Also, you need to be the administrator to run the software.īy default on certain platforms (such as ASUS), the BIOS disables SPD Writes which prevents access to the SPD raw data on the module.Īlthough no actual writes are performed on the SPD, SMBus write operations are required to access the full 1024 SPD bytes. (The SMBus is the low speed circuit on the motherboard that connections the CPU to various other components on the motherboard and it is used to transfer the PSD data from a RAM stick to the CPU). On other machines it might not be possible to locate the SMBus on these machines to collect the RAM's SPD data. On these systems the soldered chips might not contain any SPD data, as the corresponding data, that would be in the SPD, is hard coded into the BIOS on the machine instead. Some laptops use RAM soldered to the motherboard (as opposed to being in a socket). This includes some systems from Dell, HP, ASUS & Lenovo. Some system vendors ship non standard systems, especially for Laptops. Such as the module thickness, module width, maximum operating temperature and more. RAMMon displays the values stored on RAM module such as the memory capacity, the manufactuer, serial number, model part number, the CAS latencies supported and the module voltage.Īlso, depending on your RAM type, other specific SPD data can be retreived as well.

The SPD standard is intended for use on any memory module, independent of memory technology or module form factor.

Serial Presence Detect (SPD) is the standard set forth by JEDEC for a host system to retrieve attributes of memory modules. This information provides a snapshot of the available data for each RAM module installed on the system. It uses SysInfo DLL SDK to gather the SPD attributes from RAM devices. It will allow users to identify a multitude of attributes, of which, includes the manufacturer, the clockspeed and other data of their DDR2, DDR3, DDR4, DDR5, XMP and EPP memory devices and even some older memory types. RAMMon is an easy to use Windows based application that allows users to quickly retrieve the Serial Presence Detect (SPD) data from their RAM modules.
