Do you have any idea what's going on? for both H13SSL-N and H14SSL-N Supermicro writes different M.2 PCIe Gen versions in different places, including the manuals, to the point where I'm completely confused.

H14SSL-NGen 4Gen 4Gen 5

@i386 you have an H13SSL-N, are the M.2 slots Gen4 or Gen5 in yours?

I don't know I don't use m.2 ssds. I'm using optane u.2 connected via retimer (my mcio cables don't "stick" with the onboard mcio connectors) or directly in the pcie slot (radian rms-200)

H14SSL is the (explicit) 500w tdp version of h13ssl and relatively new., I think supermicro has a few typos on the page and in the manual.
