Green A valid power source is connected to the PSU and the PSU is operational.
Blinking amber Indicates a problem with the PSU.
Not illuminated Power is not connected to the PSU.
Blinking green When the firmware of the PSU is being updated, the PSU handle blinks green.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating
firmware. If firmware update is interrupted, the PSUs do not function.
Blinking green and turns
off
When hot-plugging a PSU, the PSU handle blinks green five times at a rate of 4 Hz and turns off.
This indicates a PSU mismatch with respect to efficiency, feature set, health status, or supported
voltage.
CAUTION: If two PSUs are installed, both the PSUs must have the same type of label;
for example, Extended Power Performance (EPP) label. Mixing PSUs from previous
generations of PowerEdge servers is not supported, even if the PSUs have the same
power rating. This results in a PSU mismatch condition or failure to turn the system
on.
CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking
indicator. Swapping the PSU to make a matched pair can result in an error condition
and unexpected system shutdown. To change from a high output configuration to a
low output configuration or vice versa, you must turn off the system.
CAUTION: AC PSUs support both 240 V and 120 V input voltages with the exception of
Titanium PSUs, which support only 240 V. When two identical PSUs receive different
input voltages, they can output different wattages, and trigger a mismatch.
CAUTION: If two PSUs are used, they must be of the same type and have the same
maximum output power.
CAUTION: Combining AC and DC PSUs is not supported and triggers a mismatch.

Processor Settings details
About this task
The Processor Settings screen details are explained as follows:
Option Description
Logical
Processor
Enables or disables the logical processors and displays the number of logical processors. If this option is
set to Enabled, the BIOS displays all the logical processors. If this option is set to Disabled, the BIOS
displays only one logical processor per core. This option is set to Enabled by default.
CPU
Interconnect
Speed
Enables you to govern the frequency of the communication links among the processors in the system.
NOTE: The standard and basic bin processors support lower link frequencies.
The options available are Maximum data rate, 10.4 GT/s, and 9.6 GT/s. This option is set to Maximum
data rate by default.
Maximum data rate indicates that the BIOS runs the communication links at the maximum frequency that
is supported by the processors. You can also select specific frequencies that the processors support,
which can vary.
For best performance, you should select Maximum data rate. Any reduction in the communication link
frequency affects the performance of non-local memory accesses and cache coherency traffic. Besides,
it can slow access to non-local I/O devices from a particular processor.
However, if power-saving considerations outweigh performance, you might want to reduce the frequency
of the processor communication links. If you do this, you should localize memory and I/O accesses to the
nearest NUMA node to minimize the impact to system performance.
Virtualization
Technology
Enables or disables the virtualization technology for the processor. This option is set to Enabled by
default.
Adjacent Cache
Line Prefetch
Optimizes the system for applications that need high utilization of sequential memory access. This option

Cluster
Sub NUMA Clustering (SNC) is a feature for breaking up the LLC into disjoint clusters based on address
range, with each cluster bound to a subset of the memory controllers in the system. It improves average
latency to the LLC. Enables or disables the Sub NUMA Cluster. This option is set to Disabled by default.
UPI Prefetch Enables you to get the memory that is read started early on DDR bus. The Ultra Path Interconnect (UPI)
Rx path will spawn the speculative memory that is read to Integrated Memory Controller (iMC) directly.
This option is set to Enabled by default.
LLC Prefetch Enables or disables the LLC Prefetch on all threads. This option is set to Disabled by default.
Dead Line LLC
Alloc
Enables or disables the Dead Line LLC Alloc. This option is set to Enabled by default. You can enable this
option to enter the dead lines in LLC or disable the option to not enter the dead lines in LLC.
Directory AtoS Enables or disables the Directory AtoS. AtoS optimization reduces remote read latencies for repeat read
accesses without intervening writes. This option is set to Disabled by default.
Logical
Processor Idling
Enables you to improve the energy efficiency of a system. It uses the operating system core parking
algorithm and parks some of the logical processors in the system which in turn allows the corresponding
processor cores to transition into a lower power idle state. This option can only be enabled if the
operating system supports it. It is set to Disabled by default.
Pre-operating system management applications 49
Option Description
Configurable TDP Enables you to configure the TDP level. The available options are Nominal, Level 1, and Level 2. This
option is set to Nominal by default.
NOTE: This option is only available on certain stock keeping units (SKUs) of the processors.

System memory
System memory guidelines
The PowerEdge systems support DDR4 Registered DIMMs (RDIMMs), and Load Reduced DIMMs (LRDIMMs). The processor
runs the instructions that are held by the system memory.
Your system contains 16 memory sockets. Processor 1 supports up to 10 memory sockets and Processor 2 supports up to six
memory sockets. Six memory channels are allocated to each processor. Processor 1 has four 2xDIMM slots per channel and two
1xDIMM slot per channel. Processor 2 has six 1xDIMM per channel.
100 Installing and removing system components
Figure 55. Memory socket locations
Memory channels are organized as follows:
Table 44. Memory channels
Processor Channel 0 Channel 1 Channel 2 Channel 3 Channel 4 Channel 5
Processor 1 Slots A1 and A7 Slots A2 and
A8
Slots A3 Slots A4 and A9 Slots A5 and A10 Slots A6
Processor 2 Slots B1 Slots B2 Slots B3 Slots B4 Slots B5 Slots B6
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.
●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 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.
Installing and removing system components 101
●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 A10 are available.
○For dual-processor systems, sockets A1 to A10 and sockets B1 to B6 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, 9, 10.
Mode-specific guidelines
The configurations allowed depend on the memory mode selected in the System BIOS.
Table 45. 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.
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
102 Installing and removing system components
Table 45. Memory operating modes (continued)
Memory Operating Mode Description
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 sixteen 16
GB dual-rank memory modules, the available system memory:
16 GB x 16(memory modules) - 8GB(1 rank sparing/channel) x
12(channel) = 256 GB - 96 GB = 160 GB. For multi rank
sparing, in a dual-processor configuration with sixteen 64 GB
quad-rank memory modules, the available system memory:
64 GB x 16(memory modules) - 32 GB(2 rank sparing/
channel)
x 12 (channel) = 1024 GB - 384 GB = 640 GB.
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.

Power supply units
NOTE: For more information, see the Technical specifications section.
CAUTION: If two PSUs are installed, both the PSUs must have the same type of label. For example, Extended
Power Performance (EPP) label. Mixing PSUs from previous generations of PowerEdge servers is not
supported, even if the PSUs have the same power rating. Mixing PSUs will result in mismatch condition or
failure to turn the system on.
NOTE: When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – without
redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both PSUs
when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs is put into the sleep mode when system utilization
is low in order to maximize efficiency.
NOTE: If two PSUs are used, they must be of the same maximum output power.
152 Installing and removing system components
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 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:
●If the load on the active PSU is more than 50 percent, then the redundant PSU is switched to the active state.
●If the load on the active PSU falls below 20 percent, 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 about iDRAC settings, see the
Integrated Dell Remote Access Controller User’s Guide available at https://www.dell.com/idracmanuals.
