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 optimal graphics performance,
unprecedented data speed, and seamless transition with its complete backward
compatibility with 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 Serial ATA II 3 Gb/s technology through the Serial ATA interface
and Intel ® C22x 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 ® C22x 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
CPU temperature is monitored to prevent overheating and damage. 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.
