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.
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.
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.
USB 3.1 Gen2 doubles the data transfer rate
USB 3.1 Gen2 Type-C doubles the charge speed!
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.
Compared to traditional chokes, ASRock's premium 42A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.
High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.
Using only carefully selected copper materials for PCB layers, 2oz Copper PCB delivers lower temperature and higher energy efficiency for overclocking.
This motherboard uses a next generation Hybrid Digi Power design to bring precise control and smooth power. With the ensured efficient and clean power delivery to the CPU, the stability and lifespan of motherboard is also greatly enhanced.
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.
ASRock applied solid capacitors on this motherboard. With these solid caps, this motherboard is allowed to perform more stably and ensure longer lifetime.
Complete with all three types of most used connectors! Packed with a D-Sub + DVI-D + HDMI combo. Plus the HDMI port supports 4K resolution.
*Supported with A-Series APUs only.
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.
A-Tuning is ASRock's multi purpose software suite with a new interface, more new features and improved utilities.
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.
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.

Pros: -Great build quality. An overall contender for the best b450 board in mATX form factor. -Passive cooling for VRM, which no other mATX b450 board has at the time of writing this review. This helps keep them cool when you place your system under heavy load. This also allows for better thermals while overclocking. -Strong overclocking performance, highly comparable to the more expensive Z370 boards. (Some reviewers actually report no overclocking performance difference between this board and more expensive Z370 boards; do some research). This makes this board a good choice for higher end builds despite not being Z370. -4 ram DIMMs (some b450 boards have 2). -Loads of usb ports on the back. -In typical AsRock fashion, top quality make/construction.
Cons: -In typical AsRock fashion, poor BIOS software. Its usable, but not up to the quality of some other manufacturers. Some functions that you would expect from other BIOS softwares simply don't exist, (though everything essential is present). -Make sure this board supports enough drives for your needs; not as many supported compared to full size ATX. -Only 3 chassis fan headers, so for higher end builds using this board that are using 4+ fans, you will need splitters or a fan hub. -If this product has a mail in rebate, read the fine print terms; you may need to have your rebate date stamped & sent within 10 days of your invoiced date (yikes). Better make sure it ships quickly. Mine did come through though, after 3+ months of waiting (not the typical 6-8 weeks).
Overall Review: -MAKE SURE YOUR RAM IS IN THE CORRECT DIMMS. If you have two ram sticks, they should be installed like this: [] [x] [] [x] (x = ram). This ensures you are running dual-channel, which is optimal performance.
