Latest processor technology
This motherboard supports the latest Intel®Xeon®Processor E-21xx / Core™i3 series /
Pentium™ / Celeron™ in LGA1151 package, which has memory and PCI Express controller
integrated to support 2-channel (4 DIMMs) DDR4 memory and 1 PCI Express 3.0 lanes.
The Intel®Xeon®E-21xx have improve CPU performance and integrated voltage regulators
making it one of the most powerful and energy efcient 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 specication
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 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). 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 efcient
computing.
DDR4 memory support
The motherboard supports DDR4 memory that features faster clock frequencies and higher
data transfer rates of 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.
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 gure

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 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 two 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 III technology
The motherboard supports the Serial ATA III 6 Gb/s technology through the Serial ATA
interface and Intel®C242 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 specication 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 3.1 Gen 1 (5Gbps) / Gen 2 (10Gbps) technology
The motherboard implements the USB 3.1 Gen 1 / Gen 2 technology with data transfer
speeds of up to 5Gbps or 10Gbps, faster charging time for USB-chargeable devices,
optimized power efciency, 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.
1.4.2 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 efcient operation.

to perform when installing system components. It includes
description of the jumpers and connectors on the motherboard.
Chapter 2: Hardware Information

2-2 Chapter 2: Hardware Information
2.1 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplugthepowercordfromthewallsocketbeforetouchinganycomponent.
• Useagroundedwriststraportouchasafelygroundedobjectorametalobject,such
asthepowersupplycase,beforehandlingcomponentstoavoiddamagingthemdue
to static electricity.
• HoldcomponentsbytheedgestoavoidtouchingtheICsonthem.
• Wheneveryouuninstallanycomponent,placeitonagroundedantistaticpadorinthe
bag that came with the component.
• Beforeyouinstallorremoveanycomponent,ensurethatthepowersupplyisswitched
off or the power cord is detached from the power supply. Failure to do so may cause
severedamagetothemotherboard,peripherals,and/orcomponents.

ASUS P11C-M/4L 2-3
2.2 Motherboard overview
Beforeyouinstallthemotherboard,studythecongurationofyourchassistoensurethatthe
motherboardtsintoit.
Tooptimizethemotherboardfeatures,wehighlyrecommendthatyouinstallitinanATX1.1
compliant chassis.
2.2.1 Placement direction
Wheninstallingthemotherboard,ensurethatyouplaceitintothechassisinthecorrect
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.
2.2.2 Screw holes
Place seven (7) screws into the holes indicated by circles to secure the motherboard to the
chassis.
DO NOT overtighten the screws! Doing so can damage the motherboard.
Ensure to unplug the chassis power cord before installing or removing the motherboard.
Failure to do so can cause you physical injury and damage motherboard components!
Place this side towards
the rear of the chassis
