I haven't built a personal rig in a long time 5+ years or so. so I'm a little dusty on overclocking.
have a Asus Sabertooth z87 and a 4770k(with Corsair H105, i like the thicker rad) i was looking to get it to at least 4.5Ghz overclock but no luck for me. my question is whats the upper limits on the chips for voltages ive seen that im way out of the normal spectrum here but if i keep the heat down am i good?

4.4> 1.35v(isnt stable at anything lower)stress tests max 74c lowest core 62c and average 70c
i tried to push for a full 1Ghz overclock but im pushing my limits
4.5>1.46v stress test max 86c lowest core 70c and average of 80c
^ that overclock fails around 50 minutes or so into a stress test... but i dont know if i want to go any higher with voltage.. do i just deal with the 4.4Ghz overclock? im bummed, wish i got a better batch.

I think in the Haswell preview, on this site, that they discovered a lot of people have difficulties getting pasted 4.2 ghz, and the upper ceiling seems to be 4.6 ghz. Of course some people have surpassed it - there are exceptions to every rule.

Haswell makes for a good computing platform, it was just a bit underwhelming from an CPU enthusiast perspective. In the realm of small-form factors, it was a good, worthy advancement.

You aren't that far under average... I'm able to get 4.4 @1.25v and that was as high of volts i felt comfortable doing. If i were you i'd go down to 4.2 or 4.3 @1.2-1.3 volts. I have only seen a few people able to get 4.6+ and stay around 1.3 volts.

I think most people have the wrong attitude with Haswell. It's a great CPU.

Very few games benefit from overclocking the Haswell since the bottlenecks are elsewhere (mainly graphics). The Haswell is very power efficient compared to the AMD chips.

Also, 4.5GHz on the Haswell gives more performance than 4.5GHz on previous generations (only slightly over the last one) so compare apples-to-apples.

So, the ability to overclock to say 4.6GHz is really just bragging rights not something that will affect real-world gaming.

So don't be bummed, you've got a great PC.

(I have an i7-3770K and have it at 4.2GHz because I can do that without affecting the Intel Power Management profile so no Voltage change and it runs far cooler that way.)

oh i know that games wouldn't benefit from this overclock(was more of an ego thing lol) indeed I'm not saying that its not a great CPU, I'm merely just stating I've seen so many lucky ones get such a great cpu out of the box (seeing them hit 4.6-4.8 on 1.2~-1.3~ voltages) was just bummed i couldn't get out of the box easy overclock. i had to fight for mine lol.
and i chose to run a EVGA GTX 770 SC im really loving this card i could only overclock that about 65Mgz or so because it came overclocked form EVGA but still super impressed.. Heaven benchmark is at 110fps with settings maxed.

Your CPU lifespan will decrease significantly when overclocked. If you push the limit you may get less than three years though it varies.

I use HANDBRAKE frequently to convert video and there's a HUGE difference in fan noise despite my great cooler (Noctua NH-D14) between 4.2GHz and 4.4GHz because at 4.2GHz I didn't change the Intel Power Management.

My CPU temp went from 68degC at 4.2GHz to 88degC at 4.4GHz because of this so I just stay at 4.2GHz (Asus Z77 Sabertooth and i7-3770K).

*Make sure you don't mess up your DDR3 frequency. It shouldn't be above or below spec (if 1866MHz don't have it at 1600 or below, or 2000+).

I just did THIS:
1) set to XMP
2) Manually change each core to 42 Multiplier
3) ran Memtest
4) ran Intel CPU test (Intel site)

So now my DDR3 is at the rated 2133MHz, my CPU is at 4.2GHz (in Turbo, otherwise lower), and it runs very quiet even under max load.

Anyway, cheers

that's one thing i have noticed that's odd my mem(corsair dominator platinum) is 1866 and i have the xmp profile set for that but when i look up my mem in aida and cpuz it shows it running at 933? when i get home tonight im going to have to play with the settings. im going to bring the cpu down to 4.3 and see if i can get it stable under 1.3 volts, then im going to have to figure out my mem problem.
its only one stick, 8g right now i ordered a 16g kit but the second was DOA so i sent in the RMA, waiting for it back...

Nothing wrong with the ram DDR means double data rate.
933X2 = 1866
I think you should use this guide.

I did and my 4770K runs at 4.4Ghz on 1.2v

Agreed that the reported frequency is HALF.

You MAY have some slight performance loss without the 2nd stick for Dual Channel but it shouldn't be too significant.

I still recommend just setting the Core Multipliers to 42 so that you can maintain full power management and run cooler (thus quieter) under load.

Here's the Intel CPU Diagnostic tool (run anytime you change the CPU or DDR3 memory settings):
