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.

2 x PCIe 3.0 x16 Slots
PCIe Gen3 x16 slots that are fully compatible with standard graphics cards and other add-on cards.

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.

Ultra M.2 32 Gb/s (PCIe Gen3 x4 & SATA3)
The PCIe Gen3 x4 Ultra M.2 interface pushes data transfer speeds up to 32Gb/s. In addition, it also supports SATA3 6Gb/s 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.

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!

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.

Supports DDR4 3866+ (OC)
Supports the latest DDR4 memory modules and most extreme memory performance!

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.

Flexible PCIe Slots
A new flexible PCIe Gen3 x1 slot design that allows users to install add-on cards of all kinds of sizes.

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, 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.
