What is OCCT used for?
Table of Contents
OCCT is the most popular all-in-one stability check & stress test tool available. It generates heavy loads on your components while checking for errors, and will detect stability issues faster than anything else. OCCT embeds HwInfo’s monitoring engine to get precise readings and diagnose issues faster.
Is OCCT a good stress test?
OCCT offers a fairly challenging CPU stress test, which often gets overlooked. It might not generate the massive amounts of heat we measure under Prime95 with AVX, but it’s still a great choice for long stability tests.
How do I check if my CPU is overclocked?

Open the Task Manager by either right clicking on the Task Bar and then selecting Task Manager or by pressing CTRL + ALT + DELETE and then selecting Task Manager. Select the Performance Tab and check the “Speed” provided. If this is higher than the turbo frequency of your CPU then its overclocked.
Is OCCT better than Prime95?
Prime 95 vs OOCT The choice of OCCT or Prime95 for stress testing is largely down to preference, but there are differences. OCCT works by varying the load very fast, which puts more stress on the VRMs to keep up, triggering VCore undershoot and overshoot as the loads goes up and down.

What are OCCT errors?
This means your clock speed is not stable, and could result in crashing. Either turn up the voltage, or turn down the clock speed.
Is it good to overclock?
In short, you don’t need overclocking, but if you’re running applications that benefit from it, there’s no reason to leave the extra performance on the table. You shouldn’t go too far, though. Extreme overclocking can shorten your component’s lifespan and decrease system stability. It may void your warranty, too.
Is RealBench enough?
An offset of -2 or -3 (200 or 300 MHz) is usually sufficient. Asus RealBench runs a realistic AVX workload typically within +/- a few % of TDP, and is an excellent utility for testing overall system stability, whether you’re overclocked or not.
How do I check my graphics card memory?
In the Display Settings box, select Advanced Display Settings and then choose the Display Adapter properties option. On the Adapter tab in the box, you should see the brand of the graphics card and its memory amount listed.
How do I test my CPU for errors?
You can use a utility like Prime95 to stress test your CPU. Such a utility will fore your computer’s CPU to perform calculations without allowing it to rest, working it hard and generating heat. If your CPU is becoming too hot, you’ll start to see errors or system crashes.
Can Prime95 damage my PC?
It will not damage your computer – just monitor your temperatures the entire time, and if anything gets too high, you’ll want to stop the test and look into better cooling solutions. If the computer shuts off during it, the power supply is likely poor quality and in need of replacement.
