Question Problems with non-K Overclocking on a i7 6700

Hello guys!

Today I found this guide from Der8auer (Link) where he explained how to overclock an locked (non-k) CPU.

So I downgraded by BIOS, installed the required BIOS for the overclock and everything worked perfectly normal.

The next thing I wanted to do was applying a overclock to get a total of 4.5 GHZ with a voltage of 1.325v.

After I rebooted into my installation of windows 10 I first checked the CPU temperatures with HWinfo32. Till now there have been no problems, so I started Prime95 and tested the stability for about two hours.

Everything worked perfectly fine but after I closed Prime95 I got an bsod (Clock_Watchdog_Timeout). So I tried to give my CPU a bit more voltage (1.335v, 1.34v, 1.345v, 1.35v) and everytime after the stresstest ended the system crashed.

So I tried to go with 4.4GHZ, but even that crashed after the stresstest.

Here are my BIOS settings:

SpeedStep: disabled
CPU C-states: disabled
CPU-Loadline Calibration: 5 (but I also tried it with 7 with the same result)
Ai Overclock Tuner: XMP
Turbo Boost: disabled
Core Ratio: 34
BCLK: 133 (34 * 133 = 4522)
CPU Core/Cache Current Limit Max.: 255.50
CPU Core/Cache Voltage: Manual Mode
CPU Core Voltage Override: 1.325

The problem also happens when I quickly open different applications, etc.

There is also something else that is very strange: I can't set "Boot Performance Mode to Turbo Performance" because the option doesn't exist in the BIOS.

My specs:
CPU: Intel Core i7 6700 (non-K)
Mainboard: Z170 Pro Gaming (with the required BIOS for the non-k overclock)
Cooler: Kraken x61 (AiO)
RAM: 16GB DDR4 currently at 2133MHZ (max. 3000MHZ) Vengance Corsair

Can anyone help me?
