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
®
X550AT LAN Solution
The motherboard comes with two 10 Gigabit LAN controllers and ports which provide a total
solution for your networking needs. The onboard Intel
®
X550AT 10 Gigabit LAN controllers
use the PCI Express interface and could achieve network throughput close to 10 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 specication 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 efciency, 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 efcient operation.
