TweakTown's Ultimate Windows SSD Performance Installation Guide (Page 8)

Advanced Power Settings

These settings will assure that your CPU is giving all it is capable of by preventing throttling and core parking. This also boosts SSD performance. Depending on your setup, these registry settings can deliver as much as a ten percent increase in storage performance. Some will see an increase, and some may not; it really depends on how your particular BIOS is setup.

For your convenience, we have these registry settings available for download. You can download them by clicking HERE.

By merging these registry entries, we get advanced power settings that were previously unavailable. After you have downloaded the registry entries, you need to merge them into your registry. Begin by right clicking on a registry file.


Select "Merge," and hit "enter."


A warning will pop-up; select "yes."


A confirmation notice that the values have been successfully entered into the registry will be issued. Repeat the procedure with the remaining five registry entries.

Now when we browse to advanced power settings, and expand "Processor power management"...


... we have a bunch of power settings that were previously unavailable. Go down the list, and set everything to 100 percent:


Keep "Processor performance decrease policy" set at "Single." Hit "apply" and "exit". Note: Windows 7 users may need to do a restart before all the policies are listed.

To insure core parking is completely disabled, we can manually turn it off. Open an administrator command prompt and paste this line: "powercfg -setacvalueindex scheme_current sub_processor 0cc5b647-c1df-4637-891a-dec35c318583 100" (without the quote marks of course).


Hit "enter," and do a restart. Now you have assurance that power is being delivered consistently, and that Windows cannot park cores, or throttle your CPU.
