5. CPU overclocking
I start overclocking part before I will show test results. In the graph are already included the results of overclocking CPU ... I have used the popular AIDA stress test. I do not recommend Prime95 stress test for Skylake, nor indeed for any other CPUs. That test is oversized in burning of CPU and power cascade. It generates alspo a lot and unreal errors (bugs) ... It is my personal opinion after the experience of forums around the world. Better to do with OCCT test, Intel stress test or AIDA stability test. Skylake overclocks very well. Since the CPU main IR controler is a back out to the processor, and it is reduce the heating. Also, useable voltage range is now excellent and cooling down the CPU is well. And even though it is made on new 14nm technology! The technology size of the production that much does not mean and the problem are and has always been temperatures. This processor matters, unless there overdo the vcore ... but I can say that with a better cooler is Skylake i7 on 1.4V safe for long time and for some tests you can jump up to 1.5V (as example hwbot prime test, Cinebench redner,...). Temperatures should not, however long exceed 90 C at cores. Skylake comes clocked better than Haswell. The whole point is simple, based on a voltage CPUx turbo multiplier. The rest can fine-tuned via BCLK, which is on „K processors“ fully open (perhaps so you can try combination of 150MHz BCLK and turbo multipliers + to do reduce dividers cache + memory frequency). For more xxperienced users Im recommending also set up small things like cache frequency and cache voltage, SA voltages for high memory clocks and a of course, we must not forget at LLC aka load line calibration. On Asus MBs LLC works best at level 4 or 5. You can play with the VRM settings more.
But to my result. Processor Ive got stability at a high frequency of 4747 MHz at all cores. I think that is a very good result. Suffice CPU voltage only 1.36 V. As you can see, the temperature in the load are very good.
I share my BIOS settings for 4747 MHz, you can try using some ROG motherboard with Skylake with this values...

Power consumption – how much? There has Skylake luxury, of course, consumption in the graph is a load of CPU in CINEBENCH and GPU Radeon idle, but as you can see, the increase in power consumption is minimal assembly against a baseline. More would probably grew up from approximately 1.45V VCore ..

7.Overclocking bonus - AIR vs LN2
7.1 AIR benchmarking overclocking
Quickly I tried what processor and the motherboard can handle. Maximum in render CINEBENCH I got there 4900 MHz, 5 GHz failed to even higher voltage ... Even so, it is an above average piece of silicon.
After I tested Superpi. Shorter 1M I had 5100 MHz also, but the screenshot is not saved... So at least one at 5000 MHz.
Longer 32M Superpi at 5000 MHz.
Validation process with all active cores+hyperthreading at 5157MHz
7.2 LN2 cooling
And then it could also go on LN2 cooling.
Here, too, did not save the image at 5700 MHz (or have forgotten), I found at my disk only at 5620 MHz
And finally, what do you gaming that Minecraft at 5720 MHz? 🙂
8. Closing speech
Motherboard Asus Maximus Extreme VIII did not disappoint. And Im more than happy for the same product. The board has an excellent layout, BIOS settings, power circuit, good ongoing support for overclockers and options as M2, U2, OC Panel II and the general accesories only show that you are getting something of a luxury. The only one malady for most mortals is price. But this motherboard is not done for all, but for the highest hardwareand OC enthusiast. For those more normal will make a similar salary Maximus Hero, Gene, Impact, or even cheaper Ranger. But if you pulsing blood hardware passion for liquid nitrogen, then definitely take this board. He would even then Chuck Norris 🙂

Today comparison RAM vs RAM with the same clocks and timings setting. How it change the performance? In test are Kingston Savage DDR4 and GSkill TridentZ memory kits.
HyperX Savage are use Hynix chips and at both side of PCB - its called doublesided
GSkill TridentZ are with Samsung chips and single sided.
For*both DRAMs I was use the same primare and second timings. In basic*it was 3000 MHz and 15-16-16-39-1T (details at screenshots)
I tested it in few benchamrks and games. As usually
applications
win for Hynix DS
win for Samsung SS
win for Samsung chips SS
3x win for Hynix DS
draw in Cinebench
Games:
win for Hynix DS
win for Samsung SS
win for Hynix DS
win for Samsung SS
win for Samsung SD
win for Hynix DS
In most cases won Hynix double sided chips. But the difference is really very small. Its not 100% fair game, because both chip has some advantages in tweaking. So for overclockers its additional story. If you are normal gamer/user, no depens if you take this or these order memory kits. From my perspective, I like more tweaking of Samsung chips more.*

you right, oops 🙂
There is right one 🙂
