1.4 Special features
1.4.1 Product highlights
Latest Processor Technology
The motherboard supports Intel Xeon®processor scalable family which provides compelling
IPC increases for legacy performance improvements, floating point improvement, easier
multi-core programming, and with next-generation processor power management.
Intel®AVX 512
Intel®AVX 512 extends 512-bit vector support for integer vector operations, doubles
fixed point arithmetic throughput, adds support for new vector gather, permutes/blend,
vector shifts resulting in xed and oating-point algorithm improvements. Also, Intel's new
microarchitecture doubles the cache bandwidth at L1/L2 to support higher FLOPS and
contributes to greater performance in signal and image processing applications.
Next Generation of processor power management
Intel®Xeon processor scalable family enhances the processor power management with the
features of Energy Efcient Turbo, Uncore Frequency Scaling, and Per-Core P-state. Also,
the Integrated Voltage Regulator enables generational performance and power improvements
that the standard VR solutions cannot provide.
DDR4 memory support
The motherboard supports DDR4 memory that features faster clock frequencies and higher
data transfer rates of 2133 MT/s to 2666 MT/s (million transfers per second). DDR4 offers a
lower voltage standard of 1.2V that reduces memory power demand and provides improved
performance.
M.2 Support
This motherboard features the Dual M.2 slot, which shares bandwidth with the SATA 6Gb/s
port and PCIE that are dedicated to the operating system.
1.3 Serial number label
Before requesting support from the ASUS Technical Support team, you must take note of
the motherboard's serial number containing 12 characters xxS2xxxxxxxx shown in the gure
below. With the correct serial number of the product, ASUS Technical Support team members
can then offer a quicker and satisfying solution to your problems.

1-4 Chapter 1: Product Introduction
PCI Express 3.0
PCI Express 3.0 (PCIe 3.0) is the PCI Express bus standard that provides an optimal
graphics performance, unprecedented data speed, and seamless transition with its complete
backward compatibility to PCIe 2.0 devices.
Intel®I350 AM2 LAN Solution
The motherboard comes with an integrated quad or dual port Gigabit LAN controller which
provides a total solution for your networking needs. The onboard Intel®I350 Gigabit controller
is designed with high performance and can save platform power with Energy Efficient
Ethernet (EEE) and DMA Coalescing features. It also supports exible I/O virtualization which
enhances network connectivity to more efcient models.
Intel®C620 Series Chipset
The Intel®C620 series chipset supports with enterprise class features which is targeted for
Cloud and Storage applications. It is optimized and validated to work with the latest Xeon®
processor scalable family, compared with the last generation; it also reduces the TDP,
supports USB 3.0 with up to 14 ports for SATA and SSATA thus bringing more features and
benets to the target users.
Serial ATA III technology
The motherboard supports the Serial ATA III technology through the Serial ATA interface
and Intel®C621 / C622 chipset, delivering up to 6 Gb/s data transfer rates. It also provides
enhanced scalability, faster data retrieval, and double the bandwidth of current bus systems.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored to prevent overheating and damage. The system fan
rotations per minute (RPM) is monitored for timely failure detection. The chip monitors the
voltage levels to ensure a stable supply of current for critical components.
1.4.2 Innovative ASUS features
ASUS Fan Speed control technology
The ASUS Fan Speed control technology smartly adjusts the fan speeds according to the
system loading to ensure a quiet, cool, and efcient operation.
