Memory Slot Configuration Rules
● The 2180 supports a maximum of sixteen DDR4 ECC DIMMs. Each processor
integrates eight memory channels. RDIMMs are supported.
● The 2180 supports DIMMs of 16 GB, 32 GB, 64 GB, and 128 GB. When the
2180 is fully configured with DIMMs, the maximum memory capacity is 2048
GB.
● In the 2180, the CPU has sixteen DDR4 DIMM slots, integrating eight memory
channels. Table 6-2 describes the composition of each channel. Figure 6-1
shows the DIMM installation positions.
● DIMMs of different specifications (such as capacity, bit width, rank, and
height) cannot be mixed on one server. That is, a server must use DIMMs of
the same Part No..
