From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hardware info (hwinfo) or similar. Be able to check all voltages, speed and temps while testing new hardware. For example my ARC A770 has little to no info, and shows running at pcie x1.
Edit: mistakingly thought link width was x4, but looking at it again shows x1
Are you positive it’s not running at PCIe x4?
Not sure in Linux, could be a driver or kernel configuration. I don't know a way to double check it. When booting into windows it's at x16. So not a hardware or bios issue.
Try
sudo lspci-vv. It should tell you the negotiated link speed.
