Here's where we stand right now:
Friendly reminder to everybody that the bclk setting exists and can possibly let you squeeze in an extra 500mhz on your overclock!

Misc Comments: I'll update my entry if I can find better settings. Max temp was 93C and most tests it was around 70-80C range. I will be remounting the cooler with washers tomorrow, I don't like how it is sitting right now. I feel I should be getting better and more consistent temps across my cores.
Oops! I fixed the cpu model number now.

It seems my vcore had to go pretty high to get stable. I wonder if I should decrease the OC to get it down? Pretty new to overclocking, still learning here. Don't want my CPU to die on me
As you probably know, by changing the base clock you have overclocked the Fclk. That is why it's over 1ghz. What rads are you running?

If set to disabled it is essentially enabling LLC. How much must be set by EVGA themselves. Set it too enabled and run Prime Large FFT test for a few mins and post a screenie with HW monitor.
I also agree, if your doing 4.8 on that voltage that is absolutely awesome. What is the batch number?
Weird that EVGA doesn't have all those options. Removing options is bad.
Although practically speaking, isn't just raising the core voltage similar to using LLC? LLC applies under load, whereas a higher Vcore would apply any time, but it's not THAT big of a deal methinks.

Well I'm hoping the 1.295v is accurate that I have set in my bios! Whenever I run a stress test it jumps up to 1.344v for a reason I'm not sure of yet.
Thanks for looking that up that makes a little more sense. I will enter a support ticket like you said tomorrow and see if I can find anything out. If I do set it to enabled my pc becomes unstable to the point that it won't boot. With the disabled or auto settings it is completely stable. I ran the overnight stress test with it set to the auto. Actually in the bios under the auto option it says that auto adjusts the vdroop depending on cpu frequency. If that info helps at all. I will also post the batch number tomorrow.
It's normal to get higher voltage on load, and higher on harder loads. You're the only one around here with an EVGA motherboard, so it's possible it's a problem that occurs with all EVGA motherboards.
There is an EVGA rep on OCN, maybe you can ping him on this issue.
Hope to see you back with your overclocking settings. 4.9 looks plausible, especially outside of Prime. Then, it would take you to the top of the overclocking chart.

Ok, I will investigate...

So sorry for your loss. Sucks.

Anyways lesson to learn unless you can afford it dont mess with your chip
You're going to worry me. pls no

Yeah, that's past 10C difference and you're not even close to throttling to get that sort of variance, that's not right.

Hope to see your overclock when all is said and done. Until then, good luck with the overclocking!

Not really, and how would we know?
That said, 'daily use' I'm guessing doesn't involve much 100% cpu usage time, so it should be much easier on it than what some other people do with their CPUs...
Don't forget, there is always the bclk. You can always go 4.55ghz.

In-place large FFTs: around 65-70; consumes around ~106W
Small FFTs: instantly jumps to about 85, rises even more; consumes ~136W
Shouldn't my temps be much lower with that Noctua cooler? Did I apply the thermal paste wrong? But, I find 136W pretty huge for a 6700k, thats almost 5820k territory isn't it?
I've listed the temperature and power consumption charts in the OP.

I can't check in my case because I have a 6600k, and HT makes it tougher to pass. :(
What voltages are you getting?

Prime small fft 75c Max 28.7 version.
I'd recommend it.
I'm considering that for over the IHS... so over is that, under is CLU.

I believe I suggested in the OP to disable spread spectrum. Asus uefi also suggests disabling SVID, although that can screw with adaptive/offset voltage modes.
But as to whether that makes a big difference, I don't think so.

Nobody reads the OP m8.

for 1.53v i have to set manual override 1.6v
but other test with set 1.6v max load 1.58v max temp +70cdeg
idle set 1.6v reading on hwmonitor 1.6v temp +30cdeg...
the more the load more vdroop
the less load leass vdrop and less temp...
no llc ... msi z170a gaming m7.... no good
... the mobo don't even can run xmp 3200 2x8gb...
and ek just release new waterblock for vrm and cpu... look very nice.... so need to think again to move to asus hero....
u haz ballz
I only went to 1.5v for benching purposes.
1.6v max load

AIDA64,customx264,prime95v26.6 gives me max temps of 60-62C which is good. I know the 6600k doesn't OC as well as the 6700K, but at 1.35v, 4.5GHZ seems a little low compared to other 6600k benches I've been reading. That said when I tried for 4.6Ghz, I couldn't reach stability even at 1.40v; and I'm not willing to go over 1.4v since temps started hitting 68-70C. Am I doing somthing wrong here, or is 4.5 @1.35v average?
I wouldn't say 6600ks are worse overclockers than 6700ks yet. First and second wave of 6700ks, not a single one hitting 4.9, it's a similar tale with the 6600ks, both at 4.8 max.
Looks like a bum chip to me, and you're not running ultra mega Prime v28.7 either.

I've tried reseating the pump but it did not help at all. I don't think that it is a contact issue in my case as the thermal paste seemed to have spread evenly. I got very similar temps with my Silver Arrow SB-e Extreme so I guess it is more of an issue with the thermal paste under the IHS.
Have you tried pushing down on the pump under load? Also, the H110i GT has a very different backplate to the one that comes with the GTX and it has to be mounted in a particular way. There are loads of pictures showing how it should be placed on the board. Maybe you want to check that too.
Anyway, may I ask you what temps you're getting now?
As for me, my temps are as follows:
IBT, max, 5 mins
4.6Ghz @ 1.31v.
This I think, is the highest temperature variance in the thread so far.

As a friendly reminder to all, step 0 of the OP states to update your bios - it's not new knowledge but should remind everybody... If you run the bios out of the box, it can be older than the launch date of Skylake...
