4 Power Phase Design
Compared to competitors' 3 Power Phase designs on their motherboards, ASRock adds a finishing touch by implementing a 4 Power Phase design and sturdy components for delivering smoother power to the CPU, thus enhancing the motherboard's performance and stability at lower temperatures.

All Solid Capacitor Design
ASRock is determined to use high-quality materials to build the best motherboards, that's why all the capacitors on this motherboard are built with 100% solid capacitors. These solid capacitors bring long lasting durability and ultra stable performance.

UEFI Tech Service
Contact ASRock Tech Service by sending a support request from the UEFI setup utility if you are having trouble with your personal computer. Users may try to choose the category of the issue they have encountered, describe the problem in detail, and then attach an optional picture or log file for our technical support team.

OMG
Limit and control your children's time spent on the internet. ASRock Online Management Guard (OMG) technology allows you to establish an internet curfew or restrict internet access at specified times. Administrators are able to schedule the starting and ending hours of internet access granted to other users.

Dehumidifier
Dampness kills most electronics, so it's a better idea to keep your personal computer dry. Now users may prevent motherboard damages due to dampness by enabling Dehumidifier. When it is enabled, the computer will power on automatically to dehumidify the system after entering S4/S5 state.

Easy Driver Installer
For users that don't have an optical disk drive to install the drivers from our support CD, Easy Driver Installer is a handy tool in the UEFI that installs the LAN driver to your system via a USB storage device, then downloads and installs the other required drivers automatically through the internet. No CD or optical disk drive required!

Fast Boot
With ASRock's exclusive Fast Boot technology, it takes less than 1.5 seconds* to logon to Windows® 8 from a cold boot. No more waiting! The speedy boot will completely change your user experience and behavior.
*The boot time may vary with a different configuration.

Restart to UEFI
Fast Boot is so fast that it is impossible for users to enter the UEFI setup utility during POST. Therefore, ASRock Restart to UEFI technology allows users to easily enter the UEFI setup utility automatically when turning on the PC next time. It is designed for those who constantly need to enter the UEFI setup utility.

HDMI™ - High-Definition Multimedia Interface
This motherboard supports HDMI™ - the High-Definition Multimedia Interface - which is an interface standard for transferring uncompressed video data and delivering multi-channel audio through a single cable. Both video and audio data signals transferred through the HDMI™ interface are digital without being converted into analog, therefore it delivers the richest pictures and the most realistic sounds.
