Turbo Boost overclocking too much?

[KirbysHammer]

I have an Intel i7 5500U processor. The turbo boost is said to raise the clock speed up to only 3Ghz. However, according to CPUID HWMonitor, It overclocked up to 3147Mhz. Alongside that, the CPU temps reached 102C or 215F. Is this too much? Only core #0 reached 102C, but both cores reached 3.147GHz. Do I need to be worried? Edit: The chip is rated at 15W and it reached 19.59W, and 1.170V. This is all turbo boost, no fiddling of my own. Edit2: Clock speeds have hit 3.25Ghz on one core now. Temps consistently near 100 while gaming as well, depending on the game.

turbo boost should use more power but it should not get so hot when doing it.

But why is it doing that? I know 102C is way too hot. (max temp is 105C) Shouldn't the cpu start throttling?

I'm not so worried about the CPU, but the parts around the CPU. I don't want to burn my laptop to a crisp.

The maximum safe operating temperature for a 5500U is 105°C.

When a CPU core reaches this temperature, it will start to thermal throttle and slow down. It will slow down just enough so the CPU core temperature does not exceed the thermal throttling temperature. 102°C is definitely high but it is still perfectly safe for this CPU. If this temperature was not safe, Intel would have set the thermal throttling temperature lower but they didn't. Using better thermal paste and improving air flow can help with problems like this.

The maximum multiplier when a single core is active is 30 and the BCLK speed is usually about 99.77 MHz so it is unlikely your CPU exceeded 3 GHz. Try a different monitoring program. Run a log file in ThrottleStop and go and play a game and then when you are finished gaming, exit ThrottleStop and you will have an accurate record of your CPU's multiplier.

Almost forgot. Intel gave individual manufacturers the ability to lower the thermal throttling temperature. This CPU feature is called TJ Max offset. Any manufacturer that is worried that 105°C is going to be too hot for some sub-standard component they are using near the CPU does not have to worry about failure. They can use an offset of up to 15°C to reduce the throttling temperature down to 90°C instead of 105°C. If your CPU is going up to 102°C then that means your laptop manufacturer is also comfortable with that temperature, just as Intel is comfortable with 105°C. No worries.

Thanks for the response. Now that I think of it, the CPU has throttled in the past (A bit) While I was running my second display, a few times both my game and the display (which was running a movie slowed down. I doubt it would be GPU throttling, because my GPU never goes above 71C (Nividia Geforce 840M). Lots of people would say that my computer sucks but it can do a lot more than many desktop fanboys think. I can run two displays with a moderate game on one display @1080x1920 and a movie on the other @1280x1080
Doing numerous benchmarks, my CPU scores significantly higher than others of the exact same model and my other components score above average for their model too. I must have gotten lucky XD. Keep in mind this is only a midrange laptop. You can do a lot with laptops. (Btw, I'm glad to hear the good news, I was worried that I would have to disable turbo boost to prevent my computer from self destructing).
