Hey guys! I just builty egpu setup with a Dell Inspiron 15-5557 and a RX 580 4gb. I disconnected my WLAN card that was on the ngff slot connected to the root port #5. But I have an issue: My graphics card needs a maximum speed of 8gt/s,but the root port #5 is being shown as maximum speed 2.5gt/s (note that this is the speed of the port, not the egpu or cable, which have 5gt/s) My root port speeds (hw64) are the following: Intel Skylake-U/Y PCH - PCI Express Root Port #0 [A1/C1]: 8gt/s (PCI Express 3.0) Intel Skylake-U/Y PCH - PCI Express Root Port #1 [A1/C1]: 8gt/s (PCI Express 3.0) (dgpu gt 930m) Intel Skylake-U/Y PCH - PCI Express Root Port #5 [A1/C1]: 2,5gt/s (PCI Express 1.0) (RX 580!) Intel Skylake-U/Y PCH - PCI Express Root Port #6 [A1/C1]: 2,5gt/s (PCI Express 1.0) I read somewhere that it is possible le to alter the speed of these ports in the bios, but since I changed my partition to mbr in order to be able to install the DIY EGPU SETUP 1.3, I've been unable to load uefi bios in my Dell system. My Dell bios version is Dell Inc. 1.1.7, 23/02/2016. My bigger dream is to change this root port speed to at least PCI 2.0,which supports 5gt/s, which is the maximum my egpu adapter can handle. (Gdc exp beast 8.4d,pci 2.0 @5gt/s) Would that be possible?
