DIMM Sockets
Figure 3-19 shows the DIMM sockets and how they are numbered on a server node board.
•
A server node has 16 DDR3 DIMM sockets (8 for each CPU).
•
Channels are labeled with letters as shown in Figure 3-19 .
For example, channel A = DIMM sockets A1, A2.
•
Each channel has two DIMM sockets. The blue socket in a channel is always socket 1.

DIMM Population Rules
Observe the following guidelines when installing or replacing DIMMs:
•
For optimal performance, spread DIMMs evenly across both CPUs and all channels.
• Populate the DIMM sockets of each CPU identically. Populate the blue DIMM 1 sockets first, then
the black DIMM 2 slots. For example, populate the DIMM slots in this order:
1.
A1, E1, B1, F1, C1, G1, D1, H1
2. A2, E2, B2, F2, C2, G2, D2, H2
•
Observe the DIMM mixing rules shown in Table 3-5 .
