Cisco 16GB SD UCSC-SD-16G-C220= Manuale Utente

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 Size
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

DIMM Speed 
1333 or 1600 MHz

1

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.

DIMM Type
RDIMMs or LRDIMMs

You cannot mix LRDIMMs 

with RDIMMS

You cannot mix LRDIMMs with 

RDIMMS

DIMMs will run at 1333 MHz at either 1.35 V or 1.5 V
