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.

Multiple Filter Cap (MFC)
By combining the power and advantages of three different kinds of capacitors, including the DIP cap, POSCAP and MLCC, Multiple Filter Caps allow hardcore overclockers and enthusiasts to overclock their motherboards to extreme levels without having to worry about the other hardware components.

Advanced 12 + 2 Power Phase
This motherboard is designed with a 12 + 2 Power Phase design. It features sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capability and enhanced performance with the lowest temperature for advanced gamers as well.

DDR3 2450(OC)
This motherboard unlocks maximum memory performance, coming with 4 DIMM slots for dual-channel memory, supporting up to DDR3 2450 (OC) MHz!

Dual-Stack MOSFET (DSM)
Dual-Stack MOSFET (DSM) is an innovative new design of MOSFETs. The silicon die area is increased by stacking two dies into a MOSFET. The larger the die area, the lower Rds(on). Compared to traditional discrete MOSFET, DSM can provide larger die area and lower Rds(on), so the power supply for CPU Vcore is more efficient.

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.

3-Way SLI/3-Way CrossFireX
Equipped with 4 x PCIe 2.0 slots, this motherboard supports NVIDIA 3-Way SLI and AMD 3-Way CrossFireX, providing ultimate multi-GPU performance.

Intel Gigabit LAN
Intel LAN provides the best throughput performance, lower CPU utilization, enhanced stability and is able to deliver ultimate network experience to users!

XFast 555 Technology: XFast RAM / XFast LAN / XFast USB
XFast RAM
- Fully Optimize Memory Usage.
- 5X Faster for Photoshop Execution: XFast RAM will create a virtual disk from the system memory to boost the performance. For Photoshop, It can even perform 5X faster than before.
XFast LAN
- Faster Internet Access.
- Lower Latency In Game: XFast LAN can lower latency in the game after setting online game priority higher.
XFast USB
- Boosts up your USB Speed.

C.C.R. (Combo Cooler Retention Module
The unique combo cooler retention module greatly improves heat dissipation and is backward compatible with AMD previous AM3/AM2+ coolers.

8 USB 3.0 (4 Front, 4 Back)
Rich storage options! This motherboard offers 8 USB 3.0 (4 from onboard header, 4 from rear I/O) and bundles an exclusive front USB 3.0 panel to facilitate computing environment.

Hi-Density Power Connector
Hi-Density Power Connector features a solid square-pin design. ASRock motherboard is equipped with High-Density Power Connector for the CPU power connector. The optimized design can reduce 23% power loss and decrease connector temperature up to 22°C.

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.

Dehumidifier
Users may prevent motherboard damages due to dampness by enabling “Dehumidifier Function”. When enabling Dehumidifier Function, the computer will power on automatically to dehumidify the system after entering S4/S5 state.

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.

ASRock OMG (Online Management Guard)
Fast, Easy and Free – ASRock 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. Normally, ISPs (Internet Service Provider) will charge for internet curfew service, which controls “all” the PCs connected at home. However, ASRock OMG is a free tool for controlling internet access of each single PC. Parents can easily control internet access through the BIOS setup to protect their kids from using the Internet at inappropriate times, and meanwhile, enjoy their own internet space.

Easy RAID Installer
Easy RAID Installer can help you install the RAID driver easily without floppy drive. It can copy the RAID driver from a support CD to your USB storage device with just one simple click in UEFI setup.

Internet Flash
Updating the UEFI is easier than ever with ASRock Internet Flash! Simply by a few clicks it searches for available UEFI firmware updates from ASRock's servers, then it automatically downloads and flashes the latest UEFI file within the UEFI setup utility without having to enter Windows OS.
