Memory Population Rules
When considering the memory configuration of your server, you should take into account the following:
■ For optimum performance, populate at least one DIMM per memory channel per CPU.
■ Each channel has three DIMM slots (for example, channel A = slots A1, A2, and A3).
— A channel can operate with one or two 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 mixing rules shown in Table 26
Table 26 DIMM Mixing Rules for C240 M3 Server
DIMM Parameter Mixed Mix Across a Single Bank? Mix Across Multiple Banks?
DIMM Size (4, 8, 16 GB) No—Must be same size in the
same bank
Yes—Different banks can use
different DIMM sizes (as long
as all DIMMs in a single bank
use the same DIMM size).
DIMM Speed
(1066, 1333, or 1600 MHz)
a
Notes . . .
a. Only 1333 and 1600 MHz DIMMs are currently available for the C240 M3 server.
No—Must be same speed in
the same bank.
No—All DIMMs in the server
must be same speed.
DIMM Type (R-DIMM) No—All DIMMs in a bank must
be same type.
No—All DIMMs in the server
