intel turbo boost technology download 2.7

I'm currently doing a video conversion and the CPU is really cranking away.

It will do 3.7 GHz with 1 core, 3.6 GHz with 2 and 3.5 GHz when 3 or 4 cores are running, On the other hand if the current task is more demanding, the clock speed can increase up to 1000 MHz over the nominal speed depending on the number of cores in use. If my computer is idling and just a few background tasks are running, the clock speed can drop to 1.7 to 2.2 GHz and the power used by the CPU is in the single digits, ~5-7 Watts. Apparently the 2.7 GHz rating is simply a nominal rating and has little to do what is actually happening at any given time. Using Intel Power Gadget I can monitor the clock speed and the power usage. On my particular processor, a 4 core i7 3820QM, the clock speed is listed as 2.7 GHz. Provided you stick to Intel's design guidelines for software and hardware (heat sinks!), I cannot imagine why you would ever want turbo-boost disabled. (I could well be wrong about this and would appreciate feedback if I am.) Given this, a system that keeps itself in turbo-boost mode, despite dangerously high CPU temperatures, sounds like it was written by someone who's incompetent. This really puzzled me, so I went a-googling and found this page, which describes a turbo-boosted Microsoft/Intel system that overheated when running some game.Īll Intel i5 and i7 processors have hardware sensors, that (when used properly) warn the BIOS or EFI when the CPU is overheating. If minimising power consumption is a primary concern (say, for laptops or in server farms) why would you buy a more expensive, turbo-boostable CPU, and then disable turbo-boosting, when you could buy a cheaper, lower-speed CPU, without the turbo-boosting ability, in the first place? Surely the more interesting question is why you would ever want to disable turbo-boost! Why are you wanting to use turbo boost? ' Mleep: 'On non-apple products you would changes these setting in the bios.
