Memory
The PowerEdge MX740c supports up to 24 DIMMs, with up to 3TB of memory and speeds up to 2666MT/s. The MX740c supports
registered (RDIMMs) and load reduced DIMMs (LRDIMMs) which use a buer to reduce memory loading and provide greater
density, allowing for the maximum platform memory capacity. Unbuered DIMMs (UDIMMs) are not supported.
Supported memory
The table below lists the memory technologies supported by the PowerEdge MX740c.

NVDIMM 2666 16 1 x4 1.2V
Memory speed
The MX740c supports memory speeds of 2666 MT/s and 2400 MT/s depending on the processor installed. All memory operates at
the same voltage. By default, the speed will be the highest common supported speed between the CPUs and DIMMs. The operating
speed of the memory is also determined by the maximum speed supported by the processor, the speed settings, and the operating
voltage of the system that are in the BIOS.
The table below lists the memory conguration and performance details for MX740c, based on the quantity and type of DIMMs per
memory channel.

Memory congurations
The MX740c servers support exible memory congurations ranging from capacities of 8GB (minimum) to 3TB (maximum). The
MX740c supports up to 12 DIMMs per processor (up to 24 DIMMs in a dual- processor conguration). Each server has 6 memory
channels per processor, with each channel supporting up to 2 DIMMs.
System supports a exible memory conguration, according to the following population rules:
• Speed: If DIMMs of dierent speeds are mixed, all channels across all processors operate at the slowest DIMM's common
frequency
• DIMM type: Only one type of DIMM is allowed per system: RDIMM, or LRDIMM. These types cannot be mixed.
• DIMMs with dierent data widths can be mixed. For 14G, DIMMs with x4 and x8 data widths are supported and mixing is
allowed.
• Can mix DIMMs with dierent capacities.
– Population rules require the largest capacity DIMM be placed rst (slot A1 populated rst, then A2, and so on. The second
CPU mirrors the rst CPU population).
– Maximum of two dierent capacity DIMMs allowed in a system.
• Mixing of DIMMs with dierent ranks are allowed.
– Maximum of two dierent rank DIMMs allowed in a system.
Memory RAS features
Reliability, Availability, and Serviceability (RAS) features help keep the system online and operational without signicant impact to
performance, and can decrease data loss and crashing due to errors. RAS aids in rapid, accurate diagnosis of faults which require
service.
The table below describes the memory RAS features supported on the MX740C.
Feature Description
Dense conguration optimized prole Increased memory reliability can be a result from this selectable
platform prole that adjusts parameters to reduce faults
regarding refresh rates, speed, temperature, and voltage.
Memory demand and patrol scrubbing Demand scrubbing is the ability to write corrected data back to
the memory once a correctable error is detected on a read
transaction. Patrol scrubbing proactively searches the system
memory, repairing correctable errors.
Recovery from single DRAM device failure (SDDC) Recovery from Single DRAM Device Failure (SDDC) provides
error checking and correction that protects against any single
memory chip failure as well as multi- bit errors from any portion
of a single memory chip.
Failed DIMM isolation This feature provides the ability to identify a specic failing
DIMM channel pair, thereby enabling the user to replace only the
failed DIMM pair.
Memory mirroring Memory mirroring is a method of keeping a duplicate (secondary
or mirrored) copy of the contents of memory as a redundant
backup for use if the primary intra-socket memory fails. The
mirrored copy of the memory is stored in memory of the same
processor socket.
17

Feature Description
Memory address parity protection This feature provides the ability to detect transient errors on the
address lines of the DDR channel.
Memory sparing (rank) Memory sparing allocates one rank per channel as a spare. If
excessive correctable errors occur in a rank or channel, they are
moved to the spare area while the operating system is running to
prevent the errors from causing an uncorrectable failure.
Memory thermal throttling This feature helps to optimize power or performance and can
also be used to prevent DIMMs from overheating.

Storage
With a variety of storage controllers and drive types, the PowerEdge MX740c provides expandability that allows you to tailor your
storage to match your workload and operational demands. Options include boot devices, a portfolio of PERC controllers and HBAs,
SAS and SATA hard drives and SSDs, and NVMe SSDs.
Supported hard drives
The MX740c supports up to six 2.5-inch, hot-swappable SAS, SATA hard drives, SSDs, or PCIe NVMe drives. The drives are supplied
in a hot-swappable drive carrier and connect to the system board or RAID controller through the backplane.
NOTE: When NVDIMMs are installed in the MX740c, the available 2.5-inch drive bays are reduced to 4 to accommodate
the battery needed to protect the DIMMs during a power loss.
RAID controllers
PERC provides a base RAID HW controller without consuming a PCIe slot by using a small form factor and high density connector to
the system board.
The following table shows the PERC series oerings.

Internal Dual SD module (IDSDM)
The PowerEdge MX740c supports an optional Internal Dual SD module (IDSDM). The IDSDM module supports two microSD cards
which are available in capacities of 16GB, 32GB, and 64GB. There are two dip switches on the IDSDM module for write-protection.
One IDSDM card slot is dedicated for redundancy.
19

The IDSDM shares the same location as the BOSS-S1 module and connects using a Dell EMC-proprietary PCIe x1 slot that uses a
USB interface to the host.
NOTE: The PowerEdge MX740c supports either the optional IDSDM or the BOSS S-1 module but cannot support both
simultaneously.
The intended use of IDSDM is to support hypervisor boot: a minimal OS that primarily resides in memory and does not depend on the
IDSDM heavily for I/O. Writes should be minimized as the SD media can wear out.
The IDSDM card provides the following features:
• Full RAID-1 functionality
• Enables support for Secure Digital eXtended Capacity (SDXC) cards
• USB interface to the host system
• I2C interface to the host system and onboard EEPROM for out-of-band status reporting
• Dual card operation - maintains a mirrored conguration by using SD cards in both the slots and provides redundancy
• In addition to the redundancy setting, a separate BIOS setup option exists for IDSDM port enable or disable
It is recommended that customers use Dell EMC branded microSD cards associated with the IDSDM congured systems.
vFlash
vFlash is a dedicated microSD card on the iDRAC module and is connected to and controlled by iDRAC. It emulates USB ash
storage to the operating system (OS), but its contents can be updated remotely through the iDRAC network. Some applications of
vFlash include:
• Backup and restore the platform in case you need to replace the motherboard.
• Download a custom image and instruct the BIOS to boot to it.
• Store data for the local OS user.
vFlash microSD cards are available in 16GB capacities. It is recommended that customers use Dell EMC branded microSD cards
associated with the iDRAC module.
Boot Optimized Storage Solution (BOSS)
BOSS is a simple RAID solution card designed specically for booting the system's operating system, which supports up to two 6
Gbps M.2 SATA drives. This card has a x8 connector using PCIe gen 2.0 x2 lanes, available only in the low-prole and half-height
form factor.
The following table shows the specications for the BOSS module:
