Hey guys I was playing Far Cry 3 the other day and noticed my frames were dropping below 60 on ultra so I decided to try and overclock my GPUs just to squeeze out any frames possible. I loaded up MSI afterburner and read a few guides on overclocking and looked up some overclocks people were getting on their 270x. I started by putting the Power Limit to +20%, and put the core clock at 1150. No matter what I do, my cards will not go above 1050 MHz. Which I find funny because the boost clock is supposed to be 1100MHz but even under 99% load I never saw them go above 1050MHz. I even tried tweaking the memory clock but that wouldn't budge either. This is my first time overclocking, so is there something in the options I should check or am I just missing something? I also disabled AMD overdrive as I read some people had issues with that, but nothing else on google helped me. Any help is appreciated.
