AM4 Micro ATX for Ryzen 2000 3000 5000

The ASRock B450M/AC R2.0 is a Micro ATX motherboard built around the AMD Promontory B450 chipset and AM4 socket. It supports Ryzen 2000 3000 and 5000 series desktop processors. Four DDR4 slots accept up to 128GB of memory in dual channel mode. Onboard WiFi 802.11ac is included via a vertical M.2 Key E module.

Upgrade from A320 or first gen Ryzen boards

Moving from an A320 board adds CPU overclocking headroom and native support for Ryzen 5000 series without a BIOS flash on older stock. The jump is worth it when you need 3200+(OC) memory speeds on Matisse or Summit Ridge CPUs or want the Ultra M.2 slot running at Gen3 x4 with those processors.

PCIe 3.0 x4 M.2 and SATA 6.0Gb/s limits

The Ultra M.2 socket delivers up to 32Gb/s with Matisse Picasso Summit Ridge Raven Ridge or Pinnacle Ridge CPUs but drops to 16Gb/s with Athlon series. Four SATA3 ports provide 6.0Gb/s each and support RAID 0 1 10. Graphics output relies on the APU and is limited to HDMI 1.4 at 4K 30Hz.

Questions sur cet article

What case and power supply clearances are required for the Micro ATX B450M/AC R2.0 board?

The board uses the Micro ATX form factor with a standard 24-pin ATX power connector and an 8-pin CPU power connector. It fits any case that supports Micro ATX mounting holes and provides room for the rear I/O shield.

Which BIOS step is often missed when installing a Ryzen 5000 series processor on this AM4 socket?

The board must run a BIOS version that includes support for Ryzen 5000 series CPUs. If the installed BIOS is older, the system will not post until the firmware is updated using a supported Matisse, Summit Ridge or Pinnacle Ridge processor.

How long does the bundled WiFi-802.11ac module in the vertical M.2 Key E socket typically last before replacement?

The soldered WiFi module has no specified service interval. If wireless performance degrades, the module cannot be swapped individually; a USB WiFi adapter or PCIe card would be used instead.
