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.

Cons: A little tight with sata cables on certain GPUs but this is just if you have more than 3 wired.

Overall Review: Second one bought and it runs just as well as the first, no complaints. Easy to use.

Go to MOBO three times now 4/3/2020 10:47:50 AM

Pros: Not a top end, high dollar MOBO, but has the basic functions that I want

Cons: Only drawback was my mistake for not checking clearance of cooler with RAM.
AMD (supplied 2600 processor cooler) logo must face away from sticks of RAM.
Quite the challenge to separate thermal paste stickiness and spin 180 degrees.

Overall Review: Probably the third board purchase with no complaints.
Recommend to the misers out there.
Bang for the buck is to be had for the savvy shopper.

Disappointed 3/10/2020 6:08:08 AM

Pros: Cheap

Cons: Will not work.

Overall Review: Will not work. Purchased one and could not get it to not or show any video. Returned and got another with same issue. Looking at reviews seems there is at least a bad batch. Already contacted ASRock support and followed instructions but still no luck. Will try for a refund and get a different brand.
