OCCT (stands for "OverClock Checking Tool) is a CPU stability testing program.
Its features :
3 different test types
CPU = no RAM tested, alot of heat generated on the CPU, errors are usually CPU-centered
RAM = Maximum error detection, tests the whole chain CPU-Chipset-Memory
Mix = CPU and RAM alternated
3 tests modes
Auto = 1h long Mix test
Custom (Infinite) = Infinite loop of the test type of your choice
Custom (fixed) = A test of the type of your choice, and of a duration of your choice
Integrated monitoring and System information thanks to CPU-Z and HWmonitor engine
External Monitoring Program support through plugins (Everest, Speedfan, and many more)
Graph output showing temperatures and voltages of your computer
Changelog :
MONITORING
BugFixs : Now OCCT properly detect all 4 cores temperatures on some quad-cores CPU, and OCCT properly detects CPUs in Vista (some were problematic)
OCCT now supports ACPI Sensors and HDD Sensors (SMART)
TRANSLATION
The "default.po" file used for translation is usable again - it was corrupted in the previous release
Changelog 2.0.0 :
TEST
Brand new and more effective tests !
CPU : generating much more heat
RAM : More effective at generating errors
Mix (Former CPU&RAM) : alternating CPU and RAM tests. You'll see peaks in the CPU temperature graph : this is normal !
Auto test is now 1h long
Custom test is now 2h long by default. Don't forget you can change this in the options !
A sound is played if any error is detected
MONITORING
CPU-Z SDK used : OCCT now uses the CPU-Z SDK Engine to get your system information !
Built-in monitoring : OCCT now integrates HWMonitor and will auto-configure itself for temperatures and voltages monitoring
CSMT common monitoring interface : OCCT is now using plugins to control monitoring programs (Speedfan, Everest,...). The details of this interface will be released soon.
INTERFACE
You can now select the custom test type in the main window of OCCT
The ON button now blinks when a test is running (if it is not blinking : error or your computer froze)
Option windows completly revised with new options (mainly related to graphs - see below)
OCCT's version number is now visible on the main window
Many new languages supported (Hebrew, Spanish,...)
GRAPHS
Graphs can now be generated in 2 different sizes - Check the options !
CSV files can be generated, containing the monitoring information of every graph
