ThrottleStop is a performance adjustment tool for Core 2 / Core i CPUs. It monitor for and correct the 3 main types of CPU throttling that are being used on many laptop computers.
The left side of ThrottleStop contains a variety of options which can be used to bypass CPU throttling and on the right side is a Monitoring panel that shows you the current state of each thread on your CPU.
Right click on ThrottleStop to bring up a couple of new menu options. Not only can the FID (multiplier) be adjusted as high as you like, you can also adjust the VID higher. Hopefully this is going to open up a few doors for users with Extreme CPUs.
Some laptops are using clock modulation and multiplier reductions to lower the performance and power consumption of your computer. This is done deliberately to either allow your computer to run cooler or to allow your laptop to operate with a power adapter that is not sufficient to fully power your laptop and recharge its battery at the same time.
Once you adjust the FID or VID higher than the default setting, this setting will remain in the CPU until you reboot whether ThrottleStop is running or not. To reset both of these settings, there is a right mouse menu option in ThrottleStop called Reset CPU FID/VID which will take your CPU back to its default settings.
If you have an Extreme CPU like an ES that is not properly recognized as an Extreme CPU by ThrottleStop (ie. no new right menu options to unlock your CPU), you can try adding Extreme=1 to the ThrottleStop.ini configuration file. This trick will do absolutely nothing and might cause problems if you do not have an Extreme CPU.
A Core 2 Extreme CPU should have these two new options available. When using ThrottleStop, it is strongly recommended to monitor power consumption at the wall with a Kill-a-Watt meter or similar device and make sure that you dont exceed the power capabilities of your power adapter. Use of ThrottleStop to bypass these throttling schemes is at your own risk and can result in permanent damage to your power adapter or computer or both which may not be covered by your warranty.
