DCPMM Installation order: Memory mode with six processors

When implementing Memory mode, any supported DIMMs in any capacity can be installed. However, you should consider using DIMMs that are greater than 32 GB.

When six processors are installed in the server:
  • Processors 1 and 2 are installed in the lower system board of the lower compute tray.

  • Processors 3 and 4 are installed in the upper system board of the lower compute tray.

  • Processors 5 and 6 are installed in the lower system board of the upper compute tray.

Several configurations are supported with implementing Memory mode with six processors:
  • 6 DCPMMs/6 DRAM DIMMs per processor

  • 4 DCPMMs/6 DRAM DIMMs per processor

  • 2 DCPMMs/6 DRAM DIMMs per processor

  • 2 DCPMMs/4 DRAM DIMMs per processor

6 DCPMMs/ 6 DRAM DIMMs per processor
