My monitor has been running at 110hz using the LCD Reduced setting in CRU for years, without any artifacting or other issues. After swapping the cards out I uninstalled my Nvidia drivers in safe mode, reinstalled them normally, used the Pixel Clock Patcher, added my resolutions to CRU, then restarted. However when I boot up Windows I get these weird artifacts which never happened with my GTX 770.

Sometimes it happens immediately when it goes to the lock screen, sometimes it happens when I press anything to get to the password entry screen. After that it doesn't seem to do it while browsing the desktop, watching videos or playing games. Again this is at 110hz, I seem to be having no issues anywhere at 60hz. Did I miss something or enter something incorrectly on CRU? Nothing has changed with my monitor, so I'm guessing it is either a software issue or the GPU itself (though not sure what exactly would be the issue if its the GPU).

That looks like the memory clock is changing when it shouldn't. Try raising the vertical blanking/total and see if that makes it stop.

Just to confirm so I don't accidentally mess something up, you mean keep increasing this 6 number by one until it stops? Do I touch that 144 number at all?

I just don't understand why the same settings in CRU on the same monitor are giving me a problem now when they didn't before. Can the same settings behave differently based on what GPU you're using? Thanks.
