Hello. I've got the Gigabyte Z87X-UD3H with the i5-4670k with the Cooler Master Hyper 212 EVO.
I've been overclocking to 4.2ghz with Gigabyte's easytune software by using the medium setting under smartboost with these results;

Temperature at max load:

EasyTune Software:

As you can see, with 4.2ghz it is well under stable temperatures. However, i'm worried that these voltages for the cpu are too high, and may damage it over long-term. I'm new to overclocking but i'm wanting to overclock this safely in the BIOS instead of using the easytune software. Hopefully achieving higher speeds and using lower voltages, lowering the temperature.

Help would be appreciated.
 
Seems a little confusing, especially for someone who's new to overclocking and never carried it out in the BIOS before. I've just overclocked to 4.4 using the easytune software and using Heavyload, it's running at 78 degrees max. I'm impressed! However it's using 1.392 Volts which is a little high. I just need a little more guidance on how to overclock and where i should start, and maybe how i should work up.
 
Thanks. Uninstalled software and went into bios. Core speed now at 4.2 at a much lower 1.181 V. Running fine with maximum temperature of around 60 degrees. Definitely much more room for overclocking but will leave it like this for now to test it for a couple of days. I appreciate your help. From this voltage and speed, how would i start to overclock it some more? What increments should i be going up in for both voltage and core?

You'd want to increase multiplier to 4.3, and then Vcore until it's stable enough to boot into windows. Then you stress the machine by gaming or encoding, and increase Vcore until that is stable. I would say jump up to 1.2V to start with, and then 1.21, 1.22 etc.

Rinse and repeat. You can also try playing iwth Vring a bit, mine is at 1.14V, the guide tells you about it.
 
Yeah. It was running at 1.2v but it was crashing after 15-20 mins of full load. I may have a look at getting the voltage down a bit as it lowers the temps a fair bit, just haven't really had time.
 
Sorry to post a bit late, but what would you say is a good Vcore for a simple 4.0ghz overclock on the Costa Rica 3315B355 batch CPU? (4670k)
 
I'm on 4.2 @ 1.015v for an i5 4670k, and my temps have never gone over 45 degrees. There is loads more headroom left, but I'm running my fans all at 5V so all I can hear is my pump. A little annoying but I've had 2 D5's die in a month due to a faulty out put on my psu, so went with a Koolance PMP 500 so I can hear it.
