I just received my new gaming PC two weeks ago, and I will shortly receive the HD 5850 and the Noctua NH U12P that go with. I'd like someone to tell me a little about overclocking because I do not know very well there. What I'd like to do would be to overclock my i5 750 to about 4.0 GHz, which, from what I read in several articles is easily achievable with a good motherboard and a good cooler! I would also (possibly) go further, but only to the extent that my system is stable, or it does not lead to an over consumption of energy, and it does not affect the longevity of my components. I have a ASUS Motherboard P7P55D which was purchased for this purpose! It comes with a program that allows me to change the FSB in real time (I tried it once, for the underclocker proc when I saw that easily rose to 75 ° C (with cooler Intel), But the PC froze and I had to cut the juice ) but I do not know what it's worth! Is both a manual for the bios? I would also like to know what temperature you advise me not to exceed? I prefer the durability performance, I do not want to prematurely fatigue to win my CPU 133 MHz. From what I understood after, for O / C on a platform 1156, we must increase the FSB. Would just increase the tension has mounted in the support rate for the system remains stable, it is that? Have you an idea of the tension applied to keep a stable i5 750 has 4.0 GHz, and without any to burn out? It is there to take special precautions before embarking on the inside? Should I activate the turbo mode or other functions of the CPU before the O / C?
