AMD StoreMI Technology
A powerful tool that combines the speed of your SSD with the capacity of your hard disk into a single, fast, easy-to-manage drive. SSDs are fast, but expensive, and offer minimal capacity. Mechanical hard drives boast large capacity for a low price, but are much slower than an SSD. AMD StoreMI technology “combines” these two types of storage into a single drive and automatically moves the data you access the most to the SSD, so you get the best of both worlds: SSD responsiveness, and mechanical hard disk capacity. You can also use up to 2GB of RAM as a last-level cache for ultra-fast data.
*AMD StoreMI software is only free with 400-series chipset based motherboards.
Dual M.2 For SSD
Equipped with M.2 slot that supports both SATA3 6Gb/s and PCIe Gen3 x4 Ultra M.2 interface that pushes data transfer speeds up to 32Gb/s, and is compatible with ASRock’s U.2 Kit for installing some of the world’s fastest U.2 PCIe Gen3 x4 SSD.
Dual USB 3.1 Gen2 (Type-A + Type-C)
This motherboard has a pair of onboard Type-A and Type-C USB 3.1 Gen2 ports built on the rear i/o for supporting next generation USB 3.1 Gen2 devices and to deliver up to 10 Gbps data transfer rates.
2oz Copper
It comes with 2 ounces copper inner layers, using only carefully selected copper materials for PCB layers, delivering lower temperature and higher energy efficiency for overclocking.
Super Alloy Motherboard
Premium Power Choke
Compared to traditional chokes, ASRock’s premium power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
Sapphire Black PCB
Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.
2oz Copper PCB
Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.
3 Graphics Outputs
Complete with all three types of most used connectors! Packed with a D-Sub + DisplayPort + HDMI combo. Plus the HDMI port supports 4K resolution.
*Supported with A-Series APUs only.
Triple Monitor
Graphics, graphics and even more graphics! You\'ve demanded for more eye candy, so this motherboard supports Triple Monitor. You may choose up to three display interfaces from the rear i/o to connect monitors and use them simultaneously without installing another graphics card.
*Supported with processors with integrated graphics only.
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.
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.
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.
A-Tuning
A-Tuning is ASRock\'s multi purpose software suite with a new interface, more new features and improved utilities.
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.
Live Update & APP Shop
ASRock Live Update & APP Shop is designed for your convenience. We provide various apps and support 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.
