What kind of configuration data is stored on the DIMM Serial Presence Detect (SPD) memory
module? How would this data be written?
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.
