System memory
The system supports DDR4 registered DIMMs (RDIMMs), load reduced DIMMs (LRDIMMs), Non-Volatile DIMMs (NVDIMMNs), and Intel Optane Data Center Persistent Memory Modules (DCPMMs). System memory holds the instructions that are
executed by the processor.
Your system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is
organized into six channels. Six memory channels are allocated to each processor. In each channel, the release tabs of the first
socket are marked white, and the second socket black.
44

General memory module installation guidelines
To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory.
If your system's memory configurations fail to observe these guidelines, your system might not boot, stop responding during
memory configuration, or operate with reduced memory.
The memory bus may operate at frequency can be 2933 MT/s, 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the
following factors:
● System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
● Maximum supported DIMM speed of the processors. For memory frequency of 2933 MT/s, one DIMM per channel is
supported.
● Maximum supported DIMM speed of the processors.
● Maximum supported speed of the DIMMs
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
The 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 installing memory modules:
● All DIMMs must be DDR4.
● RDIMMs and LRDIMMs must not be mixed.
● 64 GB LRDIMMs that are DDP (Dual Die Package) LRDIMMs must not be mixed with 128 GB LRDIMMs that are TSV
(Through Silicon Via/3DS) LRDIMMs.
● x4 and x8 DRAM based memory modules can be mixed.
● Up to two RDIMMs can be populated per channel regardless of rank count.
● Up to two LRDIMMs can be populated per channel regardless of rank count.
● A maximum of two different ranked DIMMs can be populated in a channel regardless of rank count.
● If memory modules with different speeds are installed, they will operate at the speed of the slowest installed memory
module(s).
● Populate memory module sockets only if a processor is installed.
○ For single-processor systems, sockets A1 to A12 are available.
○ For dual-processor systems, sockets A1 to A12 and sockets B1 to B12 are available.
● Populate all the sockets with white release tabs first, followed by the black release tabs.
● When mixing memory modules with different capacities, populate the sockets with memory modules with the highest
capacity first.
NOTE:
For example, if you want to mix 8 GB and 16 GB memory modules, populate 16 GB memory modules in the
sockets with white release tabs and 8 GB memory modules in the sockets with black release tabs.
● Memory modules of different capacities can be mixed provided other memory population rules are followed.
NOTE: For example, 8 GB and 16 GB memory modules can be mixed.
● In a dual-processor configuration, the memory configuration for each processor must be identical.
NOTE: For example, if you populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.
● Mixing of more than two memory module capacities in a system is not supported.
● Unbalanced memory configurations will result in a performance loss so always populate memory channels identically with
identical DIMMs for best performance.
● Populate six identical memory modules per processor (one DIMM per channel) at a time to maximize performance.
DIMM population update for Performance Optimized mode with quantity of 4 and 8 DIMMs per processor.
● When the DIMM quantity is 4 per processor, the population is slot 1, 2, 4, 5.
● When the DIMM quantity is 8 per processor, the population is slot 1, 2, 4, 5, 7, 8, 10, 11.
NVDIMM-N memory module installation guidelines
The following are the recommended guidelines for installing NVDIMM-N memory modules:
● Each system supports memory configurations with 1, 2, 4, 6, or 12 NVDIMM-Ns.
● Supported configurations have dual processors and a minimum of 12x RDIMMs.
● Maximum of 12 NVDIMM-Ns can be installed in a system.
46
Installing and removing system components
● NVDIMM-Ns or RDIMMs must not be mixed with LRDIMMs.
● DDR4 NVDIMM-Ns must be populated only on the black release tabs on processor 1 and 2.
● All slots on configurations 3, 6, 9, and 12 can be used, but a maximum of 12 NVDIMM-Ns can be installed in a system.
NOTE: NVDIMM-N memory slots are not hot-pluggable.

