Greekbull Posted April 23, 2015 Posted April 23, 2015 (edited) Hey guys wanted to get some possible ideas. I just purchased another EVGA GTX 970 SSC to go SLI for some extra horsepower for the new cockpit I built with a 4K monitor and another monitor for UltraMFCD(He's already stated he will have it working with Fullscreen mode so I'm good there). Anyway I got the second card installed and I'm having issues with a strobe effect green screen intermixed with my regular graphics. So much it is unplayable. I think it is likely the SLI Bridge. Waiting for another to arrive tomorrow. Unfortunately I didn't have a place to buy one local. I tested both cards in both PCI slots of my ASUS Z97-A MB and they work fine individually. I updated drivers. Checked BIOS to make sure both are set at PCI Gen 3. Anything I'm missing? Does it sound like the SLI Bridge to you guys?

infernus1986 Posted April 23, 2015 Posted April 23, 2015 I have heard of the cheaper SLI bridges doing this Also not having the proper cables or using the wrong type of port for certain displays can do this. What is your current monitor, cable, port setup FX-8320 8Gb R9-280 X-55 Opentrack [sIGPIC][/sIGPIC]
Greekbull Posted April 23, 2015 Author Posted April 23, 2015 I'm using at 4K 50" Vizio connected at 3840x2160 60Hz with a HDMI 2.0 Cable connected from the HDMI 2.0 output of one of the GTX970s. It works perfect with each card individually at 4K with about 25-50FPS. Not sure on the Port....how do I check that?...and thanks for the response!

_Dredd Posted April 23, 2015 Posted April 23, 2015 Ahh the green goblins. Most likely an SLI bridge issue. Make sure contacts are clean on SLI connectors on the card; and try another bridge. Didn't you get an SLI bridge included in the box with your card ?

None with the cards just one with my ASUS MB and it had a kink in it. I'm pretty sure that was the issue. I really hope this new bridge arriving from Amazon tomorrow solves my issues.

_Dredd Posted April 23, 2015 Posted April 23, 2015 Kinks aren't good. Have an old mobo box around with another possibly inside? Otherwise; best 'o luck with new one.

rcjonessnp175 Posted April 23, 2015 Posted April 23, 2015 Definately sounds like sli bridge. But just in case their is two spots on your cards you can attach the sli bridge try changing the spots. That actually worked for my 980's I7 4770k @ 4.6, sli 980 evga oc edition, ssdx2, Sony 55 inch edid hack nvidia 3dvision. Volair sim pit, DK2 Oculus Rift.
Greekbull Posted April 23, 2015 Author Posted April 23, 2015 (edited) Solved my problem!!! I did some extensive searching. Appearantly Nvidia GTX 980s and 970s are having an SLI issue with 4K TV 60Hz HDMI 2.0 connections. Nvidia has acknowledged it and is working on a fix. the 980s and 970s work perfectly at 60Hz by themselves but have a crazy green flicker or just a flicker in SLI at 60Hz. I found a suggestion to adjust the refresh from 60Hz to 59Hz and bam! Everything is working perfectly! FPS in DCS at 4k is now in the 60s-80s Loving it! So if anyone else runs into this hopefully this will help you!
