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.
