Hi. I have been a follower of SFF.network for a number of years, and have been inspired to build (another) custom ITX build. I have a very specific query re: B550 chipset and use of PCI-e 4.0 SSDs when you have to restrict the PCI-e mode for the Graphics card to Gen 3.0. As is often the case, I use a (30cm) PCI-e riser cable for my build, but it's only Gen 3.0. Leaving my Gigabyte B550i motherboard in "auto" mode for graphics PCI-e results in significant instability (I'm lucky to get the PC to boot 5% of the time). So, does the fact that I have set PCI-e to Gen 3.0 for the graphics card mean that I can't use a PCI-e Gen 4.0 m.2 SSD (such as a Samsung 980 pro) and still achieve the benefits of a PCI-e 4.0? If so, is my only option to upgrade the PCI-e riser (as I'm loathe to spend >£70 on a cable!) or are there other options?
