Problems with non-K Overclocking on a i7 6700

[_Trasher]

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?
