SUPPLEMENTAL MATERIAL

CPUs and DIMMs

Physical Layout

Each CPU has three DIMM channels:

■ CPU1 has channels A, B, and C

■ CPU2 has channels D, E, and F

Each DIMM channel has two banks: Bank 1 and Bank 2. The blue-colored DIMM banks are for Bank 1 and the

black-colored are for Bank 2.

As an example, DIMM slots A1, B1, and C1 belong to Bank 1, while A2, B2, and C2 belong to Bank 2.

Figure 7 shows how banks and channels are physically laid out on the motherboard. The DIMM slots on the

top (channels A, B, and C) are associated with CPU 1, while the DIMM slots on the bottom (channels D, E,

and F) are associated with CPU 2. Bank 1 slots (blue) are populated before Bank 2 slots (black).
