such as Timings, Supported CAS Latencies and more.
Install I2C tools for bus detection, chip dumping, EEPROM decoding, display communication and more. It is the EEPROM decoding capabilities that interest me here.
sudo eopkg install i2c-tools
Load, just for this session, the EEPROM kernel module
sudo modprobe eeprom
Decode the eeprom infos and show SPD contents of RAM
If EEPROM decoding is not needed anymore, for the current session, just remove EEPROM kernel module
sudo modprobe -r eeprom
This is a bit of information I have always been looking for, so I share it, hoping it will be useful.
