DCPMM Installation order: Memory mode with two processors
When implementing Memory mode, any supported DIMMs in any capacity can be installed.
When two processors are installed in the server:
• Processors 1 and 2 are installed in the lower system board of the lower compute tray.
Several configurations are supported with implementing Memory mode with two 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
