Sorry to be the bearer of bad news

Well guess I'm an idiot.    My old X370 supported it, thought this would too. Thank you for the extensive reply! ]]> Thu, 02 Jun 2022 23:03:24 +0000 https://forum.asrock.com/forum_posts.asp?TID=24587&PID=100212&title=x570-pg-velocita-second-pcie-slot-slow#100212 https://forum.asrock.com/forum_posts.asp?TID=24587&PID=100204&title=x570-pg-velocita-second-pcie-slot-slow#100204 Author: Xaltar

The board doesn't support SLI. SLI requires a specific license from Nvidia as well
as support for x8 + x8 (minimum) on the PCIe x16 slots. Your board supports only
x16 + x4 with a 5800x. The reported @ x1 1.1 is only because the second GPU is
not being loaded (because SLI can't be enabled). The x1 1.1 state is default power
saving. ]]> Thu, 02 Jun 2022 17:09:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=24587&PID=100204&title=x570-pg-velocita-second-pcie-slot-slow#100204 https://forum.asrock.com/forum_posts.asp?TID=24587&PID=100192&title=x570-pg-velocita-second-pcie-slot-slow#100192 Author: H-D

I'm trying to SLI two 1080 TIs, but the option for turning it on never shows up. I got to digging and installed GPU-Z and found my second pciE slot runs at 3.0x16 @ x1 1.1.
So I started by swapping the two cards around, issue followed the slot.
I then removed the second card, leaving just top one. It ran as expected. (I don't remember the value.)
Then I installed the card in the bottom slot and it's running at 16 3.0@4 3.0.
I've updated bios to 2.0, reset the bios to defaults, updated chipset drivers, nothing works.
Am I mistaken that slot can run a full speeds?
I'm not a noob, but not a master with all the bios settings.
