The following table explains the memory module installation rules for servers that have only one microprocessor (CPU1) installed. The "X" mark indicates the memory slots into which the memory modules should be installed in different situations. Note: All memory modules to be installed on a server must be the same type (LV RDIMM, RDIMM, or UDIMM) with the same rank, voltage, and frequency. Figure 34. CPU1 DIMMs Table 4.
