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 specification
limits. This technology increases performance of both multi-threaded and single-threaded
workloads.
DDR3 memory support
The motherboard supports ECC/Non-ECC UDIMM DDR3 memory that features data transfer
rates of 1600/1333 MHz to meet the higher bandwidth requirements of server and workstation
applications. The dual-channel DDR3 architecture boosts system performance, eliminates
bottlenecks with peak bandwidth up to 25.6GB/s, and dramatically reduces the memory
voltage to just 1.5V compared to DDR2's memory voltage of 1.8V.
Marvell 88E1543 Quad PHY LAN Solution
The motherboard comes with four LAN controllers and ports which provide a total solution for
your networking needs. The onboard Marvell 88E1543 Quad PHY LAN controllers use the
SGMII 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. Get enhanced scalability, faster data retrieval, double the bandwidth of current bus
systems with up to 6Gbps data transfer rates.
M.2 Support
This motherboard features the M.2 slot, which shares bandwidth with the SATA 6Gb/s port
and is dedicated to the operating system.
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 efficient operation.
