SPD EEPROM Specification

In addition to the description of the transmission interface, I2C information, the PC SDRAM Serial Presence Detect (SPD) Specification specification defines the information recorded in the EEPROM by the manufacturer. The need for such a specification was caused by the fact that the main problems when installing SDRAM in computer systems are associated with incorrect interaction between the BIOS on the motherboard and the EEPROM on the memory module.

The fact is that many Taiwanese motherboard manufacturers using the Intel 440BX chipset install their own BIOS, which has the function of disabling the reading of information from the EEPROM. In this case, the system parameters are set manually when entering SETUP, or the BIOS itself sets the system parameters for working with standard memory. Continue reading
