Troubleshooting the server memory
Memory DIMM load order
For a minimally loaded server, two equal-size DIMMs must be installed in the DIMM slots. For more
information, see Table 6 (page 47).
Memory subsystem behaviors
The processor and the integrated memory controller provides increased reliability of DIMMs. The
memory controller built into the 9300 series processor doubles memory rank error correction from
4 bytes to 8 bytes of a 128 byte cache line, during cache line misses initiated by processor cache
controllers and by DMA operations initiated by I/O devices. This feature is called double DRAM
sparing, since 2 of 72 DRAMs in any DIMM pair can fail without any loss of server performance.
Corrective action, such as DIMM/memory expander replacement, is required when a threshold is
reached for multiple double-byte errors from one or more DIMMs in the same rank. And when any
uncorrectable memory error (more than 2 bytes) or when no pair of like DIMMs is loaded in rank
