I will start off with the specs first

CPU- i7 6700K Skylake
GPU- Zotac GTX 1070 Amp Edition!
RAM- 2x8 Crucial Ballistix Sport 2400 CL16
MOBO- Gigabyte GA-Z170X-UD3
CPU Cooler- Noctua NH-D15S w/ 2 fans in push pull
PSU- EVGA Supernova 750W B2
Storage- 1Tb Samsung 850 EVO SSD
OS- Windows 10 64bit

Alright, So I am a noob at this overclocking thing and, to tell you the truth, I think I might have lost the silicon lottery on this chip but hopefully I will soon stand corrected. Right now I am only able to get a stable OC of 4.5Ghz at (((WAIT FOR IT)))... 1.4v...?.?.? I was initially trying to go for a 4.6Ghz OC but found out real quick using RealTemp GT with Prime95 and Large FFT's that no more than 5 seconds into it I would get a BSOD. When I do it at 4.5Ghz it runs all the way through both small and large FFT's and surprisingly the max temps only reached 70c at 1.4v. I am just wondering if I am doing something wrong because I see a lot of people going around saying that they have a stable 4.6Ghz, some around 1.236v and others around 1.35v, but mine wont become stable at 4.6Ghz at or bellow 1.4v and I am too scared to push it past that point. Is there something else I need to mess around with in the BIOS to get a stable 4.6Ghz at or lower than 1.4v or am I screwed?

Gigabyte doesn't state these modes. It presumes you know what you doing.
The cpu vcore is where you decide what mode you are in. If you choose your own voltage, then you using manual mode. If you leave it at auto, it is auto/adaptive mode since gigabyte tied them together. If you put normal, then it is in offset mode where is base voltage is 1.2v. You adjust the dynamic vCore to add or subtract from the base 1.2v.

GIGABYTE as I said before does use submenus properly, but it also tends to make unnecessary use of submenus in its BIOS layout. The advanced voltage settings menu for example leads into separate voltage menus for the CPU core, chipset, and DRAM...

Your pagefile need to be bigger. It's still fine to run it at 8gb.

I had RealBench running the stress test at 8GB for an hour and RealBench crashed at 39.39%. Does that mean my OC isn't stable or something or is it the ram? I don't know if it means anything but I don't have XMP enabled, I have it set to auto because the BIOS already recognizes that the ram is at 2400. The only thing that happened was RealBench crashing, I didn't get a hang or BSOD just the crashing, or stopped responding message, of RealBench.

But I already have the dynamic set to +0.050% with a base of 1.300V. If the CPU is requesting more, it is there for it to use. I didn't OC the GPU yet. I want my CPU to last, if I raise the dynamic any further then the CPU will have the ability to request over 1.35V and everyone says safe at max is 1.35V

Test in manual mode so you know what exact voltage your cpu will need to run at 4.5Ghz. Then you can swap to dynamic based on what voltage you found.
You may have an unlucky 6700k.

Then you need 1.4V to be stable with prime95 v 28.9 then. If you don't care about being AVX stable, then use prime 95 v 26.6 or Realbench or AIDA64, not prime95 28.9.

You seem to know a lot about overcklocking. What is a safe range of voltage for a Skylake CPU? Would it be ok for the CPU to be ran at a base of 1.3V and a dynamic of +0.060-0.070V for a max of 1.36-1.37V? I seen in some other forum that intel states there Skylake CPUs can be ran safely at 1.45V, but that is something I don't feel safe with because of everyone's comments on their preference of what is safe on many other threads and forums.

It depends on your view. Personally I prefer to be under 1.35V and my temps to be around 60c or under.
The problem with prime95 28.9 is that it is testing with AVX. This ultimately means you will need a much higher voltage than non- AVX test. For most applications, you do not need AVX so running Realbench/AIDA64 is preferred. Prime95 v26.6 is one option but not any version newer than 26.6 since 26.6 does not test with AVX.
You probably can run your 6700k at 4.5 ghz at 1.35v without bsod for everyday usage. You also should just use small FFT test and not any other test as you want to stress the cpu.

OK, so here is some screen shots of the stress test with RealBench at 4.5GHz, base at 1.300V, dynamic at +0.060V. It ran stable for the hour that I set the stress test for. What kind of gets me is at points Vcore was at 1.320V, 1.332V, 1.344V 1.356V, and even rarely reaching 1.368, all fluctuating but mostly sticking to 1.332V.

Meaning?

I thought LLC conforms to internet if you are talking about Logical Link Control.

What are the best GPU stress testers? I already have Heaven and Valley but heaven seems a little outdated. I can tell because its shadow resolution is extremely low while benchmarking and Valley has been around forever also.
