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 CPUs 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 nonlocal memory accesses and cache coherency traffic. In addition, it can slow access
to nonlocal I/O devices from a particular CPU.
However, if power-saving considerations outweigh performance, you might want to reduce the frequency of the
CPU 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.

In-Band
Manageability
Interface
When set to Disabled, this setting will hide the Management Engine's (ME), HECI devices, and the system's IPMI
devices from the operating system. This prevents the operating system from changing the ME power capping
settings, and blocks access to all in-band management tools. All management should be managed through out-of-
band. This option is set to Enabled by default.
NOTE: BIOS update requires HECI devices to be operational and DUP updates require IPMI
interface to be operational. This setting needs to be set to Enabled to avoid updating errors.
Secure Boot Enables Secure Boot, where the BIOS authenticates each pre-boot image by using the certificates in the Secure
Boot Policy. Secure Boot is set to Disabled by default.
Secure Boot
Policy
When Secure Boot policy is set to Standard, the BIOS uses the system manufacturer’s key and certificates to
authenticate pre-boot images. When Secure Boot policy is set to Custom, the BIOS uses the user-defined key
and certificates. Secure Boot policy is set to Standard by default.
Secure Boot Mode Configures how the BIOS uses the Secure Boot Policy Objects (PK, KEK, db, dbx).
If the current mode is set to Deployed Mode, the available options are User Mode and Deployed Mode. If the
current mode is set to User Mode, the available options are User Mode, Audit Mode, and Deployed Mode.
Options Description
User Mode In User Mode, PK must be installed, and BIOS performs signature verification on
programmatic attempts to update policy objects.
The BIOS allows unauthenticated programmatic transitions between modes.
Deployed Mode Deployed Mode is the most secure mode. In Deployed Mode, PK must be installed and
the BIOS performs signature verification on programmatic attempts to update policy
objects.
Deployed Mode restricts the programmatic mode transitions.
Audit Mode In Audit mode, PK is not present. The BIOS does not authenticate programmatic updates
to the policy objects, and transitions between modes.
Audit Mode is useful for programmatically determining a working set of policy objects.
BIOS performs signature verification on pre-boot images and logs results in the image
Execution Information Table, but executes the images whether they pass or fail
verification.
Secure Boot
Policy Summary
Specifies the list of certificates and hashes that secure boot uses to authenticate images.
Secure Boot
Custom Policy
Settings
Configures the Secure Boot Custom Policy. To enable this option, set the Secure Boot Policy to Custom option.

System memory
The system supports DDR4 registered DIMMs (RDIMMs), load reduced DIMMs (LRDIMMs), Non-Volatile DIMMs (NVDIMM-Ns), 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.

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 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.
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.
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.
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.
• To ensure proper system cooling, memory module blanks must be installed in memory sockets that are not occupied.
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.
• 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.
For more information on the supported NVDIMM-N configurations, see the NVDIMM-N User Guide at www.dell.com/poweredgemanuals.

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 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://www.dell.com/

Mode-specific guidelines
The configurations allowed depend on the memory mode selected in the System BIOS.
Table 12. 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).
Installing and removing system components 71
Memory Operating Mode Description
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.

Trusted Platform Module
Trusted Platform Module (TPM) is a dedicated microprocessor designed to secure hardware by integrating cryptographic keys into
devices. Software can use a TPM to authenticate hardware devices. Because each TPM chip has a unique and secret RSA key which is
embedded during the manufacture of the TPM, it is capable of performing platform authentication operation.
Upgrading the TPM
Prerequisites
1. Follow the safety guidelines listed in Safety instructions.
2. Follow the procedure listed in Before working inside your sled.
3. Disconnect the cables.
4. Remove the drive backplane.

NOTE:
• Ensure that your operating system supports the version of the TPM module being installed.
• Ensure that you download and install the latest BIOS firmware on your system.
• Ensure that the BIOS is configured to enable UEFI boot mode.
About this task
CAUTION: If you are using the Trusted Platform Module (TPM) with an encryption key, you may be prompted to create
a recovery key during program or System Setup. Work with the customer to create and safely store this recovery key.
When replacing this system board, you must supply the recovery key when you restart your system or program before
you can access the encrypted data on your hard drives.
CAUTION: After the TPM plug-in module is installed, it is cryptographically bound to that specific system board. Any
attempt to remove an installed TPM plug-in module breaks the cryptographic binding, the removed TPM cannot be
reinstalled or installed on another system board.

Thermal
PowerEdge servers have an extensive collection of sensors that automatically track thermal activity, which helps regulate temperature
thereby reducing server noise and power consumption. The sensors in the MX740c interact with the chassis management services
module which regulates fan speed. All fans which cool the MX740c are contained in the MX7000 chassis.
Thermal management of PowerEdge MX740c delivers high performance for the right amount of cooling to components at the lowest fan
speeds across a wide range of ambient temperatures from 10°C to 35°C (50°F to 95°F) and to extended ambient temperature ranges
(see Environmental Specifications section). The benefits to you are lower fan power consumption (lower server system power and data
center power consumption) and greater acoustical versatility.
For detailed information about thermal please consult the MX7000 Technical Guide.
