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.
