Crashes occur when overclocking for roughly three hours.
Hey, guys. I tried to overclock my CPU to 4.6GHz at 1.4V, ran Aida 64 for about four hours and everything worked fine—temperatures stayed around 68°C under load. After that, things got weird; my PC froze and wouldn’t let me restart or shut down, so I had to cut power.
I managed to get stable at 4.5Ghz with 1.3V, but problems started when I increased the frequency by 100Mhz.
I have an i7 6700k, H55 Corsair water cooler, MSI GTX 970, Asrock Extreme 4 Z170, 16GB OCPC RAM at 2133 MHz, and an Aerocool integrator 850 watt PSU (80 PLUS BRONZE).
That's possible. It's also possible you may need to fine tune the overclock a bit more, each cpu is different. You might try a variation of baseclock and multiplier overclocking, you may need to raise or lower your uncore/ring multiplier. You may also need to use an offset.
Here's a decent guide that may be able to help, this is just one of several out there.

If the cpu truly has hit its limit then it's possible it's not a great overclocker. Unfortunately overclocking isn't guaranteed, though 4.5ghz isn't totally a loss either. If comparing to stock speeds the cpu only turbo boosts to 4.2ghz and may not even maintain that if all 4 cores are active.
It's possible you've hit the stable CPU limit. A crash indicates instability, and resetting it back to normal usually works. Around 4.5ghz appears to be the maximum. Overclocking requires careful temperature management, keeping voltages within specs, and ensuring overall system stability.
Testing tools like ASUS ROG RealBench can assess CPU, RAM, GPU performance in different setups. Even if a system passes all tests, crashes during regular use suggest another factor—such as software or drivers—might be causing the issue. This seems unlikely unless it's only problematic with certain games or programs.

Unlikely here unless it's only unstable at 4.6Ghz after extended use. So, are you missing something important?

4.5Ghz is a very respectable over clock don't get me wrong and obviously won't bottleneck any GPU I throw at it for years to come but it's just a shame that sometimes there can be a fault in the fabrication process of building a CPU to limit its potential but if I can't get passed 4.5Ghz so be it
I'll give that guide a go and I'll let you know
Edit: The guide has worked well for me, thank you for helping me out!
