I tried overclocking my EVGA Superclocked GTX 980 and was able to get it at 1500Mhz boost and 1803Mhz memory. I then tried to get a better overclock but was not able to. I tried almost every possible combination of things but for some reason it would not go higher without producing artifacts. I have A LOT of airflow in my case so I do not believe it is overheating (plus the sensors don't say so either), I have my 4790k at 4.9Ghz and my RAM at 2400Mhz so I don't believe there are any bottlenecking issues. Oh, and after I tried all of these combinations to get a better overclock, I tried getting the first overclock (1500 boost, 1803 mem.) and it wouldn't produce artifact-free results. Am I doing something wrong? Is there something I'm looking over? Any help would be appreciated. Thank you!
