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.

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.

Super Alloy Motherboard

High Density Glass Fabric PCB

High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.

Sapphire Black PCB

Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.

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.

4K x 2K

Composed by a minimum of 3840 x 2160 pixels, which is twice the horizontal and vertical resolution of the 1080p format.

*Supported with A-Series APUs 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

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.


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.

As my previous desktop computer was over 6 years old, and was starting to play up, I felt it was time to bite the bullet and build a new one. I don't play games, and the new mid-tower case doesn't have glass panels, so the motherboard didn't have to support RGB and all that goes with a gaming motherboard. It needed to have an AM4 socket as I wanted to use a Ryzen 5 3600 processor, and 2 DIMMs would be sufficient for a pair of 8 GB of DDR4 sticks of memory. 4 SATA 3 sockets and an M2 socket would be enough storage capacity. The bios would need to have been upgraded at the factory to enable use of the Ryzen 5 3600 cpu. All of the above requirements were met by the ASRock B450M-HDV R4.0 mATX Motherboard. Its well laid out with no tight fits between cpu cooler and memory etc. I have no intention of overclocking, but the BIOS allows for it anyway. Seems well made, and CCL's price/delivery charge was the best I found. In use for a month now, and the new PC is almost exactly 3 times faster when benchmarked against the old one ( and thats still using the old video card.) No doubt I will be looking at what CCL has to offer when the current madness re: price and availability of GPUs quietens down.

The board overall is fairly robust though the bios is incredibly basic. Pro's - Decent build quality - Logically placed connectors - Solid sata ports unlike a brand who begins with a who's kinda sus - Worked with a ryzen 3 3200G oob Con's - Larger than m-atx standard - No llc calibration - Poor overclocking support - Aged unreliable Bios Update tool.
