I have the GTX 760 as stated in the title. I want to oc it. My default figures are Memory - 1502 mhz, Core - 1020 mhz and Boost - 1085 mhz. I want to oc my memory to +196 and core to +115 to get good performance and some good looking figures. It runs fine and I set the TDP to 110%. I wanted to know whether should I increase it and if yes the exact level. I did it in Afterburner and voltage was grayed out even after enabling it settings. I haven't changed fan settings. Should I do that ? Is this overclocks good ? Temp before oc was 81c and after oc is 82c. Just 1c difference only. My CPU is an oced FX 8320 and 650w PSU and ASRock Mobo. Kindly help me.
