The Intel Skylake i7-6700K Overclocking Performance Mini-Test to 4.8 GHz

WinRAR 5.0.1: link
Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30 second 720p videos.
3D Particle Movement
3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores.
FastStone Image Viewer 4.9
FastStone is the program I use to perform quick or bulk actions on images, such as resizing, adjusting for color and cropping. In our test we take a series of 170 images in various sizes and formats and convert them all into 640x480 .gif files, maintaining the aspect ratio. FastStone does not use multithreading for this test, and results are given in seconds.
Synthetic – 7-Zip 9.2: link
As an open source compression tool, 7-Zip is a popular tool for making sets of files easier to handle and transfer. The software offers up its own benchmark, to which we report the result.
Conclusions on Office Benchmarks
Similar to the professional tests, the gains here are in-line with what we would expect with +200 MHz overclocks.

If HB exposes errors which the other programs do not find, it is a stress test. Just a different one. It's not about the highest power draw & temperature, but about a code path which apparently takes a bit longer to complete than others and hence can't be pushed to such high frequencies.Dr_Orgo - Sunday, August 30, 2015 - link
The conditionally stable overclocking results were pretty interesting. When I overclocked my GTX 970, I primarily used Unigine Heaven to stress test. Got to 1500 MHz stable with voltage maxed in Precision X. Used it in a number of games with zero crashing even with sustained 100% usage, seemed completely stable. Running the unit preloader (loads all units/annimations) in Starcraft 2 would make the game crash every time. Dropping the overclock to 1460 MHz made it stable. I'm not sure what specifically makes that unit preloader less overclock friendly.LemmingOverlord - Monday, August 31, 2015 - link
I think the premise behind the Discrete Graphics tests are incorrect. If you max out the settings you are capping the performance of the system by the graphics card. If you lower the settings just a bit, you'll definitely see how the CPU influences overall game performance. I know this is a mini-test, but these discrete tests prove absolutely nothing on how the overclock impacted the game performance.Either lower the detail on these tests, or test with a game that is non-GPU Intensive. Civ V is an excellent benchmark for CPU tests, because it really is CPU-intensive...

In the past couple of months, we see alot of BSOD and freez and what not from media encoding softwares.Some of our friends mentioned (while they were testing), that this maybea a global XMP issue.
Same resaults regarding handbrake were showing on z77 z68.
Just to comment

Not impressed, my 4690k does 4.8ghz with a $29 Hyper Evo....InstinctXIV - Friday, November 20, 2015 - link
I would love to see your 4690K do this http://imgur.com/U6ZZ1Ll (It is my PC)gravy1958 - Monday, October 19, 2015 - link
I have a 6700k with an asus maximus ranger viii MB and an hours gaming produces regular clock_watchdog_timeout errors if I use the overclocking... and frequent boot fails with the random overclocking failed press F1 to enter setup 8^(gravy1958 - Monday, October 19, 2015 - link
should add it is set at 4.6Ghz and all advice points to the voltage being too low.jonainpdx - Thursday, May 5, 2016 - link
It's pretty obvious that overclocking a new, state of the art CPU is nothing more than a waste of money for a gamer.
