In depth

A closer look at OCCT

Computer performance is very important for every user, especially those who are working with applications that require important system resources to work properly. In order to enhance it, you can use an overclocking utility, such as OCCT (OverClock Checking Tool).This software is designed to help you monitor system hardware components and allow you to overclock them. It provides testing tools for the CPU (benchmark OCCT and LINPACK tests), the graphics card and the power supply.The interface is intuitive and comprises two panels, one that includes the 'Monitoring' section and the other that displays the available tests.In its main window, OCCT displays detailed information regarding your hardware devices, such as the CPU and the motherboard. Also, there is a table where you can view the current and the overclocked CPU and bus frequencies.The CPU and the memory usage are constantly monitored and the values are displayed in a dynamic graph. By default, the program uses HWMonitor to generate them, but it also offers support from third party monitoring software, such as AIDA64, provided that you have them installed in your PC.Whichever test you decide to choose, overclocking can easily be turned on or stopped anytime you want. Before starting, the user has the possibility to select the test type (infinite or automatic), configure its duration and idle periods, as well as other parameters, depending on the selected hardware device.For instance, the LINPACK test allows you to choose the memory percentage, while choosing the GPU test lets you customize the resolution and the FPS limit.Once the selected test is started, you can immediately view the effects on your CPU and memory usage graph, as well as the new values for the CPU frequency.Although it does not offer a wide range of options, OCCT proves to be a handy tool for enhancing the overall system performance.
