All computer DDR memory today have little I2C EEPROMs to store vendor, configuration and module spec information. This is done to allow computer to detect memory type, and configure memory interface to correct speeds and voltages according to module spec. This mechanism is based on JEDEC Serial presence detection specification (SPD) which is available for
