Hardware Setup When installing DIMMs, you must follow the following population rules to deliver the best performance: ƒ Maximize number of channels populated first ƒ Balanced DIMM population across channels and sockets. Table 10. Memory Population Table 1 DIMM 2 DIMMs 3 DIMMs 4 DIMMs 6 DIMMs DIMM_A2 - ; ; DIMM_A1 ; ; ; ; CPU 1 Configuration DIMM_B2 DIMM_B1 - - - ; - ; - ; ; ; ; DIMM_C2 - ; DIMM_C1 - ; ; ; 1 DIMM 2 DIMMs 3 DIMMs 4 DIMMs 6 DIMMs DIMM_D2 - ; ; DIMM_D1 ; ; ; ; CPU 2 Configuration DIMM_E2 DIMM_E1 - - - ; - ; - ; ; ; ; DIMM_F2 - ; DIMM_F1 - ; ; ; With two processors installed, the system will operate only if the DIMM slots of one processor are populated. In this case, memory is shared between the two processors. However, due to the associated latency of this configuration, this is NOT a recommended operating mode. You can find additional technical information for the memory sub-system in the Technical Product Specification (TPS). 2.3.3 Installing a DIMM CAUTION Before adding or removing DIMMs or other system components, you must unplug the power supply. Failure to do so may cause severe damage to both the server board and the components. 1. Unlock a DIMM socket by pressing the retaining clips outward. 2. Align a DIMM on the socket so the notch on the DIMM matches the break on the socket. 18 Intel® Server System SR1670HV Service Guide
