ASRock B450M-HDV R4.0 AMD AM4 Micro ATX Motherboard

The ASRock B450M-HDV R4.0 delivers reliable performance for AMD Ryzen processors in a compact Micro ATX form factor. Built on the AMD B450 chipset with AM4 socket compatibility, this motherboard supports Ryzen CPUs from Summit Ridge, Pinnacle Ridge, and Raven Ridge series, providing flexibility for various build configurations.

Memory and Storage Performance

Equipped with 2 DDR4 DIMM slots supporting up to 32GB of dual-channel memory at speeds up to 3200MHz (OC), this motherboard handles multitasking and demanding applications efficiently. Storage options include 4 SATA III ports and an Ultra M.2 slot supporting PCIe Gen3 x4 (32Gb/s) and SATA3 drives in 2242/2260/2280 form factors. RAID 0, 1, and 10 configurations provide additional data management flexibility.

Multi-Display Capability

The integrated graphics support from AMD Radeon Vega Series (with compatible APUs) enables triple monitor setups through VGA, DVI-D, and HDMI outputs simultaneously. 4K x 2K resolution support (3840 x 2160) is available with A-Series APUs, delivering sharp visual output for productivity and entertainment.

Connectivity and Expansion

Connectivity includes Realtek Gigabit LAN for reliable network performance, 6 USB 3.1 Gen1 ports (4 rear, 2 front), and 6 USB 2.0 ports (2 rear, 4 mid-board). The PCIe configuration offers 1 x PCIe 3.0 x16 slot for graphics cards and 1 x PCIe 2.0 x1 slot (with Raven Ridge CPUs) for additional expansion cards.

Audio and Build Quality

7.1 channel HD audio powered by Realtek ALC887 codec with ELNA audio capacitors delivers clear sound with minimal noise (3uA leakage current). The Sapphire Black PCB features High Density Glass Fabric construction that reduces gaps between layers, protecting against electrical shorts from humidity. Solid capacitor design throughout ensures stable performance and extended motherboard lifespan.

Power Management and Protection

Hybrid Digi Power design provides precise voltage control and clean power delivery to the CPU, enhancing system stability. Full Spike Protection safeguards sensitive components from unexpected voltage surges, preventing potential damage to your system.

Software and Features

AMD StoreMI Technology combines SSD speed with HDD capacity into a single managed drive, automatically moving frequently accessed data to faster storage. A-Tuning software suite provides system monitoring, overclocking, and utility management through an intuitive interface.
