    Hello all,

    I've been wrestling with this for a few days and decided to ask for help. I recently acquired the edp cable and 120 Hz screen, installation took about 2 hours. I cleaned the slave gpu and heatsink, repasted with IC Diamond Paste.

    On the windows desktop I have no issues. Once I start gaming after 20 minutes or so the screen goes black for about 5-7 seconds, flashes desktop, then goes back to the game.

    To rule out driver corruption I ran DDU in safe mode, CC cleaner, and a clean installation of the latest Nvidia drivers.

    Event viewer shows error 4101 and also mentions
    Nvlddmkm Prior to installing the screen I've never seen this message is there.

    Did I miss anything?

    That's the video driver crashing, and restarting. Are you running in Intel/NVIDIA Hybrid, or discrete?

    Discrete. Interesting that it's a video crash, looks like I have more reading to do...

    Since you repasted as well, monitor your temps to see if they are getting too high. The problem could be that one small spot is getting too hot, and it's NOT showing on the GPU temp. When you paste with ICD, it's OK to use more than is needed, as it is non-conductive. And use the ball method vs trying to spread it yourself.

    I will repaste with the ball method as I used the "Pea" technique. Thank you for responding.

    Both methods are the same, just use more than the first time. You'll be able to tell if you used enough when you take off the heatsink and see the coverage.

    Just about any method works fine. Some yield slightly more even spread, consequently slightly better temps. The X/cross method seems to be pretty efficient.

    Speaking of the yield I'll post a photo once I remove the heatsink. I'll be happy if my mistake can help someone else.

    Does disabling SLI make a difference to the crashes? That'll tell you if the issue is with the slave card (and/or sli cable)

    Also check thermal pads are getting good contact, could be a memory chip or vrm getting too hot

    To confirm if SLI disabled does work then put the 2nd card into the first slot and run it.
