Memory Population Rules
When considering the memory configuration of your server, you should consider the following items:
■
Each channel has two DIMM slots (for example, channel A = slots A1 and A2).
— 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 blue slots in the channels first: A1, E1, B1, F1, C1, G1, D1, H1
— Fill black slots in the channels second: A2, E2, B2, F2, C2, G2, D2, H2
■
Any DIMM installed in a DIMM socket for which the CPU is absent is not recognized.
■
Observe the DIMM mixing rules shown in

DIMM Parameter
Mix Across a Single Bank?
Mix Across Multiple Bank?
DIMM Size
RDIMM = 4, 8, or 16 GB
RDIMM = 4, 8, or 16 GB
LRDIMM = 32 GB
No—Must be same size in
the same bank.
You cannot mix 32 GB
LRDIMMs with any RDIMM
Yes—Different banks can use
different DIMM sizes (as long
as all DIMMs in a single bank
use the same DIMM size).
You cannot mix 32 GB
LRDIMMs with any RDIMM

Notes . . .
1. Only 1333- and 1600-MHz DIMMs are currently available for the C220 M3 server.
No—Must be same speed in
the same bank.
Yes—but if DIMMs of mixed
speed are used, the server
will clock down to the lowest
speed.
