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. This section provides information on the memory population rules and
about the non-uniform memory access (NUMA) for single or dual processor system.
The memory bus may operate at speeds of 3200 MT/s, 2933 MT/s, or 2666 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
●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.
●Mixing of memory module capacities in a system is not supported.
●If memory modules with different speeds are installed, they 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 A16 are available.
○For dual-processor systems, sockets A1 to A16 and sockets B1 to B16 are available.
○In Optimizer Mode, the DRAM controllers operate independently in the 64-bit mode and provide optimized memory
performance.

Odd amount of DIMMs
per processor is allowed.
DIMMs must be populated
identically per processor.
●Populate all the sockets with white release tabs first, followed by the black release tabs.
●In a dual-processor configuration, the memory configuration for each processor must be identical. For example, if you
populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.
●Unbalanced or odd memory configuration results in a performance loss and system may not identify the memory modules
being installed, so always populate memory channels identically with equal DIMMs for best performance.
68 Installing and removing system components
●Minimum recommended configuration is to populate four equal memory modules per processor. AMD recommends limiting
processors in that system to 32 cores or less.
●Populate eight equal memory modules per processor (one DIMM per channel) at a time to maximize performance.
NOTE: Equal memory modules refer to DIMMs with identical electrical specification and capacity that may be from
different vendors.
Memory interleaving with Non-uniform memory access (NUMA)
Non-uniform memory access (NUMA) is a memory design used in multi-processing, where the memory access time depends on
the memory location relative to the processor. In NUMA, a processor can access its own local memory faster than the non-local
memory.
NUMA nodes per socket (NPS) is a new feature added that allows you to configure the memory NUMA domains per socket.
The configuration can consist of one whole domain (NPS1), two domains (NPS2), or four domains (NPS4). In the case of a
two-socket platform, an additional NPS profile is available to have whole system memory to be mapped as single NUMA domain
(NPS0). For more information on the memory interleaving for NPSx, see the Memory interleaving population rules section in this
topic.
BIOS implementation for NPSx
●The BIOS Setup menu presents the applicable NPSx options based on the underlying model number. A change to the current
NPSx is communicated to pre-BIOS firmware to take effect on the next boot. The default NPS setting is 1.
●During boot, if the selected NPSx option is not allowed for the model number (for example, if the processor model number
changes between reboot), system will halt at the end of POST with UEFI0388 message displayed. On the next reboot, the
system will fall back to NPS1 default setting.
●During boot, if the preferred interleaving for the current NPSx is not possible due to memory configuration (for example, the
memory population is inconsistent with the preferred interleaving), BIOS shows a warning message UEFI0391.
NOTE: System is functional when UEFI0391 message is displayed. However, the system may not be configured for
optimal performance.
NPS system optimization
Optimal system configuration is dependent on the processor model, memory configuration, and NPS settings. Match the
memory configuration with the NPS settings available for the processor.

Memory interleaving population rules
●NPS4: Two channel interleaving
○This interleaves channel [A and B], [C and D], etc.
○Each channel within the pair requires at least one equal memory modules populated.
○Works with three memory modules per channel pair, non-symmetrical module is stacked on top (odd configurations).
○Any memory channel where one of the two channels is not populated is not interleaved.
○There is no alternate, as all configurations can be mapped into this mode.
●NPS2: Four channel interleaving
○This interleaves the four channels on the left or right half of a processor which are channels [A, B, C, D] and [E, F, G, H].
○All four channels require equal memory modules populated.
○Each half or interleave set may have different total memory capacity with respect to each other.
●NPS1: Eight channel interleaving
○This interleaves all channels in a processor [A, B, C, D, E, F, G, H].
○All channels in a processor require equal memory modules populated.
○Single processor system creates a single NUMA node for the system.
NOTE: An exception is allowed when system has 4-channels populated [C, D, G, H] with equal memory allowing the
system to enter NPS1 mode even though all the 8 channels are not populated.
●NPS0: Sixteen channel interleaving (dual processor)
○This interleaves all 16 channels in a dual processor system.
○All channels in a system require equal memory modules populated.
○Dual processor systems create a single NUMA node for the system.

Power supply unit
NOTE: While replacing the hot swappable PSU, after next server boot; the new PSU automatically updates to the same
firmware and configuration of the replaced one. For more information about the Part replacement configuration, see the
Lifecycle Controller User's Guide at https://www.dell.com/idracmanuals
NOTE: Ensure to install the latest iDRAC 4.4x version or any later versions to support the 1100 W Titanium Mixed Mode
AC/HVDC PSU and (-48V) 1100 W DC PSU.
Hot spare feature
Your system supports the hot spare feature that significantly reduces the power overhead associated with power supply unit
(PSU) redundancy.
When the hot spare feature is enabled, one of the redundant PSUs is switched to the sleep state. The active PSU supports 100
percent of the system load, thus operating at higher efficiency. The PSU in the sleep state monitors output voltage of the active
PSU. If the output voltage of the active PSU drops, the PSU in the sleep state returns to an active output state.
If having both PSUs active is more efficient than having one PSU in the sleep state, the active PSU can also activate the
sleeping PSU.
The default PSU settings are as follows:
Installing and removing system components 131
●If the load on the active PSU is more than 50 percent of PSU rated power wattage, then the redundant PSU is switched to
the active state.
●If the load on the active PSU falls below 20 percent of PSU rated power wattage, then the redundant PSU is switched to
the sleep state.
You can configure the hot spare feature by using the iDRAC settings. For more information, see the iDRAC User’s Guide
available at www.dell.com/poweredgemanuals.

Receiving automated support with SupportAssist
Dell EMC SupportAssist is an optional Dell EMC Services offering that automates technical support for your Dell EMC server,
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
