Hi, everyone.

Can anyone help me about something I don not understand, It is about the PCIE port in the mother board x570 Steel Legend, the especification says this :

AMD Ryzen series CPUs (Matisse)
- 2 x PCI Express 4.0 x16 Slots (single at x16 (PCIE1); dual at x16 (PCIE1) / x4 (PCIE4))*

The thing is that whenever I conect a sigle gpu in the PCIE4 port the bandwith is set to x4, as I said , using s single GPU, am I doing something wrong?, does it need aditional BIOS configuration to reach x16 at PCIE4 port?

Hope somebody can help me.

Thanks.]]> Thu, 30 Jan 2020 00:37:51 +0000 https://forum.asrock.com/forum_posts.asp?TID=13549&PID=72361&title=x570-steel-legend-pcie-configuration#72361
