Yes off course.  The remaining 0.22 GB is reserved for windows.  The software will not use all the 4 GB.  So you can install the software

Just try the below step to change the default graphics card

How to set a default graphics cardStep OneOpen the Nvidia Control Panel. You can do this by right-clicking on the desktop or you can find the option within the notification area of the Taskbar.

Step Two

Select Manage 3D Settings under 3D Settings.

Step Three

Click on the Program Settings tab and select the program you want to choose a graphics card for from the drop down list.

Step Four

Now select the 'preferred graphics processor' in the drop down list (you can see what the automatic option is listed as global setting). If you want to use the dedicated graphics card, select High-performance Nvidia processor.

Note: For ATI/AMD graphics cards the process varies. Open the control center in the same way as above. You may need to open graphics then PowerPlay and set plugged in and/or battery to maximize performance. You can also try going to graphics then 3D and move the slider to performance. Your computer may also have a switchable graphics tab where you can change the settings for individual programs.
