Has anyone else encountered issues running PCI Gen 2 or 3 on the Phanteks GPU riser with a 1080Ti? If I enable Gen2 or 3 then the BIOS gets stuck in a reboot loop most of the time. If it does make it to Windows then the screen will blink to black on occasion. Games and graphic benchmarks stutter like crazy and produce about 25% of the normal FPS performance. The same card has been fine since Dec 2017 when directly mounted to the motherboard (Gigabyte Z370 Gaming 7) in Gen 3. It seems stable in Gen1.1 mode though. Wondering if I have a bad riser or it's just an inherent (PCI Gen1.1) limitation of this particular riser.
