1.4 Special features
1.4.1 Product highlights
Latest processor technology
This motherboard supports the latest Intel®Xeon®Processor E3-1200 v3/
CoreTM i3 series in LGA1150 package, which has memory and PCI Express
controller integrated to support 2-channel (4 DIMMs) DDR3 memory and 16 PCI
Express 3.0 lanes. The Intel®Xeon®E3-1200 v3 have improve CPU performance
and integrated voltage regulators making it one of the most powerful and energy
efficient CPU in the world.
Intel®Turbo Boost
Intel®Turbo Boost automatically allows the processor to run faster than the marked
frequency if the processor is operating below its power, current, and temperature
specification limits. This technology increases performance of both multi-threaded
and single-threaded workloads.
Intel®Hyper Threading
The thread-level parallelism on each processor makes more efficient 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). The Intel®EM64T feature allows your computer to run on
64-bit operating systems and access larger amounts of system memory for faster
and more efficient computing.
DDR3 memory support
The motherboard supports ECC UDIMM DDR3 memory that features data
transfer rates of 1600/1333 MHz to meet the higher bandwidth requirements of
server and workstation applications. The dual-channel DDR3 architecture boosts
system performance, eliminates bottlenecks with peak bandwidth up to 25Gb/s,
and dramatically reduces the memory voltage to just 1.5V compared to DDR2's
memory voltage of 1.8V.
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 as the figure 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.

ASUS P9D-E/4L 1-5
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®I210AT LAN Solution
The motherboard comes with four Gigabit LAN controllers and ports which
provide a total solution for your networking needs. The onboard Intel®I210AT
Gigabit LAN controllers use the PCI Express interface and could achieve
network throughput close to Gigabit bandwidth.
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®C224 chipset. The Serial ATA II specification
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
flexible cables with lower pin count and reduced voltage requirements.
Serial ATA III technology
The motherboard supports the Serial ATA III 6 Gb/s technology through the
Serial ATA interface and Intel®C224 chipset. Get enhanced scalability, faster
data retrieval, double the bandwidth of current bus systems with up to 6Gbps
data transfer rates.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0 specification
that dramatically increases the connection speed from the 12 Mbps bandwidth
on USB 1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible
with USB 1.1.
USB 3.0 technology
The motherboard implements the USB 3.0 technology with data transfer speeds
of up to 5Gbps, faster charging time for USB-chargeable devices, optimized
power efficiency, and backward compatibility with USB 2.0.
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.

1-6 Chapter 1: Product introduction
1.4.2 Innovative ASUS features
ASUS Fan Speed technology
The ASUS Fan Speed technology smartly adjusts the fan speeds according to
the system loading to ensure quiet, cool, and efficient 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 Slot 6 in a 1U system.
ASUS MIO Audio card
The ASUS MIO audio card is a discrete 8-channel high definition audio (High
Definition Audio previously codenamed Azalia) CODEC that enables the clearest
high quality audio output. It has jack-sensing feature, retasking functions, and
multi-streaming technology that simultaneously send different audio streams to
different destinations for high-end sound quality.
