Hi, i am the owner of a asus ROG strix gtx 1050 ti 4 gb OC video card, and I am trying to overclock it. I was able to achieve a good performance improvement without overvolt, but i wanted to push it further so i tried raising the voltage. The thing is, nothing changes: the core clock cannot go above +125 or every game crashes, and the same goes with memory clock, which is stuck at +850. Tried with afterburn and gpu tweak, same result: even with the highest voltage possible, nothing changes. How is this possibile? Here are my specs:
-msi gaming plus z370
-intel core i3-8100, stock cooler
-8gb vengaence lpx single stick
-corsair 650 watt
Thank you for your help

Edit 1: yeah I tried to only raise core clock, but it is always stuck at +125: if you try with +126, furmark runs for a few seconds and then crashes