DCPMM installation guidelines
The following are the recommended guidelines for installing data center persistent memory module (DCPMM) memory modules:
● Each system supports maximum of one DCPMM memory module per channel.
NOTE:
If two different DCPMM capacities are mixed, an F1/F2 warning is displayed as the configuration is not
supported.
● DCPMM can be mixed with RDIMM, LRDIMM, and 3DS LRDIMM.
● Mixing of DDR4 DIMM types (RDIMM, LRDIMM, and 3DS LRDIMM), within channels, for Integrated Memory Controller
(iMC), or across sockets are not supported.
● Mixing of DCPMM operating modes (App Direct, Memory Mode) is not supported.
● If only one DIMM is populated on a channel, it should always go to the first slot in that channel (white slot).
● If a DCPMM and a DDR4 DIMM are populated on the same channel, always plug DCPMM on second slot (black slot).
● If the DCPMM is configured in Memory Mode, the recommended DDR4 to DCPMM capacity ratio is 1:4 to 1:16 per iMC.
● DCPMMs' cannot be mixed with other DCPMMs capacities or NVDIMMs.
● Mixing different capacities of RDIMMs and LRDIMMs are not allowed when DCPMM is installed.
● DCPMMs of different capacities are not allowed.
For more information about the supported DCPMM configurations, see the Dell EMC DCPMM User 's Guide at https://

Mode-specific guidelines
The configurations allowed depend on the memory mode selected in the System BIOS.
Table 8. Memory operating modes
Memory Operating Mode Description
Optimizer Mode The Optimizer Mode if enabled, the DRAM controllers
operate independently in the 64-bit mode and provide
optimized memory performance.
NOTE: DCPMM supports only Optimizer mode.
Mirror Mode The Mirror Mode if enabled, the system maintains two
identical copies of data in memory, and the total available
system memory is one half of the total installed physical
memory. Half of the installed memory is used to mirror the
active memory modules. This feature provides maximum
reliability and enables the system to continue running even
during a catastrophic memory failure by switching over to the
mirrored copy. The installation guidelines to enable Mirror
Mode require that the memory modules be identical in size,

speed, and technology, and they must be populated in sets of
6 per processor.
Single Rank Spare Mode Single Rank Spare Mode allocates one rank per channel as a
spare. If excessive correctable errors occur in a rank or
channel, while the operating system is running, they are
moved to the spare area to prevent errors from causing an
uncorrectable failure. Requires two or more ranks to be
populated in each channel.
Multi Rank Spare Mode Multi Rank Spare Mode allocates two ranks per channel as a
spare. If excessive correctable errors occur in a rank or
channel, while the operating system is running, they are
moved to the spare area to prevent errors from causing an
uncorrectable failure. Requires three or more ranks to be
populated in each channel.
With single rank memory sparing enabled, the system
memory available to the operating system is reduced by one
rank per channel.
For example, in a
dual-processor configuration with 24x 16 GB dual-rank
memory
modules, the available system memory is: 3/4 (ranks/channel)
×
24 (memory modules) × 16 GB = 288 GB, and not 24 (memory
modules) × 16 GB = 384 GB. For multi rank sparing, the
multiplier changes to 1/2 (ranks/channel).
NOTE: To use memory sparing, this feature must be
enabled in the BIOS menu of System Setup.
NOTE: Memory sparing does not offer protection against
a multi-bit uncorrectable error.
Dell Fault Resilient Mode The Dell Fault Resilient Mode if enabled, the BIOS creates
an area of memory that is fault resilient. This mode can be
used by an OS that supports the feature to load critical
applications or enables the OS kernel to maximize system
availability.
NOTE: This feature is only supported in Gold and Platinum
Intel processors.
NOTE: Memory configuration has to be of same size
DIMM, speed, and rank.
Optimizer Mode
This mode supports Single Device Data Correction (SDDC) only for memory modules that use x4 device width. It does not
impose any specific slot population requirements.
● Dual processor: Populate the slots in round robin sequence starting with processor 1.
NOTE: Processor 1 and processor 2 population should match.

storage, and networking devices. By installing and setting up a SupportAssist application in your IT environment, you can receive
the following benefits:
● Automated issue detection — SupportAssist monitors your Dell EMC devices and automatically detects hardware issues,
both proactively and predictively.
● Automated case creation — When an issue is detected, SupportAssist automatically opens a support case with Dell EMC
Technical Support.
● Automated diagnostic collection — SupportAssist automatically collects system state information from your devices and
uploads it securely to Dell EMC. This information is used by Dell EMC Technical Support to troubleshoot the issue.
● Proactive contact — A Dell EMC Technical Support agent contacts you about the support case and helps you resolve the
issue.
The available benefits vary depending on the Dell EMC Service entitlement purchased for your device. For more information
