Memory Population Rules
When considering the memory configuration of your server, you should take into account the following:
■ Each channel has three DIMM slots (for example, channel A = slots A1, A2, and A3).
— A channel can operate with one, two, or three DIMMs installed.
— If a channel has only one DIMM, populate slot 1 first (the blue slot).
■ When both CPUs are installed, populate the DIMM slots of each CPU identically.
— Fill bank 1 blue slots in the channels first: A1, E1, B1, F1, C1, G1, D1, H1
— Fill bank 2 black slots in the channels second: A2, E2, B2, F2, C2, G2, D2, H2
— Fill bank 3 black slots in the channels third: A3, E3, B3, F3, C3, G3, D3, H3
■ Any DIMM installed in a DIMM socket for which the CPU is absent is not recognized.
■ Observe the DIMM rules shown in Tab le 35
Table 35 DIMM Rules for C240 M3 Servers

DIMM in the Same Bank

Notes . . .
1. Although you can have different DIMM capacities in the same bank, this will result in less than optimal
performance. For optimal performance, all DIMMs in the same bank should be identical.
DIMM Capacity
RDIMM = 4, 8, or 16 GB
LRDIMM = 32 GB
UDIMM = 4 GB
DIMMs in the same channel (for
example, A1, A2, A3) can have
different capacities.
You cannot mix 32 GB LRDIMMs with any
RDIMM or UDIMM
You cannot mix 4 GB UDIMMs with any
RDIMM or LRIMM
For best performance, DIMMs in the
same bank (for example, A1, B1, C1,
D1) should have the same capacity.
You cannot mix 32 GB LRDIMMs with
any RDIMM or UDIMM
You cannot mix 4 GB UDIMMs with
any RDIMM or LRIMM
DIMM Speed
1866-, 1600-, or 1333-MHz

2. Only 1866-, 1600-, and 1333-MHz DIMMs are currently available for the C240 M3 server.
DIMMs will run at the lowest speed of
the DIMMs/CPUs installed
