Need CPU overclocking help

TheToolofLight · Aug 25, 2014

So i ran the gigabyte's program called Easytune. I used AutoTune to overclock my cpu automatically, and it got up to 5,1 Ghz, and then at 5,2 Ghz it crashed, the temps seemed fine. I was wondering, if i overclock to 5 Ghz, what voltage should i use, and if i should do it in the first place. Im running an intel i5 4690k and my MOBO is gigabyte GA-Z97-D3H. My cpu cooler is H100i.

Just start bumping your voltage up in .01 increments until its stable. use prime95 to stress test the rig to make sure its rock solid. just because it doesn't hang while its idling doesnt mean it wont crash or hang the first time you open Photoshop ect..

A couple of things that may help you out.

Firstly I would check out the video from linus tech tips on overclocking devils canyon.

Secondly, I would like to say do not use the auto tune overclocking. Often times they will still push more watts through your system then you need or perhaps want to. 1.3v is pretty much the safe point where you wont be really progressing the shortening of the life span of the cpu.

Basically all you need to do is sync all cores set to a freq, move over to voltages after setting the clock speed and start off with something 4.2 at lets say 1.2volts if you get a blue screen that gives you a 0x124 perhaps boost it up to 1.25v

For validation I use Intel Extreme Tuning Utility. I found that Prime95 acted funny with my i7 4790k, and I also didn't care for OCCT as well. Aida64 is the one Linus recommends however that costs money. And this program is made by the same maker the the CPU itself so I have a easier time trusting it. I ran my test for 24hrs and I with my 4790k got 4.6ghz at 1.24 volts surely I could get higher clocks and maybe 5 ghz however I wouldn't gain much from that.

In conclusion you don't have to do a lot of work with Haswell/Devils Canyon CPU's but please don't use Auto tuning.

I would also recommend HWMonitor for your temp results. Although you can use the one that comes built into Intel extreme tuning utility.

Thanks a bunch ! Im wondering, which should i overclock ? The base clock or the boost/turbo clock ? Does it even make a diffrence ?

Ok, so i think i got 4,6 Ghz clocked at 1.205 V and not planning going any higher, temps are about 70 C max. Thanks for the advice,this helped me out a lot. p.s. I OC'd the boost clock

Your voltage and temps are quite good. I would go with base but if you can do turbo that is good to because you are saving a little bit on power when you aren't using that much power all the time. I ended up doing with Linus did set your base voltage and then turn back after validating and using adaptive but you are good where you are at if you are happy with it. Of course with any overclocking validating it is a good idea just to see how stable it is but at your temps and your voltage you should be okay. Base voltage is how much voltage you are seeing all the time turbo voltage is how much you see at turbo.

I validated it for 12 hours, i hope thats enough. I also cant see the adaptive mode anywhere... or any modes in my UEFI dualbios. I might be blind or its not there. I hope that dosent make a huge diffrence.

Yea 12 hours seems like that is good enough. In terms of Adaptive hmm It should be in the same place where you move the overclock from manual offset and then the 3rd option should be adaptive. If you don't have it your manual voltage is fine. Also keep in mind that with adaptive you are not supposed to run stress tests on your cpu as a lot of programs will ignore your set voltage and add extra.

That actually could be the reason why prime95 is running at 80-95 degrees when i use it to stress test my pc, but IXTU worked perfectly. Ill have a look for it in the bios again, but i sure cant find it.
