X570M Pro4 PCIe ARI Support

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm looking for a motherboard that can support SR-IOV, and it looks like Alternative Routing-ID (ARI) is a requirement for enabling such functionality.

I noticed that the previous motherboards such as the B450M Pro4 or the X470D4U have specific setting in BIOS to enable PCIe ARI and ACS support, but those functions are no longer present in the latest X570M Pro4 or the B550M Pro4. Does anyone know if those are simply enabled by default if the SR-IOV functionality is turned on? Thanks!
