OverClock Checking Tool (OCCT) 5.5.4
Free Download for Windows PC

CPU:OCCT

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.

CPU:LINPACK

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.

GPU:3D

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

GPU:Memtest

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.

Power Supply

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.

CPU Temperature Monitoring

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
