Figure 56. Cable routing - System with 2 x 3.5-inch rear drive backplane connected to cable chain assembly System memory System memory guidelines The XC systems support DDR4 Registered DIMMs (RDIMMs). System memory holds the instructions that are executed by the processor. Your system contains 16 memory sockets. Processor 1 supports up to 10 memory sockets and Processor 2 supports up to 6 memory sockets. Six memory channels are allocated to each processor.

• • • • • • • • If memory modules with different speeds are installed, they will operate at the speed of the slowest installed memory module(s) or slower depending on the system DIMM configuration. Populate memory module sockets only if a processor is installed. For single-processor systems, sockets A1 to A10 are available. For dual-processor systems, sockets A1 to A10 and sockets B1 to B6 are available. Populate all the sockets with white release tabs first, followed by the black release tabs.
Memory Operating Mode Description NOTE: Memory sparing does not offer protection against a multi-bit uncorrectable error. Optimizer Mode This mode supports Single Device Data Correction (SDDC) only for memory modules that use x4 device width. It does not impose any specific slot population requirements. • Dual processor: Populate the slots in round robin sequence starting with processor 1. NOTE: Processor 1 and processor 2 population should match. Table 8.
