System memory System memory guidelines The PowerEdge XE2420 system supports DDR4 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). System memory holds the instructions that are executed by the processor. Your system memory is organized into eight channels per processor (two memory sockets per channel) for a total of 16 memory sockets, where CPU 1 supports 10 DIMMs, and CPU 2 supports 6 DIMMS. In each channel, the 1st socket is marked white and the 2nd socket black. Figure 79. Memory socket location Memory channels are organized as follows: Table 37.

System memory guidelines
The PowerEdge XE2420 system supports DDR4 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). System
memory holds the instructions that are executed by the processor.
Your system memory is organized into eight channels per processor (two memory sockets per channel) for a total of 16 memory
sockets, where CPU 1 supports 10 DIMMs, and CPU 2 supports 6 DIMMS. In each channel, the 1st socket is marked white and
the 2nd socket black.
