Win7 mouse makes you unexpectedly perfect overclocking

In some large games, the performance of the mouse is very high, not only has a high DPI, but also has a very high refresh rate, but it may be a bit difficult for a normal mouse. It doesn't matter, let's take you to experience the perfect overclocking of the ordinary mouse under the win7 system.

Tips: The two most important indicators of the mouse: DPI and refresh rate. DPI is the number of dots per inch, which is the number of points the mouse moves on the screen for every inch of movement of the mouse. The higher the DPI, the more accurate the positioning. The refresh frequency mainly refers to the refresh frequency of the mouse interface. Currently, the refresh frequency of the USB interface is 125HZ, which cannot meet the data transmission requirements of the high DPI mouse.

The DPI of ordinary mouse is mostly between 400-800. This can't be changed, so what we have to do is to increase the refresh rate of the mouse. We can first test the mouse refresh with mouseterate. Rate, the average mouse value will be lower than 125HZ, so it is necessary to carry out overclocking.

Step 1: First find the usbport.sys file under WindowsSystem32drivers in the partition where the system is located, and then copy it to any directory backup to avoid restoration when problems occur.

Tips: Overclocking method is only valid for USB mouse.

Step 2: Right click on usbport.sys, select Properties, then select Security - Advanced, in "Owner ” Set Click Edit to change the file authorization to Administrator, then click “change permission" in the "Permissions" setting, and check the permissions that can be inherited from the object's parent>, then the Administrator Give full control.

Step 3: Right click on usbport.sys, select Open as Open with UltraEdit, click on "Search”, find “3C 08 73 09 C6 83” this string, then put this string Change to "B0 01 73 09 52 8A", after the modification, overwrite the modified file with the original usbport.sys file, restart the computer.

Step 4: Run the mouserate software again, you can see that the refresh rate has become around 360HZ.

After the above operation, you open the game and try your mouse. Does it feel particularly flexible? This mouse performance change can be said to those who use ordinary mouse. A great welfare, you are interested in learning and operating together.
