Hi there,I noticed that all my GPU operate at PCIe 1.1=2.5GHz instead of PCIe 2.0/3.0.

Link speed might be set dynamically depending on load. You may do something like:
watch -n1 'lspci -vv -s 01:00.0 | grep Lnk' and then find some task to load the GPU. -- Sarunas Burdulis Systems Administrator, Dartmouth Mathematics math.dartmouth.edu/~sarunas · https://useplaintext.email ·
