Cisco Cisco UCS B260 M4 Blade Server Ficha De Dados

— Slot 2 - E2, F2, G2, and H2 (black DIMM slots)

— Slot 3 - E3, F3, G3, and H3 (white DIMM slots)

The DIMM and CPU physical layout is shown in 

. The 12 DIMM slots at the left are 

controlled by CPU 1 and the 12 DIMM slots on the right are controlled by CPU 2.

When considering the memory configuration, 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 as follows.

— Fill blue slots in the channels first

— Fill black slots in the channels second

— Fill white slots in the channels third

■

Any DIMM installed in a DIMM socket for which the CPU is absent is not recognized.

■

Observe the DIMM mixing rules shown in 

1. Although different DIMM capacities can exist in the same slot, this will result in less than optimal performance. 

For optimal performance, all DIMMs in the same slot should be identical.

DIMM Capacity
RDIMM = 8

2

, 16, or 32 GB

LRDIMM = 32 or 64 GB
TSV-RDIMM = 64 GB

2. On the B200 M4, only 8 GB 2133-MHz (not 2400-MHz) DIMMs are supported and only with v3 CPUs.

DIMMs in the same channel (for 

example, A1, A2, and A3) can have 

different capacities.
 

Do not mix TSV-RDIMMS with 

LRDIMMs nor RDIMMs

For best performance, DIMMs in the 

same slot (for example, A1, B1, C1, 

D1) should have the same capacity.
 

Do not mix TSV-RDIMMS with LRDIMMs 

nor RDIMMs
