High Density Glass Fabric PCB

What you’ve never understood about your computer is that it is scared to death of water, H2O, humidity or whatever you’d like to name it. And even though you do not see the water, actually there may be lots of excessive moist in the air killing your motherboard silently and slowly. No, your motherboard doesn’t melt when in contact with water like the wicked witch of the west, but it dies of short circuit. Luckily, ASRock has a new High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.

Digi Power

More Precise, More Efficient

Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently and smoothly, so that the stability and lifespan of the motherboard is greatly enhanced.

5+1 Power Phase

The 5+1 Power Phase features sturdy components and completely smooth power delivery to the CPU. It offers unmatched overclocking capability and enhanced performance with the lowest temperatures for PC gaming enthusiasts.

Premium Gold Caps

Top-Class Quality Guaranteed

Premium Gold Caps are luxury capacitors. These 100% Japan-made solid capacitors are sleek, high gloss caps with a premium gold coating representing long life and stable performance.


The Smart Cooling Design

Greater air flow, faster heat dissipation! ASRock X-FAN allows the motherboard to breathe smoothly. It will be automatically activated only when the system rises to a certain temperature under heavy-loading. Normally, ASRock X-FAN will remain deactivated to give users the quietest computing experience.

Crashless BIOS

ASRock Crashless BIOS allows users to update their BIOS without fear of failing. If power loss occurs during the BIOS update process, ASRock Crashless BIOS will automatically finish the BIOS update procedure after regaining power. Please note that BIOS files need to be placed in the root directory of your USB disk. Only USB 2.0 ports support this feature.

Next-Gen PCI-E 3.0 Support

The ASRock motherboards support the Next-Gen PCI-E 3.0! PCI Express 3.0 can maximize the bandwidth for the next-gen PCI Express 3.0 VGA cards, provide ultimate graphics performance.

Get PCI-E 3.0 Benefits
• Higher bit rate – 8.0GT/s
• Higher bandwidth per lane – 1GB/s
• Higher efficiency – 98.5% encoding efficiency
• 100% backward compatible with previous PCI-E 2.0 / 1.0 standard

PCI-E architecture Raw bit rate Bandwidth per lane per direction Encoding Efficiency
PCI-E 2.0 5.0GT/s 500MB/s 80%
PCI-E 3.0 8.0GT/s 1GB/s 98.5%

PCI-E 3.0 requires both a supporting CPU and motherboard at the same time.
Currently Intel® Socket 11 Sandy Bridge-E Processor doesn’t support PCI-E 3.0, but this motherboard is already PCI-E 3.0 hardware ready.
It depends on Intel® CPU to enable PCI-E 3.0. Please check Intel® website for information on future CPU updates and releases.
Graphical UEFI – The Revolutionary BIOS Interface

Unified Extensible Firmware Interface (UEFI) is a revolutionary BIOS utility which offers tweak-friendly options in an advanced viewing interface. Compared with traditional BIOS design, the latest UEFI utility provides lots improved functions. The major features of UEFI include: 
1. Graphical Visual Experience – UEFI provides an improved visual interface with colorful icons and makes your computing environment more versatile to replace the traditional dull BIOS page. 
2. Mouse Enabling – Besides keyboard control, you can freely use mouse to select your ideal settings in UEFI as well.
3. Supports 3TB bootable HDD – UEFI breaks the limitations of 2TB bootable HDD on traditional BIOS. With UEFI, you can enjoy 3TB bootable HDD size.* 

*Windows® Vista™ 64bit or Windows® 7 64bit OS is required.
UEFI System Browser

UEFI system browser is a useful tool included in graphical UEFI. It can detect the devices and configurations that users are currently using in their PC. With the UEFI system browser, you can easily examine the current system configuration in UEFI setup.

AXTU – The All-in-1 Tuning Software

ASRock Extreme Tuning Utility (AXTU) is an all-in-one software to fine-tune different features in an user-friendly interface, which includes Hardware Monitor, Fan Control, Overclocking, OC DNA, IES and XFast RAM. In Hardware Monitor, it shows the major readings of your system. In Fan Control, it shows the fan speed and temperature for you to adjust. In Overclocking, you are allowed to adjust the CPU frequency, ratio and some voltages for optimal system performance. In OC DNA, you can save your OC settings as a profile and share with your friends. Your friends then can load the OC profile to their own system to get the same OC settings. In IES (Intelligent Energy Saver), the voltage regulator can reduce the number of output phases to improve efficiency when the CPU cores are idle without sacrificing computing performance. In XFast RAM, it fully utilizes the memory space that cannot be used under Windows® OS 32-bit CPU.
