Disable Processor core

Hey guys, i have Intel i7 3610QM and i would like to know how i can disable a processore cores, (and would that lead to lower temperatur/energy usage)? Also i know that my processor is quad-core based but why does device maneger and msconfig indicate 8 cores?

Thanks for the help

 

8 cores are indicated because your processor has HyperThreading: this means that the OS sees 8 virtual ("logical") cores, although there are 4 physical cores. There is no effective way to disable processor cores that would result in actual power savings, so I would just recommend you to use a power-saving energy plan, which will cap the core clock frequencies and keep power usage down.

 

If you are really looking to "super-mile" the thing, you can look into forcing core-parking. Depending on what you plan to do during this energy saving mode, you might find that limiting your CPU performance to bare minimum might be unacceptable, but you can start at the minimum and work your way up. Core-parking is not exposed in Windows 7, so you have to tweak a few settings in the registry to reveal them. See this thead:

E.g. I can lock my core i7-2860QM @ 5W max. (but there's no way I can tolerate the hit in performance for any usage I do)

 

Edit: Nevermind, it's already been posted. Read above OP.

 

if Hmm... Thanks for the answers! I really appreciate it all! I found a way to disable the cores through msconfig, and i have been wondering if disabling the core will that result lower temp since the core is basicly doing nothing at that point.

 

Given the most of the time your cores are already going to be idle to start with, this will not result in significant power savings whatsoever. The core isn't disabled...it is just unused...which is no different than leaving it enabled and idle.
