Processors
The PowerEdge T440 server features the exceptional performance, value, and power eciency of the Intel Xeon Scalable Processor.
These processors provide high performance no matter what your constraint—oor space, power, or budget—and on workloads that
range from the most complicated scientic exploration to crucial web-serving and infrastructure applications. In addition to providing
raw performance gains, improved I/O is also made possible with Intel Integrated I/O, which can reduce latency by adding more lanes
and doubling bandwidth. This helps to reduce network and storage bottlenecks, which improves the processor performance
capabilities.
Processor features
The Intel Xeon Processor Scalable Family provides the foundation for a powerful datacenter platform. The key features are as
follows:
• Higher Per-Core Performance: Up to 28 cores, delivery high performance and scalability for compute-intensive workloads across
compute, storage & network usages
• Greater Memory Bandwidth/Capacity: 50% increased memory bandwidth and capacity. 6 memory channels vs. 4 memory
channels of previous generation for memory intensive workloads
• Expanded I/O: 48 lanes of PCIe 3.0 bandwidth and throughput for demanding I/O-intensive workloads
• Intel Ultra Path Interconnect (UPI): Up to three Intel UPI channels increase scalability of the platform to as many as eight
sockets, as well as improves inter-CPU bandwidth for I/O intensive workloads
• Intel Advanced Vector Extensions 512 (AVX-5120): With double the ops per clock cycle compared to previous generation Intel
AVX2. Intel AVX-512 boosts performance and throughput for the most demanding computational tasks in applications
• Security without Compromise: Near-zero encryption overhead enables higher performance on all secure data transactions

Memory
The PowerEdge T440 supports up to 768 GB of memory with 16 DIMMs, and at speeds up to 2666 MT/s, providing high
performance in various applications. High memory density ensures that there is no compromise in virtualization.
The PowerEdge T440 supports both registered DIMMs (RDIMM) 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.
The system supports:
• Up to six channels with two DPC and total 16 DIMMs
• DDR4 RDIMM/LRDIMM
• Only registered ECC DDR4 DIMMs
• DDR4 speeds up to 2666 MT/s

Memory population guidelines
Both systems support a exible memory conguration, according to the following population guidelines:
• Speed: If DIMMs of dierent speeds are mixed, all channels across all processors operate at the common frequency of the
slowest DIMM.
• DIMM type: Maximum two types of DIMMs allowed per system and RDIMMs are supported. RDIMM with LRDIMM 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.
19

• 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
• Can mix DIMMs with dierent ranks:
– Maximum of two dierent rank DIMMs allowed in a system
For more information on memory conguration and population, see the Dell EMC PowerEdge T440 Installation and Service Manual at
Dell.com/Support/Manuals.
Memory RAS features
Reliability, Availability, and Serviceability (RAS) features help keep the system online and operational without signicant impact to
performance. RAS can decrease data loss and crashing due to errors. RAS helps in rapid, accurate diagnosis of faults that requires
servicing.
Table 8. Supported RAS features
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 scans the system memory, detecting and
repairing correctable errors.
Recovery from Single
Device Data Correction
(SDDC)
Single Device Data Correction provides error checking and correction that protects against any single
memory chip failure and multi-bit errors from any portion of a single memory chip.
Failed DIMM isolation This feature helps identify a specic failing DIMM channel pair, 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 intrasocket memory fails. The mirrored copy of the
memory is stored in memory of the same processor socket.
Memory address parity
protection
This feature helps 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/performance and can also be used to prevent DIMMs from
overheating.
For information on memory mirroring and sparing congurations, see the Dell EMC PowerEdge T440 Installation and Service Manual
at Dell.com/Support/Manuals.
