Overview
The ASRock B450M-HDV R4.0 is a Micro ATX motherboard built around the AMD B450 chipset (AMD Promontory B450) and AMD AM4 socket, making it compatible with AMD Ryzen CPUs including Summit Ridge, Pinnacle Ridge, Raven Ridge, and select AMD Athlon series processors. Its 6-phase power design supports CPUs with a TDP of up to 105W, offering stable power delivery for everyday and moderately demanding workloads. Memory support covers two DDR4 DIMM slots operating in dual-channel configuration, with a maximum system memory capacity of 32 GB. Supported speeds vary by CPU generation — Pinnacle Ridge and Summit Ridge CPUs support DDR4 3200 (OC), 2933 (OC), 2667, 2400, and 2133 in ECC and non-ECC unbuffered configurations, while Raven Ridge CPUs support non-ECC unbuffered memory at those same speeds. Gold contacts (15μ) in the DIMM slots contribute to connection longevity. For graphics output, the board provides three rear-panel display options — D-Sub (up to 2048×1536 @ 60 Hz), DVI-D (up to 1920×1200 @ 60 Hz), and HDMI (up to 4096×2160 @ 24 Hz or 3840×2160 @ 30 Hz) — enabling triple-monitor configurations when using a Ryzen APU with integrated AMD Radeon Vega graphics. Storage is handled by four SATA3 6.0 Gb/s connectors with RAID 0, RAID 1, and RAID 10 support, plus a single Ultra M.2 socket (M Key, 2242/2260/2280) that accommodates both SATA3 and PCIe Gen3 x4 (up to 32 Gb/s) NVMe modules when paired with Summit Ridge, Raven Ridge, or Pinnacle Ridge CPUs. Audio is delivered by the Realtek ALC887 codec with 7.1-channel HD audio, ELNA audio capacitors, and surge protection. Networking relies on a Realtek RTL8111H Gigabit LAN controller (PCIe x1) supporting Wake- LAN, PXE, Energy Efficient Ethernet 802.3az, and ESD/lightning protection. Rear I/O includes one PS/2 port, one D-Sub, one DVI-D, one HDMI, two USB 2.0 ports, four USB 3.1 Gen1 ports, one RJ-45 LAN port, and HD audio jacks. Internal connectivity adds two USB 2.0 headers (four ports total), one USB 3.1 Gen1 header (two ports), CPU and chassis fan connectors, a TPM header, COM port header, and front-panel audio connector. The 128 Mb AMI UEFI BIOS supports Plug and Play, ACPI 5.1, jumperfree operation, and DRAM voltage adjustment.
