Open GPUZ 'Bus Interface' click the '?' a window will open click 'start render test'...

1.it should show PCIe X16 4.0 @X16 (1.1) once you start render test it should goto (4.0).

2.If not then if you have anything in your other PCIe slots that might reduce it down to 8x ..

3.Check BIOS that it has not been set to 8x OR 4x... (change it to 'AUTO').

Hi @hanswurst31 

It does, yes. As per the manual:

M.2_1 shares bandwidth with PCIEX16(G5)_2 and PCIEX16(G5)_1. When
M.2_1 is occupied with SSD device, PCIEX16(G5)_2 will be disabled and
PCIEX16(G5)_1 will run x8 only.
