ASRock B450M-HDV R4.0 Motherboard next to its product box

ASRock B450M-HDV R4.0 Motherboard

Experience a new level of performance and reliability with the ASRock B450M-HDV R4.0 motherboard. It works flawlessly with AMD Ryzen-series AM4 processors and supports up to DDR4 3200+ (OC)* memories. Oriented towards DIY enthusiasts, this board comes with one PCIe 3.0 x16 slots, four SATA 3 slots, one Ultra M.2 slot (PCIe Gen3 x4 & SATA 3)* and six USB 3.1 Gen1 ports to meet diverse connectivity needs. It even supports 4K ultra HD and triple-monitor setups. AMD StoreMI Technology unites the speed of SSD and the capacity of HDD perfectly. Quality components installed on the Sapphire black PCB ensure amazing quality and durability.

* Actual support may vary by CPU.

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.

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 of audiophiles.

Great value for the price

Pros: Bought with 3200mhz 2x8 Ballistix RAM, which is running at 3200mhz with no problems. The R5 1600 it was bundled with ran under a stress test for 45 minutes at 4000 mhz and stock voltage. Backed it off to 3950 and 1.25 and it seems solid. Very happy with the board so far.

Cons: The USB port next to the PS/2 headers seems to be flakey. Everything else seems to work like it should.

Board appears to be DOA

Pros: None--- won't post video. So nothing positive

Cons: Board appears to be DOA. It won't post video. I even breadboxed it with no memory or devices... still no video.
Confirmed the PSU worked with another board. So it appears the board is bad.

Not for people who have not kept up with terminology in the last few years

Pros: I do not have this board running yet because I wasted a lot of time and possibly money just trying to figure out what processors would work with this board. If you are already familiar with recent terminology of AMD processors and boards ignore this review.

Cons: Documentation for this ASRock motherboard can be difficult to interpret and there is a serious misleading statement in the brochure part of it.

The best advice I can give is to look at the descriptions of similar MSI motherboards to figure this out quickly, then select an ASRock board and AMD processor if you desire.

Other Thoughts: It has been three or four years since I built my most recent AMD-based system. I wanted to upgrade an existing system using newer components to get a simple system that did not require a display driver card. That goal was a lot simpler to reach back then. My rating of three eggs reflects only the difficulty understanding ASRock's description of the board and the fact that the brochure in NewEgg's information provided by ASRock includes an item that directed me to buy an A-series processor which is actually not compatible with this board and probably damaged it (see the item under the topic "4K Ultra HD" which states that 4K is only available with A-series processors). Another problem is that ASRock's specifications and for compatible processors and other information does not indicate that not all Ryzen processors have built-in display driving capability, and you have to know to look for a phrase like "Radeon Vega Graphics" in the AMD processor description to know it includes the video output driving hardware.
