1.4 Special features
1.4.1 Product highlights
Latest Processor Technology
The motherboard supports Intel Xeon®processor E5-2600 product family in LGA
2011 package with integrated memory controller to support 4 channel DDR3
memory (8 DIMM per CPU). Intel Xeon®processor E5-2600 v2 product family
supports Intel QuickPath Interconnect (QPI) with a system bus of up to 8.0GT/s.
Optimized Intel® Turbo Boost Technology
Optimized Intel®Turbo Boost Technology further optimizes the processor’s
performance and automatically allows it to run faster than the marked frequency if
it is operating below power, temperature, and current limits.
Intel®Hyper Threading
The thread-level parallelism on each processor makes more efcient use of the
processor resources, higher processing throughout, and improved performance on
today's multi-threaded software.
Intel®EM64T
The motherboard supports Intel®processors with the Intel®EM64T (Extended
Memory 64 Technology), feature which allows your computer to run on 64-bit
operating systems and access larger amounts of system memory for faster and
more efcient computing.
1.3 Serial number label
For faster and quicker troubleshooting solutions from the ASUS Technical Support
team, provide the product’s serial number containing 12 characters such as

DDR3 memory support
The motherboard supports the 4-channel DDR3 memory that features data
transfer rates of DDR3 1866 / 1600 / 1333 / 1066 MHz to boost the system’s
performance, and to meet the higher bandwidth requirements of server and
workstation applications. The 4-channel DDR3 architecture also manages trafc
with bandwidth of up to 52GB/s, and reduces voltage thus reducing power usage
and heat generation.
PCI Express®3.0
PCI Express®3.0 (PCIe 3.0) is the PCI Express bus standard that provides
twice the performance and speed of PCIe 2.0. It provides an optimal graphics
performance, unprecedented data speed, and seamless transition with its
complete backward compatibility to PCIe 1.0/2.0 devices.
Intel®82574L Gigabit LAN Solution
This motherboard features the built-in dual server class Intel®Gigabit LAN ports,
which helps reduce CPU usage, thus increasing throughput to achieve highly-
reliable network connections, outstanding performance, and better support for
diverse operating systems.
Intel® 82574L chipset is VMware-certied to support the virtualization technology.
Enhanced Intel SpeedStep Technology (EIST)
The Enhanced Intel SpeedStep Technology (EIST) intelligently manages the
CPU resources by automatically adjusting the CPU voltage and core frequency
depending on the CPU loading and system speed or power requirement.
Serial ATA II technology
The motherboard supports the Serial ATA II 3 Gb/s technology through the Serial
ATA interface and Intel® C602 chipset. The Serial ATA II specication provides
twice the bandwidth of the current Serial ATA products with a host of new
features, including Native Command Queuing (NCQ), Power Management (PM)
Implementation Algorithm, and Hot Swap. Serial ATA allows thinner, more exible
cables with lower pin count and reduced voltage requirements.
Serial ATA III technology
The motherboard supports the Serial ATA III technology through the Serial ATA
interface and Intel®C602 chipset, delivering up to 6Gb/s data transfer rates.
Additionally, get enhanced scalability, faster data retrieval, double the bandwidth of
current bus systems.

1-6 Chapter 1: Product introduction
USB 2.0 technology
The motherboard provides USB 2.0 accessibility, allowing you to experience the
dramatic increase in connection speed from 12Mbps bandwidth on USB 1.1 to a
fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1.
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 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 quiet, cool, and efcient operation.
PIKE (Proprietary I/O Kit Expansion)
PIKE is an on-demand upgrade kit for users. This ASUS unique feature enables
users to choose their preferred I/O solutions. ASUS provides multiple SAS
solutions for different segments and purposes and PIKE saves lots of validation
efforts and hardware cost for end users. Moreover, the special patent design offers
multiple I/O solutions without occupying the PCI slot in 1U system.
