“I recently purchased a Dell Inspiron 5675 with Ryzen 1700X, SSD and Radeon RX580. Everything is fine with it except the video card will only connect on the PCIe bus at x8, not x16 as advertised. Anyone else have this issue?”

Yes! I just wrote my review about the Dell 5675 with the Ryzen 7 1800x. It has the same issue. Runs cards in as PCIe 3.0 at 8x. Nothing will run at 16x. I tried everything possible but this motherboard will not support the video card at x16. Google searches prove this to be true about a few high end Dell PC's. Very frustrating but not a real life performance hit.
Sorry, there was a problem. Please try again later.Seeing the same with the 1800x version. Clearly not acceptable to advertise as x16 when it isn't.
Sorry, there was a problem. Please try again later.@Electrolyte - neither slot RUNS at x16, designed/built as x8 only. Dell advertises slots as x16 but in this case that only means you can plug in an x16 card not that it will run at x16. I don't find that acceptable advertising.
Sorry, there was a problem. Please try again later.In the instruction manual https://topics-cdn.dell.com/pdf/inspiron-5675-gaming-desktop_reference-guide_en-us.pdf , it states on page 22: "NOTE: The PCI-Express X16 card slot works at X8 speed only." Lame!
Sorry, there was a problem. Please try again later.The video card has to be plugged into the x16 slot in order for it to run at x16
Sorry, there was a problem. Please try again later.
