Like the title says i was thinking about overclocking my I7 6800k to 4.2Ghz, but i am new to OC and i was wondering about voltage and ram speed and any other parameter value i need to adjust. I have 4x8gb Kingston hyperx predator 3200hz ram memory, water cooling, and 850W corsair 80+ platinum power suply. And my last question is it even worth it (i'm semi-professional gamer)? Thx in advance.
