I am trying to over clock my EVGA GTX 970 SC ACX 2.0. I know that my computer is able to be over clocked and It has good cooling. I was using this as a guideline: https://goo.gl/nhc7tM
The user " portofdismay " has the same card as me. So I played around with his numbers and used the main thread and did some testing. I seemed to get 125+ for core clock and 245+ for memory clock. I tested these out on Fallout 4, Dark Souls 3, The Witcher 3, and Rocket League. It seemed to work fine so I put +5 into the voltage to complete it. But the next day I hopped on some games and I got a crash and artifacts on two of my games. so I have brought down -5 on Core and memory and brought up the voltage a bit but now I'm at the step of the picture http://imgur.com/qoS2ETZ
(Voltage +15. CoreClock+110. MemoryClock+225.) Should I keep bringing up the voltage or bring down the sliders..? Also, important not: I'm only looking at the "+110" and stuff. Some people go "put Core boost 1524 and Memory 1915" and stuff, but I'm not seeing any numbers besides the ones by the sliders.. Am I doing anything wrong?
