Serial Presence Detect (SPD) is the standard set for a host system to retrieve attributes of memory modules installed on PC. The SPD standard is intended for use on any memory module, independent of memory technology or module form factor.
RAMMon displays the values stored on RAM module such as the memory capacity, the manufacturer, serial number, model part number, the CAS latencies supported and the module voltage. Apart from this, you can also get specific SPD data such as the module thickness, module width, maximum operating temperature and more.
