Cpu Speed .

[Ultron-Evolution]

Hello , And To Make It Short I Have An Intel Core i7 2.10 Ghz (Laptop) , Believe Me When I Change My Power Plan To "Balanced" My CPU Goes Over 3.0 Ghz It Doesn't Go Below 2.50 GHz You Have To Believe Its A Laptop And HP Doesn't Allow OverClocking , My Pc Max Speed Is 2.10 Ghz And I Never OverClocked It , Its Happening Since I Changed The Setting On The Power Plan Called "CPU Maximum And Minimum Frequency" I Changed It To 100% And Since Then What The Heck ? It Just Directly Goes To 2.90 And Over To 3.00 Ghz When I Change My Plan To Balanced , Well I Decreased The Frequency To 80 % And Now It Stays At 1.40 Ghz Out Of 2.10 But If Frequency Is Set To 100% In Power Plan Settings It Just Goes To 3.00 Ghz , Despite My Laptop Max Core Speed Is 2.10 . , And I Am Really Worried And I Want To Know Why The Hell It Goes Over Its Max Speed Even Its Not OverClocked ...

Will Be Really Thankful If I Can Recieve Some Info .

its probably the turbo speed

This is called Turbo boost. Intel feature. When your computer does some intensive task which requires less than 4 cores, then your CPU turns off cores and increases the speed of other cores. So what happens is: you do a task which requires 1 core, the other 3 cores go to sleep and this core has its clock speed increased. So that is normal.

here is an article from Intel on what Turbo boost is : http://www.intel.com/content/www/us/en/architecture-and-technology/turbo-boost/turbo-boost-technology.html

I agree that this is normal but there are usually 2 stages of boost. The first being if all four cores are needed the speed will increase to the predetermined speed, as long as there is thermal headroom, and the second is the fastest speed and this is when only one core is in use or the app uses a single thread. Added to this is the normal power saving features that both AMD and Intel implemented that drops the core frequency when the load on the CPU is such that the full CPU speed is unnecessary, this is known as C states.
