Hello!

I believe I have a dead PCI Express slot.

I have x2 GTX Titan X that I am trying to run in SLI, unfortunately the second card is simply not being detected.

Cards

What I’ve tested:

1. Tested each card individually in slot 1, both work perfectly.
2. Swapped each card individually into slot 2 to try and boot using this port. PC boots up fine as I can hear the windows login sounds etc, screen stays black and does not turn on.
3. I’ve updated the BIOS to latest version using the tools in the BIOS settings.
4. Have played around with various settings in the BIOS, nothing that I found works.
5. Swapped power cables and SLI bridge. Did nothing.

When I get home from work I plan to clear the CMOS as I’ve read this could help. Apart from that I am pretty lost as what to do.

If I have to RMA the board then so be it, its just annoying to have to mess around with this 

Do you have any other slots populated with PCIe cards? Also do you have a M.2 drive?

Both are unlikely issues especially because you tried slot 2 on its own. While it wouldn't work well, it should work, so IMO dead board is very likely.

Yea, it looks like it! I have a Maximus IV Extreme and it came from the factory with the first and third PCI-E slot malfunctioning. The malfunctions are crashing games, many horizontal and scatter artifacts, but they all go away when I place my GPU on the second or fourth PCI-E slot! I tried updating Bios and everything you did as well, but with no avail. Your PCI-E slots however, as it seems came totally fried. so I would advice in RMA'ing it!

Researching everyday, I get closer and closer to the conclusion that this isn't extraordinary at all, and ASUS does suffer from Quality Control!

Hope I helped!
