Portable OCCT Retail 11.0.21 (x64) Multilingual



OCCT (OverClock Checking Tool) Portable is a software tool that provides advanced capabilities for testing the stability and performance of computer systems. It was developed by Ocbase, a French software development company, and is available for free download.

One of the key features of OCCT Portable is its ability to stress test the CPU, GPU, and RAM components of a computer system. This allows users to identify any instability or performance issues with their hardware, which can be especially useful for those who have overclocked their system. OCCT provides real-time monitoring of temperature, voltage, and clock speed, enabling users to identify any potential problems before they cause damage to their system.

OCCT Portable also includes a number of other useful tools, such as a system information utility that provides detailed information about the user’s computer hardware and software configuration. There is also a benchmarking tool that allows users to compare the performance of their system against others, thereby identifying areas where improvements can be made.

Another key feature of OCCT Portable is its customizable settings. Users can choose between different types of tests, such as CPU or GPU tests, and can adjust the duration and intensity of the test to suit their needs. This allows users to fine-tune their system to achieve optimal performance while minimizing the risk of damage to their hardware.

OCCT is also highly user-friendly. The interface is intuitive and easy to navigate, making it accessible even to those with limited technical knowledge. The software is compatible with a wide range of operating systems, including Windows, Linux, and macOS.

Overall, OCCT is an essential tool for anyone looking to optimize the performance of their computer system. Its advanced capabilities, customizable settings, and user-friendly interface make it an ideal choice for both novice and experienced users alike. Whether you’re a gamer, professional video editor, or just looking to improve the performance of your everyday computer use, OCCT has the tools you need to achieve your goals.

OCCT Portable is the most popular CPU/GPU/Power Supply testing tool available. OCCT is great at generating heavy loads on your components, and aims at detecting hardware errors or overclocking issues faster than anything else. A monitoring engine is also embedded, to ease diagnostic and see how your computer reacts under heavy load using graphs.

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 Portable 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.


OCCT’s own CPU test. Small data set is great at pushing your CPU to its limits, and Large data set is the best at finding errors quickly

The famous Linpack test, known for pushing Intel CPUs to their limits. Not as great on AMD CPUs though, and less likely to pick up errors than OCCT

OCCT’s version of the furry donut, which includes a error detection mode for finding rendering errors automatically

Exclusive OpenCL-based Memtest for testing your graphic card’s memory ! Runs on any GPU (Intel, AMD, Nvidia) with OpenCL support. It is great at finding faulty bits, less at finding overclocking-induced errors

Combines CPU:OCCT and GPU:3D tests to stress your power supply and motherboard. This test is the most power-hungry included in OCCT. Useful to identify power-starved components !

OCCT will monitor your computer and present you real-time graphs showing you temperatures, voltages, fan speed, frequencies, component usage, and power consumption during your tests.

Built-in protection for your computer
Worried about frying your components ? Turn the maximum temperature threshold in OCCT’s options ! Should a component reach this critical temperature during a test, OCCT will stop itself immediately.

Test report
At the end of a test, you will be able to save a full graphical report of what happened during the test, for diagnostic purposes
