Thermal Throttling stuck on

Casper5632 wrote: I recently purchased a Asrock Z97 Formula OC motherboard to put a 4790k on. Upon completely installing the motherboard the Thermal Throttling is stuck in the on position as long as it is enabled in the BIOS. I disabled Thermal Throttling and played a game for an hour with no performance impact or serious temp issues on the mobo or the CPU. The highest temp HWMonitor picked up on any of the Mobo or CPU sensors was 60C in the entire hour of gaming, so I am assuming there is an issue with the thermal throttle function or maybe a switch on the board is causing it. I already updated the BIOS and reset to default settings and it is always thermal throttling if the function is available. Suggestions?

I think I know what you are trying to describe, please jump to the end of this post for the quick solution ***.

The description in the manual of the CPU Thermal Throttling option is this:

Enable CPU internal thermal control mechanisms to keep the CPU from overheating.

CPU Thermal Throttling is a safety feature Intel builds into their processors to protect them from damage. If the processor reaches 100° C (for your i7-4790K), the programmed throttling threshold temperature, it will automatically begin reducing the processor's speed, so its temperature (hopefully) will drop below 100C. If the processor's temperature continues to increase, its speed will be further reduced. If the temperature increases to the programmed catastrophic temperature value, the processor will be automatically turned off by the Thermal Throttling feature.

Disabling Thermal Throttling will prevent the processor's speed from throttling when it exceeds 100° C, but it should still shut off if it reaches the catastrophic temperature.

Your description of what you did when you disabled Thermal Throttling did not explain anything IMO.

What happens when Thermal Throttling is enabled? What is the problem you are having?

*** If your CPU is running at a low speed constantly, the reason is the Slow Mode Switch is set to On from the factory. The Slow Mode Switch is the first switch to the left of the Dr Debug display.
