I install the system with 1600 CPU, NVMe M.2 with Win10 and two Rx470 cards.

The problem is that my second GPU wont show in the device manager and my third screen wont turn on.

I need to change my pcie lane configuartion from x16/x0/x0 to x8/x8/x0.

Big thank

Dear MichaelTn,

Greetings, this is ASRock TSD.

With AMD Ryzen series CPUs, please be notice with the following specification.

1. It supports 2 x PCI Express 3.0 x16 slots (single at x16(PCIE2); dual at x16(PCIE2) / x4(PCIE4))

2. Supports NVMe SSD as boot disks. If M2_1 is occupied, PCIE4 will be disabled.

Specification:

Regarding your system configuration, when installing an NVME M.2 device in M2_1 socket, the PCIE4 slot will be disabled.

So the second VGA card which is connected to PCIE4 slot will not able to use.

Thanks!

All the best,

ASRock TSD
