  • Maximum Memory Supported256GB

Option B850M Riptide WiFi

Struck-through versions exist but are not stocked here.

  • Supports Ryzen 7000, 8000 and 9000 series CPUs on AM5 socket
  • 12+2+1 phase Dr.MOS power design with 1000uF 20K capacitors
  • Four DDR5 slots up to 8000+(OC) with AMD EXPO and Intel XMP 3.0
  • PCIe 5.0 x16 plus three M.2 slots including Gen5x4 and Gen4x4
  • Realtek ALC1220 7.1 audio with Nahimic and Dragon RTL8125BG LAN

Micro-ATX AM5 Board With Three M.2 Slots

This board suits builders choosing a Ryzen 7000, 8000 or 9000 CPU and needing four DDR5 slots, a PCIe 5.0 x16 slot and three M.2 sockets. The 12+2+1 phase Dr.MOS layout and 20K capacitors give stable power for high loads.

Straightforward Install With Standard Clearances

The micro-ATX footprint fits most cases using regular standoffs and the I/O shield is pre-mounted. CPU power uses an 8-pin connector and the 24-pin ATX sits at the usual edge. Tall coolers can block the first DIMM slot, so check cooler height before ordering.

Compact Builds Needing Triple M.2 And 256GB RAM

Enthusiasts wanting up to 256GB DDR5, three M.2 drives and 7.1 audio in a smaller chassis will match well. Users requiring more than one PCIe x16 slot or more than four SATA ports should look at a full-size ATX alternative.

Highlights

  • Supports Ryzen 7000, 8000 and 9000 series CPUs on AM5 socket
  • 12+2+1 phase Dr.MOS power design with 1000uF 20K capacitors
  • Four DDR5 slots up to 8000+(OC) with AMD EXPO and Intel XMP 3.0
  • PCIe 5.0 x16 plus three M.2 slots including Gen5x4 and Gen4x4

Questions about this item

How can I confirm the ASRock B850M Riptide WiFi is running correctly after first boot?

Enter the BIOS and verify the CPU is detected as a Ryzen 7000, 8000 or 9000 series processor, that all four DDR5 slots show the installed capacity totalling up to 256 GB, and that the primary M.2 socket reports a Gen5 x4 link.

What comes in the box with the B850M Riptide WiFi and what must I source separately?

The motherboard includes an I/O shield, SATA cables, M.2 screws and a quick-install guide; you must purchase an AM5 CPU, DDR5 memory modules, storage drives and a graphics card separately.

Which M.2 socket should I use for the fastest NVMe drive on this board?

Use the CPU-attached Blazing M.2 socket (M2_1) which supports PCIe 5.0 x4 at 128 Gb/s for a 2280 drive; the chipset sockets run at Gen4 x4 or x2 speeds.
