The DIMM SPD memory contains information about the memory module such as size, serial 

number, data width, speed/timing, voltage and thermal information. This information is written by 

the module manufacturer and stored on an EEPROM. This EEPROM cannot be written to when 

the memory module is installed in a PC. Third party tools do exist that can write to the EEPROM 

when the memory module is not installed in a PC. There are various third party tools available to 

read SPD memory.
