## Long description

The ASRock B450M-HDV R4.0 is a micro ATX motherboard based on the AMD B450 chipset with Socket AM4, designed for AMD Athlon and Ryzen processors. It supports up to 32 GB DDR4 memory across two DIMM slots, multiple PCIe and storage options including an Ultra M.2 (PCIe Gen3 x4 and SATA3) slot, SATA III ports and RAID configurations. The board features integrated graphics output support up to 4096 x 2160 (4K) resolution, gigabit Ethernet and a compact micro ATX form factor suitable for gaming and productivity builds.
Advantages
This motherboard offers combined storage flexibility with AMD StoreMI technology that transparently accelerates frequently accessed data by using SSD speed together with HDD capacity, and can use up to 2 GB of system RAM as an additional cache. The Ultra M.2 interface supports PCIe Gen3 x4 modules for high transfer speeds while remaining compatible with SATA3 M.2 devices and ASRock’s U.2 Kit. Additional design features include solid capacitors for improved stability and durability, ELNA audio capacitors to reduce audio noise, a Hybrid Digi Power delivery for precise CPU power control, and Full Spike Protection to guard sensitive components against voltage surges. ASRock’s A-Tuning utility and Live Update & APP Shop provide system tuning and easy firmware/software updates.
Suitable for
Compact gaming PC builds using AMD Ryzen or Athlon processors
Home and office productivity systems requiring 4K display support
Systems needing a balance of SSD responsiveness and large HDD capacity via StoreMI
Budget builds that still require stable power delivery and quality onboard audio

How to use
Install the motherboard into a compatible micro ATX case and fit an AM4-compatible CPU following the processor and cooler manufacturer instructions. Populate DDR4 memory modules into the two DIMM slots, attach storage devices to the M.2 and SATA ports as required, and connect power from a compatible PSU to the 24-pin ATX and CPU power connectors. Use the rear I/O display outputs to connect up to three monitors simultaneously if your processor’s integrated graphics support the selected outputs. Configure BIOS/UEFI settings for boot order, enable RAID if needed, and install the operating system. To enable AMD StoreMI, install the StoreMI software and follow the software steps to combine SSD and HDD storage and, optionally, allocate up to 2 GB of RAM as cache.
Usage recommendations
For best system stability, use matched DDR4 modules and a quality power supply, keep BIOS and ASRock utilities updated via Live Update & APP Shop, and follow recommended thermal and airflow practices. When using AMD StoreMI, back up important data before creating a combined volume and ensure the SSD has sufficient free space for effective caching.
