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. ryzen 7 5800x 32 GB memory SSD, no M.2 drive. |

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. -------------

Well guess I'm an idiot.  My old X370 supported it, thought this would too. Thank you for the extensive reply!
