4670k overclocking question

Hi,

I am able to overclock my CPU to 4.2 with CPU voltage on 1.25v but after an hour of prime95, my CPU restarts itself. As of now, I'm only changing the CPU multiplier and CPU voltage. Temps are 72C average on full load. Im using Corsair H80i as a CPU cooler

Is there a way to achieve stability?

Please advise

Have you disabled turbo?

Also which motherboard model do you have?

I did not disable turbo. I'm using Gigabyte Z87x-UD3H mobo. Do I need to disable some settings?

Please advise

I would try disabling turbo, may fix it.

I will try that. Let me restate my question. Thanks

Is overclocking to 4.2(max I can do, since temps reach 95C on 1.25v) worth it for gaming? Would there be a significant increase in performance?

If you reach 95 in stress tests, that's ok. If you reach 95 in games then you have to tone down the OC. And yes, the increase in performance from 3,4 to 4.2 is noticeable.

Are you struggling for performance? If you're already getting far above 60 FPS I don't see why you'd need to but to answer your question, there would be a slight increase in performance. In more even more CPU dependent games/multiplayer I think you could see a good 10-20 FPS increase.

I still can't do games since my video card(Sapphire r9 280x Vapor-x ) is not with me yet. Does overclocking with-out a video card affect stability? Please pardon my ignorance...

Best solution

It shouldn't affect stability much more than overclocking with a dedicated card will. I may be remembering incorrectly but I believe the integrated graphics are on the CPU itself so you would just experience higher temperatures from not using a dedicated graphics card. So all it would do is raise the temperature of your CPU but wouldn't affect stability it any other way.

You're not going to see really any improvements from overclocking, and there's no need to, if you're not gaming or doing heavy work (which will require a dedicated graphics card anyway).
