Refer to Chapter 6 for signal description details. 2. SA and SB refer to DDR3 Channel A and DDR3 Channel B. 3. These signals are only used on processors and platforms that support ECC DIMMs. 4. These signals will not be actively used on the Intel Xeon processor 3400 series. All Control Sideband Asynchronous signals are required to be asserted/de-asserted for at least eight BCLKs for the processor to recognize the proper signal state. See Section 7.9 for the DC specifications. 68 Datasheet, Volume 1
