DCPMM Installation order: Mixed Memory mode with four processors

When implementing Mixed Memory mode, any supported DIMMs in any capacity can be installed.

When four 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.

Several configurations are supported with implementing Mixed 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​
