Not sure why you mention lm_sensors at this point? > I try to get the speed of the RAM using dmidecode but I can't.

If you care about memory speed and don't want to depend on BIOS correctness, then dmidecode isn't the tool you need. What you want is the eeprom kernel driver together with the decode-dimms script from the i2c-tools package [1]. It only works on systems where the SPD EEPROM on the memory modules are exposed on the SMBus though.
