So, to preface this: my MoBo is a GA-Z77X-UP4 TH from Gigabyte.
My BIOS was no longer allowing me to access it (would hit delete and get a black screen that didn't disappear), so after some light troubleshooting I decided to do a CMOS reset. I did what the manual said for the jumper (two pins, power off, and place metal object between two to make contact) and TADA I had access to my BIOS screen again. But, when I launched into Windows I noticed only one of my 980Tis was being detected by the PC.
To troubleshoot I swapped the card in the second lane with the first and let it run solo to ensure it wasn't dead. Sure enough the GPU was fine. I then placed the GPU that was formerly in the first lane into the second one. It was not detected.
Did the CMOS disable my second PCI-E lane? Everything else is working fine, and I can't find anything in the BIOS for PCI other than what the display launches from. I'm not exactly new at this, but this is a first, and I somewhat doubt doing the CMOS reset nuked the lane. Should I have unplugged components before the reset, and if so, should I do so and reset again to bring that lane back to life. I kinda, sorta, maaaaaybe need SLI to run most of my games at 4k resolution and max settings.
I know, life is rough . . . >.>
