Next steps
1 Connect all the cables to the rear drive backplane.
2 Install all the drives.
3 Follow the procedure listed in After working inside your system.
System memory
The system supports DDR4 registered DIMM (RDIMMs) slots and load reduced DIMM (LRDIMMs) slots. System memory holds the
instruc
tions that are executed by the processor.
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 2666 MT/s, 2400 MT/s, 2133 MT/s, or 1866 MT/s depending on the following factors:
• DIMM type (RDIMM or LRDIMM)
• Number of DIMM slots populated per channel
• System prole selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
• Maximum supported DIMM frequency of the processors
NOTE: For maximum DDR frequency of the processor, refer to AMD EPYC 7000 series table below.
