Since the I2C-bus interface supports the SMbus timeout function, it can be used not only for DIMMs, but also to relay the Vital Product Data (VPD) that Solid State Drives (SSDs) requires over the SMbus.

How to view RAM

Webcompatible with modules using SPD devices. In addition, the TSE2002 family of devices is intended to be a superset of the functionality of EE1002 and TS3000 family devices. When writing data to the memory, the SPD inserts an acknowledge bit during the 9th bit time, following the bus master's 8-bit transmission. WebChipset-independent reading and writing of SPD information is done by accessing the memory's EEPROM directly with eeprom programmer hardware and software. A not so common use for old laptops is as generic SMBus readers, as the internal EEPROM on the module can be disabled once the BIOS has read it so the bus is essentially available for use. foam board and batten
