Dear User/Support,

I am planning to buy an ASRock B550M-ITX/ac ITX-Board.

The situation I am facing is that I want to build in a case which has a PCIe 3.0 Riser Cable included and I want to connect a PCIe 4.0 GPU.

I heard that I most likely do not get any image output when I connect a PCIe 4.0 GPU with a PCIe 3.0 Riser cable to a PCIe 4.0 Board (B550M-ITX/ac) and I do not want to pre-built externally to switch BIOS Settings to 3.0 first.

My question is now: Has anyone built with this board in this configuration and can tell me if it works out of the box (maybe the board has some PCIe Auto-Detection?), or if the BIOS-Setting of this board is on PCIe 3.0 by default?


Looking forward to any hints.]]> Sat, 07 Aug 2021 17:22:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=19373&PID=89631&title=default-pcie-3-0-riser-cable-support#89631
