3 / 18 page  Rev. 1.3 Aug. 2005 256MB, 512MB Registered DIMMs DDR2 SDRAM Pin Configurations (Front side/Back side) NC = No Connect, RFU = Reserved for Future Use 1. RESET (Pin 18) is connected to both OE of PLL and Reset of register. 2. The Test pin (Pin 102) is reserved for bus analysis probes and is not connected on normal memory modules (DIMMs) 3. NC/Err_Out ( Pin 55) and NC/Par_In (Pin 68) are for optional function to check address and command parity. 4. CKE1,S1 Pin is used for double side Registered DIMM.
