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 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
®
C222 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
®
C222 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.
