Low CPU Frequency, maybe Thermal Throttling error?

Hello,

So I'm having an issue with my CPU stuck at a 0.8GHz Frequency. I tried multiple ways of fixing this but as I searched nothing seemed to work.

Disabling C States and setting my power for performance has done nothing. I even overclocked my i7 to 44x. Even tried to use Throttlestop for a temporary fix but I can't seem to find a working version.

My frame rates are still terrible, usually staying at 27 to 30 FPS but only when high activity is going on.

I think it might be a faulty sensor and maybe I can get confirmation on this? This is the first time I've dealt with this but my CPU stays usually at a solid 30C to 50C temperature even while stressing it.

However, Intel will still Thermal Throttle at random times.

My CPU stays at a usual x8 Multiplier but will rarely work to the x44 OC setting.

Even ran a Cinebench run and I'll usually get scores like these:

But once or twice I scored 900+ but usually when the computer is first booted up.

Any advice on how to fix this or comfirmation that will help me decide on getting a replacement MB will be greatly appreciated.

PC Specs Below:


Cooler:
Noctua NH-L12 120mm & 92mm SSO Bearing PWM Fans CPU Cooler

CPU:
Intel Core i7-6700K

Motherboard:
MSI Gaming Z170A GAMING M7 LGA 1151 Intel

PSU:
Rosewill Photon-850, PHOTON Series 850W Full Modular Power Supply

GPU:
NVIDIA GeForce GTX 1080

Thank you for your time.
Also, I apologize if I made grammar mistakes. I stayed up all night trying to fix this.

Here it shows cooling is close to failure in YELLOW.

Have a look at that picture. The package temperature is only 35°C. The cooler is definitely not failing.

Intel XTU does not correctly report what is going on so I would suggest not to use it.

Download the latest version of ThrottleStop from TechPowerUp and disable BD PROCHOT. A sensor has gone bad on the motherboard and it is sending random throttling signals directly to the CPU using the BD PROCHOT signal path. When you disable the BD PROCHOT signal path, this will block these outside signals getting to your CPU. No more throttling. The only time your CPU will throttle is if it actually reaches 100°C. This is a separate signal called PROCHOT and it is not affected when...

The NH-L12 is a low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first rate performance in its class, it is not suitable for overclocking and should be used with care on CPUs with more than 95W TDP (Thermal Design Power).

Intel Core i7-6700K has a TDP of 95 watts. (Thermal Design Power)

Other factors are your case cooling and choice and application of thermal compound. It looks like you have:
1) poor case cooling depending on case airflow
2) less airflow from use of low noise adapter fan
3) some thermal compounds are better than others, but they all need to be applied correctly.

The Intel Extreme Tuning Utility can be used as strictly as a monitor and be run while running benchmarks.

Reset BIOS to optimal defaults.
I believe that what your CPU may be encountering is transient temperature spikes, especially since you use auto voltage, which sets unsafe voltages.

When overclocking manually set voltages.

Transient temperature spikes happen when the heat output is so great CPU reaches 100 degrees C instantly and hence quickly switches to throttle to 0.8 GHz.

Set a manual voltage, less than 1.4V, and do not auto volts.

Tried switching out the cooler for a better liquid cooler, still got 0.8 GHz.
Tried lowering the voltage, no luck.
Best option now was to go ahead and stop the thermal throttling. Must be a fault in the MB. Guess I'll need a new motherboard one day.
