7 / 56 page - 7 - datasheet DDR3 SDRAM Rev. 1.3 Registered DIMM 5. Pin Description NOTE : * The VDD and VDDQ pins are tied common to a single power-plane on these designs. 6. ON DIMM Thermal Sensor SCL SDA WP/EVENT SA0 SA1 SA2 SA0 SA1 SA2 EVENT R1 0 Ω R2 0 Ω NOTE : 1. All Samsung RDIMM support Thermal sensor on DIMM 2. When the SPD and the thermal sensor are placed on the module, R1 is placed but R2 is not. When only the SPD is placed on the module, R2 is placed but R1 is not.
