I just successfully over clocked my i5-4670k to 4.8GHZ at 1.275 volts on my ASUS Z87-PRo motherboard. I'm reading a lot of post online and it seems people are having trouble even getting above 4.3GHz. I am fairly new to all of this so I am just worried I did something wrong or is this just beginner's luck? What are the cons for having a high overclock and should i bring it down? Is 4.8 too high?
