Cpu Configuration With Memory Mirroring - Cisco UCS C480 M5 Manual

Normal CPU/Memory Configuration (no memory mirroring)
There are two CPU modules, one in each CPU bay. The lower CPU module occupies Bay 1 and the upper CPU
module occupies Bay 2. CPU 1 and CPU2 are in Bay 1; CPU 3 and 4 are in Bay 2.
Select from 4, 6, 8, or 12 DIMMs per CPU (DIMMs for all four CPUs must be configured identically). The
DIMMs will be placed by the factory as shown in the following tables.
4 (A1, B1); (D1, E1)
6 (A1, B1, C1); (D1, E1, F1)
8 (A1, A2, B1, B2); (D1, D2, E1, E2)
12 (A1, A2, B1, B2, C1, C2); (D1, D2, E1, E2, F1, F2)
4 (G1, H1); (K1, L1)
6 (G1, H1, J1); (K1, L1, M1)
8 (G1, G2, H1, H2); (K1, K2, L1, L2)
12 (G1, G2, H1, H2, J1, J2); (K1, K2, L1, L2, M1, M2)
4 (A1, B1); (D1, E1)
6 (A1, B1, C1); (D1, E1, F1)
8 (A1, A2, B1, B2); (D1, D2, E1, E2)
12 (A1, A2, B1, B2, C1, C2); (D1, D2, E1, E2, F1, F2)
4 (G1, H1); (K1, L1)
6 (G1, H1, J1); (K1, L1, M1)
8 (G1, G2, H1, H2); (K1, K2, L1, L2)
12 (G1, G2, H1, H2, J1, J2); (K1, K2, L1, L2, M1, M2)
