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.

Easy set up, works perfectly. 8/3/2020 3:05:52 PM

Pros: Inexpensive yet capable.

Cons: None noted.

Overall Review: I bought this motherboard because I had a homeless 1600AF. I am putting together a simple gaming pc for a friend. The system booted up first time and recognized all my components. The only thing I had to do was fine tune the fan curves.

I highly recommend this motherboard for any basic system.

Bonus points: it comes ready for Ryzen 3000 CPUs out of the box.

Good Board 7/29/2020 8:54:33 AM

Overall Review: Got it for my dads PC with Ryzen 5 1600AF Sapphire RX570 16GB T-Force Vulcan z and several SSDs and SSHD. I much prefer the B450M Pro4 but it was out of stock tho had i known he wanted to have his dam CD drive AND 3-5 SSD/SSHDs id have got one with far more sata slots... Had trouble with it recognizing a M.2 drive and the other SSDs at diff times thru build and after but finally got it all working. Took egg off due to these issues... But its still a good board.

Ran into a few issues after built-up 7/28/2020 10:18:11 PM

Pros: It's inexpensive

Cons: Since I bought an AMD3400G, I updated the BIOS from the website before it can recognize my CPU. When I finally finished installing Windows, I realized that I could not shut down the computer properly. Every time after I shut down the system, my motherboard and my CPU stay on and I have to force it to shut down every single time.

Another issue I have is that occasionally all the USB ports do not work after I start the computer. I have to restart it to get it working. It has happened a few times within days.

Overall Review: I am not sure if it's a good option

Firmware Incompatible with Major AMD processor line it claims to support. 7/21/2020 11:39:25 AM

Pros: Seems to run fast and well (until my AMD Vega Graphics crashes along with DirectX).

Cons: "THREAD STUCK IN DEVICE DRIVER" blue screen of death and freezing crashes on my Ryzen 3 3200g build in Windows 10 (version 2004)

I really only notice this happening once Ryzen drivers are installed (either through windows update or amd driver software), but from there the crashes happen about once an hour depending on how graphically intense my computer operations are. League of legends on full graphics causes the PC to crash about every 10 minutes while medium-low settings will only crash every half hour; Youtube videos or simple desktop window animations will maybe crash only once every two hours.

According to internet forums where MANY customers of this motherboard are experiencing this EXACT same issue, the culprit is the latest version of ASRock's firmware for this motherboard which crashes with "Raven" and "Picasso" processors types (or something like that). So now I have to downgrade my firmware to an older version than what came from the factory (3.30) to stop my PC from predictably experiencing brutal, hardware-harmful crashes and Windows 10 blue screens of death.

It's unnacceptable for a (perhaps the most) mainstream, entry-level AMD processor line to not work with a mainstream, entry-level motherboard supposedly designed to support that processor line. I bought two ASRock motherboards recently based on their popularity and good reviews, but a basic firmware issue like this makes me question the company's dedication to quality.

Overall Review: Do not use this motherboard with Ryzen 3200g.
