I had the same Problem with my other Gigabyte Z87 D3HP, You will probably have to Bios Update.
That solved the problem. Also Gigabyte support advised this to me. :-)

I had try many options on my mobo to keep the spike voltage to 1.36v ot even 1.4 let's say but 1.488v is too much.

Like i posted it here before I do like the offset mode when it keep's my voltage low and my idle at less than 1Ghz for reading is perfect but for everyday i don't like it at all. I thought i was missing something but looks like it is they way it is.

any input to make it more clear would be nice.
thanks for all replay guys.

Is there an adaptive mode or anything you can turn on in bios? Gigabyte boards have adaptive on by default, so even though I set a manual voltage it will go up by .2 but its not a lot.

@Wy2sl0 I agree man, I challenge everyone to do 1 hour of prime95 version 28.1 and still call your chip stable. My first one would do 4.5 at 1.22V in AIDA, IBT, OCCT etc but throwing avx2 at it required 1.34V. That may not matter to everyone though.

Personally, I won't be using anything that requires the use of AVX2, so I'd prefer the lowest voltage I can so I can OC the heck out of my 780s and hopefully not push my wimpy little HX850. I plan on upgrading to a Seasonic X1250 soonish, just gotta convince the wife. XD

Asus z87 "at least mine " has every option. I have tested all of them , only offset down voltage and down clock it. A'm missing anything? I can read and tells you anything on this bios in a quick spit. i already memorized every option there. but I can't make it work the way i want.

It is strange. I ddl, and unzip prime95 28.1. I run it with 4.4ghz @ 1.328v. few minutes when it got fma. it crashed suddently.

it says that it is application faulty.

So I traded out my 4770k for a different batch number (I love Microcenter). Old batch was 309 i believe and I was running 4.6 at 1.4v not entirely stable, but did not really want to push vcore any higher. Got tired of a blah overclocking chip and exchanged it today. Batch number is 314 I think (honestly glanced briefly at it and then threw it back in my system). Boots at 4.6 with 1.2v and no other changes, not stable but can read the internet and junk like that. Seems rock solid so far at 1.23 vcore. Temps usually around 64C but will occasionally spike to 69C for literally 1 or 2 seconds. Chalking that up to just refilling my loop for new chip and having some microbubbles and what not. Based on what I have read from Asus and that 3 step overclocking guide, any chip that boots at 4.6/1.2vcore is an above average chip and good overclocker. Curious if you guys have found this to be true or not?

That's what I understood also. What batch number is that little beauty? I'd love to get a better OCer as I seem to have hit my voltage wall at 4.5. I'm not willing to spend the extra money to get a few MHz, though. XD

My 4670k keeps fluctuating between 4.3 and 4.5ghz.....This is using the newest CPU-Z and Prime95 blend...

You have the C states and EIST enabled in the bios, and this is normal behavior with C states enabled to throttle down to only whats needed for the task at hand. The high performance setting in windows as you see will over ride the c state. If you want a constant 4.5 turn of the c states and EIST. Then windows will not have to be set high perf.

I need some help here. I got a Asus Z87 Deluxe Mobo with a 4770K CPU. When I leave everything default, and only change the setting for the CPU to 'sync all cores' so that they all would boost to 3.9 Ghz under load, I'm already getting a BSOD in BF3 and F1 2012. CPU does not get too hot. Voltage is 'Adaptive' as per default. I can run OCCT, AID64 Prime etc without problems. But running those games gives me a BSOD 124. No sure what's going on?

And this is normal even during P95 100% full load on all cores?

I understand CPUs on "balanced" settings will only ramp up to whatever frequency is required....if a game only requires 3.2ghz, then it will only ramp up to then....but I'm talking about Prime95, which is 100% full cores and taxed to the max
