CPUs and DIMMs
Physical Layout
Each CPU has four DIMM channels:
■
CPU1 has channels A, B, C, and D
■
CPU2 has channels E, F, G, and H
Each DIMM channel has three banks: bank 1, 2, and 3. The blue-colored DIMM slots are for bank 1 and the
black-colored are for banks 2 and 3.
black-colored are for banks 2 and 3.
As an example, DIMM slots A1, B1, C1, and D1 belong to bank 1, while A2, B2, C2, and D2 belong to bank 2.
shows how banks and channels are physically laid out on the motherboard. The DIMM slots on the
top (channels A, B, C, and D) are associated with CPU 1, while the DIMM slots on the bottom (channels E, F,
G, and H) are associated with CPU 2. The bank 1 (blue) DIMM slots are always located farther away from a
CPU than the corresponding bank 2 or 3 (black) slots. Bank 1 slots (blue) are populated before bank 2 and 3
slots (black).
