I have an EVGA 1080Ti FTW3 and I had a stable overclock at +120 on the Core clock. I used that OC for a few months and there were no problems. Then one day it made everything I tried to do crash (games/benchmarks) and I have no idea why as none of my settings changed. I did some testing (3D Mark) and found that if I disable the Core clock OC then everything is fine, so it isn't the Memory OC. I also found that simply decreasing the core clock multiplier didn't help. It only increases the amount of time the program runs before it crashes. If anyone could provide some answers on why this is happening and the solution I would greatly appreciate it.
