Hello techinferno community, I will show what overclocks i use and a few tips on how to overclock with other card you might have. This is for GTX 770m and with Bios Modded, Clevo/Sager laptop np8230 Before Overclock: Heaven Benchmark 4.0 Results: After Overclock: Heaven Benchmark 4.0 Results: Max Temp was 80C with Gpu Stress FurMark on my laptop, may vary. You can push it even further tho but il stay with these sets. I also notice that you need to have a distance between Core Clock and Voltage values, if you see in the pic, it was a 5 value, like core 1001 and voltage 1006 or any higher clock with that distance set, without this rule i would have FPS drops ingame. May vary with other GPU's and Games! Tips on overclocking GPU Memory clocks: You can push it until you reach the point where you don't get artifacts. Example if my stock is 4008 and i push it to 5192 but get artifacts sometimes or always, lower it by 5 and keep testing until you get it stable. Also you can't push it further by increasing voltage. Core Clock: You can push this one until a point where your screen won't freeze, to continue overclocking it you will need to increase your voltage. Take in mind that if you put too much voltage it will cause problems. I experienced FPS drops while playing, even if i stand stood ingame.
