CONFIGURING the SERVER
13
(3) 1-CPU Configuration with Memory Mirroring
■ 16 DIMMs capacity total
■ Select 2, 4, or 8 DIMM kits (4, 8, or 16 DIMMs) for CPU1. The DIMMs will be placed by the
factory as shown in the following table:
■ Choose the memory mirroring option (N01-MMIRROR) as shown in Table 4 on page 11.
CPU2
2 (D0, D1) - blue slots
4 (D0, D1) – (D4, D5) - blue slots
8 (D0, D1) – (D4, D5) - blue slots; (D2, D3) – (D6, D7) - black slots
16 (D0, D1) – (D4, D5) - blue slots; (D2, D3) – (D6, D7) - black slots
(E0, E1) – (E4, E5) - blue slots; (E2, E3) – (E6, E7) - black slots
24 (D0, D1) – (D4, D5) - blue slots; (D2, D3) – (D6, D7) - black slots

DIMM Placement in Numbered/Colored DIMM Slots
(Channel C not used with memory mirroring)
4 (A0, A1) mirrored to (B0, B1)
8 (A0, A1, A2, A3) mirrored to (B0, B1, B2, B3)
16 (A0, A1, A2, A3, A4, A5, A6, A7) mirrored to (B0, B1, B2, B3, B4, B5, B6, B7)
NOTE: System performance is optimized when the DIMM memory type and the DIMM
quantity is equal for both CPUs.
