Hello.
I have a laptop with an intel 4500U CPU. 1.8GHz stock clock speed and 2.7 turbo speed.
When i stress my CPU is starting working at much lower than 2.7GHz. This starts happening at about 70 degrees (C). Then it works stably in 65 degrees (aproximately) and with a low clock. The max temperature for this CPU is 105.
Is it normal to throttle in this temp? Can i change this? When i really need the cpu power i cant have it.
If i turn off intel speed step what will happen? Is dangerous? If my CPU overheat will my OS throttle it with the speed step off?
(i have power plan at max performance and battery off laptop)
UPDATE
I turned off the speed step and then I had a steady clock speed of 0.8 GHz, so it was a fail test.
Then I tried to keep track of my CPU behavior and i noticed two kinds of throattling.
1. In the stress test i had a thing called power limit throattle. My cpu default turbo boost power is 15W. For short periods it can work with even higher power supply. While temperature goes over 65 degrees power limit was activating and keeping temp at 65 on average. Clock speed 2.3-2.7 GHz.
2. When gaming temperature could go even higher. Up to 75 degrees. Then heat throattle was also activating. While gaming my CPU was always working at stock speed (1.8 Ghz) and 65-75 temperature.
So to conclude my CPU seems to work fine. But it is very strange for me to face low fps in some games that a month ago i could play easily with 50% more fps. I cant understand the reason behind that.
Also i noticed one more strange behaviour.
In the past if i had in a game (like csgo) 50-100++ fps i was frame limiting my game and i could play with stable 60-65 fps.
Now when i dont frame limit i still have 45-100++ fps. But when i do i have a lot less (40-65).
In both scenarios my clock speed is 1.8Ghz
