Frequently Asked Questions

Does this motherboard support older AM4 CPUs?
No. The ASRock B850M Rock WiFi uses the AMD AM5 socket and supports Ryzen 9000, 8000 and 7000 Series processors, not older AM4 CPUs.
Does it support DDR4 memory?
No. This motherboard uses DDR5 memory only, with two DDR5 DIMM slots and support for up to 128GB system memory.
Can I use the HDMI and DisplayPort outputs with any CPU?
No. The onboard display outputs require an AMD processor with integrated graphics. CPUs without integrated graphics require a discrete graphics card for display output.
Singular Expert Insight
Choose the ASRock B850M Rock WiFi if you are building a compact AM5 Ryzen system and want DDR5, PCIe 5.0 graphics, Gen5 M.2 storage, Wi-Fi 6E and 2.5G LAN without moving to a larger ATX board. If you need four memory slots or more expansion room, consider a higher-tier B850 Micro ATX or ATX motherboard instead.
