Hello, I got a 2nd GTX660ti yesterday however whenever I run a game (tested Killing Floor 2, Star Craft 2, Unigine Heaven Benchmark) I keep getting crazy flickering, like there are two images that are slightly out of alignment.

I'm running, WIndows 8.1, i7 3770k, 16gb DDR3 1600mhz ram
One video card is Asus (my original, never had any issues with it) and the other is Gigabyte (the new one)
Nvidia drivers are the latest 358.50

I have tried reinstalling the drivers but the same issue still occurs.

Any ideas on how to fix this?

Hello Archangel,
i have recently bought the same gpu you have (660 ti direct cu II)
and i had these problems when i was on my desktop(=not gaming); horizontal lines --> screen turns black for 1-4 seconds --> screen turns back to windows with the horizontal lines --> the whole proces repeats.
I was searching 8 hours for an answer, and i found a couple of things that worked for me:
1) I disabled the windows(7) aero theme; https://forums.geforce.com/default/topic/525625/geforce-drivers/nvidia-geforce-gtx-650-ti-horizontal-screen-tearing-/2/
2) I changed the values in my registry like this guy did: https://www.youtube.com/watch?v=Zt00C-HXFbA
3) I under clocked my gpu by 10(hz or mhz i dunno) (from 6008 to 5998(=memory clock) &...

4) I changed my power saving mode in my nvidia control panel to maximum performance & changed it in the windows power management + i changed the multi display performance in the nvidia control panel to single display performance

I am soo ducking happy right now.
Oh and i have
CPU: W3580
GPU: Asus GTX 660 Ti Direct CU II
RAM: (2x) 3GB 1066 Mhz
HDD: 120GB SSD + (2x250GB)RAID 500GB
PSU: Stock DELL t3500 525 Watt
OS: Windows 7

But also be sure you have a 650 Watt psu because the 660 ti eats about 150 Watt, and 2 660 ti's eat 300wat MAX, so keep that in mind too.
Your power socket where you plug all your cables could be overloaded.

Hope this helps
