General Memory Module Installation Guidelines
Your system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset
architectural configuration. The following are the recommended guidelines for best performance:
• RDIMMs and LRDIMMs must not be mixed.
• x4 and x8 DRAM based DIMMs can be mixed. For more information, see Mode-Specific Guidelines.
• Populate only one quad-rank RDIMM per channel. The quad-rank RDIMM must be populated in the first slot with
white release levers, while the second and third slots remain empty.
• Populate up to three dual- or single-rank RDIMMs per channel.
• Up to three quad rank LRDIMMs can be populated per channel.
• Up to three LRDIMMs can be populated regardless of rank count.
• Populate DIMM sockets only if a processor is installed. For dual-processor systems, sockets A1 to A12, B1 to B12
and sockets C1 to C12, D1 to D12 are available. Each processor requires a minimum of 2 DIMMs, which must be
identical.
• Populate all sockets with white release lever first, then black, and then green.
• Populate the sockets by highest rank count in the following order — first in sockets with white release levers, then
black, and then green. For example, if you want to mix quad-rank and dual-rank LRDIMMs, populate quad-rank
LRDIMMs in the sockets with white release tabs and dual-rank LRDIMMs in the sockets with black release tabs.
• The memory configuration for each processor should be identical. For example, if you populate socket A1 and B1 for
processor 1, then populate socket C1 and D1 for processor 2, and so on.
• Memory modules of different sizes can be mixed provided that other memory population rules are followed (for
example, 4 GB and 8 GB, and 16 GB memory modules can be mixed).
• Populate four DIMMs per processor (one DIMM per channel) at a time to maximize performance.
• If memory modules with different speeds are installed, they will operate at the speed of the slowest installed
memory module(s) or slower depending on system DIMM configuration.
모드별 지침
4개의 메모리 채널이 각 프로세서에 할당됩니다. 허용되는 구성은 선택한 메모리 모드에 따라 다릅니다.
노트: x4 및 x8 DRAM 기반 DIMM은 혼합되어 RAS 기능에 대한 지원을 제공할 수 있습니다. 그러나 특정 RAS
기능에 대한 모든 지침이 준수되어야 합니다. x4 DRAM 기반 DIMM은 메모리 최적화(독립 채널) 모드에서
SDDC(Single Device Data Correction)를 유지합니다. x8 DRAM 기반 DIMM의 경우 SDDC가 지원되도록 하려면
고급 ECC 모드가 필요합니다.
다음 항목에서는 각 모드별로 추가적인 슬롯 채우기 지침을 제공합니다.
