The Dell™ PowerEdge™ T620 features the Intel®Xeon®processor E5-2600 product family, which
offers an ideal combination of performance, power efficiency, and cost. These processors provide
high performance no matter what your constraint is—floor space, power, or budget—and on
workloads that range from the most complicated scientific 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, unleashing the
processor’s performance capabilities.
The new Intel Xeon processor E5-2600 product family not only adds new features, but also
improves upon many features of the predecessor Intel Xeon processor 5600 series, including:
Up to two additional cores and up to 8MB more last level cache
More memory—six additional DIMMs and support for up to 32GB DIMMs, which increases
memory capacity from 288GB to 768GB
Intel Integrated I/O has support for up to 80 lanes of PCIe 3.0, which can reduce latency
Faster connections are provided throughout the system with support for DDR3 1600MT/s
memory and 8.0 GT/s QPI
Intel Data Direct I/O (DDIO) allows I/O traffic to skip the main system memory and be directed
straight to the processor cache, which can provide a significant reduction in latency as well as
allowing memory to remain in a low-power state
Intel Advanced Vector Extensions offer up to double the floating point operations per clock cycle
by doubling the length of registers, which can be useful for addressing very complex problems or
dealing with large-number calculations, which are integral to many technical, financial, and
scientific computing problems
Intel Turbo Boost Technology 2.0 delivers up to double the boost than the
previous-generation turbo technology
Continued improvements to both Intel TXT and AES-NI help to better protect systems and data

GPU cards are installed in the PCIe x16 2.0 interfaces, which are slots 2, 4, 5 and 7; slots 5 and 7 only
work with two processors.
With one processor installed, two GPU cards are supported with the following restrictions:
Slots 1, 2, 3, and 4 are available, therefore only two GPUs can be installed in slots 2 and 4
Since double-wide GPU cards occupy two slots, only two can be installed and slots 1 and 3 are
not available
RAID cards cannot be installed with two double-wide GPU cards
With single-wide GPU cards, the PERC H710, H710P, or H810 cannot occupy slots 1 or 3 (PERC
cards have batteries that would overheat if located beside a GPU card)
With two processors installed, four GPU cards are supported, with the restrictions:
Slots 2, 4, 5, and 7 are available
Since double-wide GPU cards occupy two slots, slots 1, 3, and 6 are not available
RAID cards cannot be installed with four double-wide GPU cards
With single-wide GPU cards, the PERC H710, H710P, or H810 cannot occupy slots 1, 3, or 6
(PERCs have batteries that would overheat if located beside a GPU card)
With PCIe SSDs, two GPU cards can occupy slots 5 and 7. Slot 2 is for a PCIe SSD expender card and
slot 4 cannot support a GPU card because of thermal restrictions.
Some operating systems have not been validated to support GPUs. See Table 23 and Table 24 for
more information on operating system support of GPUs.
The Intel C600 chipset is implemented on the PowerEdge T620. For more information, visit

More memory options are available than ever before with the Dell™ PowerEdge™ T620—greater
capacities, higher frequencies, and more flexibility. The T620 supports up to 768GB of memory
(24 DIMMs) and speeds up to 1600 MT/s, providing high performance in a variety of applications.
High memory density means there is no compromise when it comes to virtualization.
Increase your uptime and reduce data loss due to Dell’s focus on reliability, availability, and
serviceability (RAS) features. RAS aids in the rapid and accurate diagnosis of faults which require
service, increasing your memory reliability. System uptime is reinforced with RAS features like
memory mirroring, sparing, and many others.
In addition to supporting existing unbuffered DIMMs (UDIMM) and registered DIMMs (RDIMM), the
T620 supports load reduced DIMMs (LRDIMM), which use a buffer to reduce memory loading and
provide greater density, allowing for the maximum platform memory capacity.

Flexible memory configurations are supported on the T620, ranging from capacities of 2 GB
(minimum) to 768 GB (maximum). The system supports up to 12 DIMMs per processor (up to 24
DIMMs in a dual-processor configuration). The T620 has four memory channels per processor, with
each channel supporting up to three DIMMs.
The T620 supports a flexible memory configuration, according to these basic rules:
Speed: If DIMMs of different 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: UDIMM, RDIMM, or LRDIMM. These
types cannot be mixed.
The following additional memory population guidelines apply to the T620:
Up to two quad-rank (QR) DIMMs and up to three dual-rank (DR) or single-rank (SR) DIMMs may
be populated per channel.
DIMMs must be installed in each channel, starting with the DIMM farthest from the processor.
DIMMs should be installed with largest rank count to smallest. For example, if DR DIMMS are
mixed with SR DIMMs, DR DIMMS should be placed in the lowest DIMM slots, followed by the SR
DIMMs.
For more information on memory configuration, see the Dell PowerEdge T620 Systems Owner’s
Manual on Support.Dell.com/Manuals.
