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.

10 Power Phase Design

The power phase design offers smooth power delivery to the CPU, unmatched overclocking capabilities, lower temperature for advanced gamers, and reinforced system stability for taking on all sorts of arduous computing tasks.

Digi Power

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.

ELNA Audio Caps

Who says high quality audio is only available on high-end motherboards? ASRock applied ELNA audio capacitors on mainstream and entry-level motherboards! Compared with traditional solid caps, the leakage current of ELNA audio caps is merely 3uA. This is the key to reduce noise level significantly and satisfy even the pickiest audiophiles.

Solid Capacitor Design

ASRock applied solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stably and ensure longer lifetime.

2 x PCIe 3.0 x16 Slots & Flexible PCIe Slots

The two PCIe Gen3 x16 slots are fully compatible with standard graphics cards and other add-on cards. A new flexible PCIe Gen3 x1 slot design* allows users to install add-on cards of all kinds of sizes. (* The bandwidth of your devices will be limited to PCIe Gen3 x1.)

Ultra M.2 32 Gbps (PCIe Gen3 x4 & SATA3

The PCIe Gen3 x4 Ultra M.2 interface pushes data transfer speeds up to 32Gbps. In addition, it also supports SATA3 6Gbps M.2 modules, and is compatible with ASRock’s U.2 Kit for installing some of the world’s fastest U.2 PCIe Gen3 x4 SSDs.

DDR4 OC

Originally an Easter egg, now the hidden option DDR4 OC may be summoned from the UEFI using certain memory modules, such as Samsung or Kingston DDR4 memory DIMMs. It unlocks the hidden potential of those memory modules and maximizes the performance.

UEFI EZ Mode

EZ mode is a dashboard which contains multiple readings of the system’s current status. You can check the most crucial information of your system, such as CPU speed, DRAM frequency, SATA information, fan speed, etc.

Intel LAN

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

Win 7 USB Patcher

Due to chipset limitation, when you want to install Windows 7 on this MB, you may need to use “Win 7 USB Patcher” to create a new ISO file, or check the link “ //www.asrock.com/microsite/Win7Install/” for more details on how to install Windows 7 OS.

A-Tuning

A-Tuning is ASRock's multi-purpose software suite with a new interface, more new features and improved utilities.

Live Update & APP Shop

ASRock Live Update & APP Shop is designed for your convenience. It provides various apps and supports software for users to download. You can also easily optimize your system and keep your motherboard up to date with ASRock Live Update & APP Shop.

ASRock Cloud

ASRock Cloud* technology makes your mobile devices connect to your PC seamlessly and supports multi devices for accessing File Explorer cloud service simultaneously.

Full Spike Protection

Some sensitive digital components on the motherboard are vulnerable to power surges, the excessive current may cause your system to malfunction immediately. ASRock Full Spike Protection includes various technologies to prevent your motherboard’s components from being damaged by these unexpected voltage spikes.

USB Key

In a world where time is money, why waste precious time everyday typing usernames to log in to Windows? Why should we even bother memorizing those foot long passwords? Nobody has time for that! Just plug in the USB Key and let your computer log in to windows automatically.

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.

ASRock OMG (Online Management Guard)

Limit and control your children's time spent on the internet. ASRock OMG (Online Management Guard) 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.

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 ASROCK technical support team.

Easy Driver Installer

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

HDMI-ready

This motherboard supports HDMI (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.

ASRock XFast RAM

ASRock XFast RAM fully utilizes the memory space that cannot be used under Windows 32-bit operating systems. It shortens the loading time of previously visited websites, making web surfing faster than ever. And it also boosts the speed of Adobe Photoshop 5 times faster. Another advantage of ASRock XFast RAM is that it reduces the frequency of accessing your SSDs or HDDs in order to extend their lifespan.

XFast LAN

When Internet Explorer loads very slowly for no clear reason, it's usually due to inefficient management. ASRock is rolling out super-efficient web management in the motherboard industry. XFast LAN is a convenient tool that controls internet related applications easily and efficiently. Creating a perfect Internet environment, all you need is a smart manager. ASRock XFast LAN allows you to enjoy more speed, easier multitasking, enhanced multimedia experience, and more – all without weighing you down.
