WinFix: i7 owners Win7 by default is crippling our CPU's

post #1 of 93
Thread Starter 
By default Windows 7 uses Core parking with our i7 CPU's, This is a power savings feature and it actually decreases performance and isnt needed on Desktops but designed for Laptops.

For example: With a i7 2700K when cruising the net with Firefox/Safari etc. or compressing a file with WinRAR youll notice that only 4 threads are being used not 8. The core parking feature of Windows 7 is crippling our performance.

To get all CPU Threads working all the time we have to Disable Core parking in Windows 7, below is how we do this and unleash the true performance of our i7 CPU's smile.gif


Step 1: Go into Task Manager/Resource Monitor and see if any cores are parked, If so then go to step 2.

Step 2: Run Utility. (this utility uses the "Official" way of disabling core parking, which is the powercfg command)

Download the Disable Core Parking Utility from the URL or attachment below

http://bitsum.com/about_cpu_core_parking.php

parkcontroldist64.zip 947k .zip file


Now you have disabled Core Parking which in my opinion is what it should be like in the first place. smile.gif

Enjoy the "True" Performance of your i7 CPU thumb.gif

Yeah I was shocked when I found out it was doing this, I was wondering why 4 threads were never being used lol

The only way I saw all the threads being used was in IBT and prime95

There's also a free utility to disable/enable core parking if you don't want to go through the hassle of editing stuff in the registry.

Are you sure that the programs are coded to utilize 8 threads? Also do you really need 8 threads to browse the internet, I doubt your CPU is the bottleneck there. Winrar could possibly benefit though.

That is not only for i7 CPU's, it applies to everything that uses HT (Pent 4's, i3's, Xeons), and BD CPU's. I used that on my i3 and worked too.

its not about bottlenecking. Its about telling the OS task scheduler to treat the HT cores as real cores when scheduling them
