iDRAC conguration
The Integrated Dell Remote Access Controller (iDRAC) is designed to make system administrators more productive and improve the overall
availability of Dell systems. iDRAC alerts administrators about system issues and enables them to perform remote system management.
This reduces the need for physical access to the system.
Options to set up iDRAC IP address
To enable communication between your system and iDRAC, you must rst congure the network settings based on your network
infrastructure.
NOTE
: For static IP conguration, you must request for it at the time of purchase.
This option is set to DHCP by Default. You can set up the IP address by using one of the following interfaces:

Initial system setup and conguration 19
NOTE: To access iDRAC, ensure that you connect the ethernet cable to the iDRAC9 dedicated network port or use iDRAC direct
by using the USB cable. You can also access iDRAC through the shared LOM mode, if you have opted for a system that has the
shared LOM mode enabled.
Log in to iDRAC
You can log in to iDRAC as:
• iDRAC user
• Microsoft Active Directory user
• Lightweight Directory Access Protocol (LDAP) user
If you have opted for secure default access to iDRAC, you must use the iDRAC secure default password available on the system
Information tag. If you have not opted for secure default access to iDRAC, then use the default user name and password –root and
calvin. You can also log in by using your Single Sign-On or Smart Card.
NOTE: You must have the iDRAC credentials to log in to iDRAC.
NOTE: Ensure that you change the default user name and password after setting up the iDRAC IP address.
NOTE: The Intel Quick Assist Technology (QAT) on the Dell EMC PowerEdge R740xd2 is supported with chipset integration and
is enabled through an optional license. The license les are enabled on the sleds through iDRAC.
For more information about drivers, documentation, and white papers on the Intel QAT, see https://01.org/intel-quickassist-technology.
For more information about logging in to the iDRAC and iDRAC licenses, see the latest Integrated Dell Remote Access Controller User's
Guide at Dell.com/poweredgemanuals.
You can also access iDRAC by using RACADM. For more information, see the RACADM Command Line Interface Reference Guide at

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 supported by
the processors. You can also select specic frequencies that the processors support, which can vary.
26 Pre-operating system management applications
Option Description
For best performance, you should select Maximum data rate. Any reduction in the communication link frequency
aects the performance of non-local memory accesses and cache coherency trac. In addition, it can slow access
to non-local 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.

To ensure optimal performance of your system, observe the following general guidelines when conguring your system memory. If your
system's memory congurations fail to observe these guidelines, your system might not boot, stop responding during memory
conguration, or operate with reduced memory.
The memory bus may operate at frequency can be 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the following factors:
• System prole 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 Conguration, enabling the system to be congured and run in any valid chipset architectural
conguration. The following are the recommended guidelines for installing memory modules:
• All DIMMs must be DDR4.
• x4 and x8 DRAM based memory modules can be mixed.
• Up to two RDIMMs can be populated per channel regardless of rank count.
• A maximum of two dierent ranked DIMMs can be populated in a channel regardless of rank count.
• If memory modules with dierent 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 rst, followed by the black release tabs.
• When mixing memory modules with dierent capacities, populate the sockets with memory modules with the highest capacity rst.
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 dierent 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 conguration, the memory conguration 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 congurations 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, 9, 10.
Mode-specic guidelines
The congurations allowed depend on the memory mode selected in the System BIOS.

Table 9. 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 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 conguration 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 conguration 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 oer protection against a
multi-bit uncorrectable error.
Optimizer Mode
This mode supports Single Device Data Correction (SDDC) only for memory modules that use x4 device width. It does not impose any
specic slot population requirements.
• Dual processor: Populate the slots in round robin sequence starting with processor 1.
