[How To] Testing Processors

Processor is one of the most important components of any computer system. The processor is required to operate error-free 100% of the time. If there are any errors, they can cause system instability and crashing. Typically the errors are manifested through a series of BSOD crashes, but may sometimes not appear if the Operating System does not even get a chance to detect a possible hardware failure. This guide will show you how to test your processor to make sure it's trouble-free.

 

 

You can use software that will put the load on the processor causing it to stress and work at its 100% capability. This procedure will often make any errors surface shortly during the test.

 

The best tool for testing the processor is called Prime95. You may download it here:

 

 

The number of threads is typically automatically inserted and should be left at default. Yours may be higher or lower than 4 depending on the processor.

 

When you click OK, the test will begin. If there are any issues with the test, you will see an error come up inside of the program.

 

Another possibility is that the system will simply crash under load.

 

If it does crash, repeat the process, but instead of choosing BLEND test, this time around choose Small FFT's. This test will focus mainly on the processor. If the test crashes again, then you probably have an issue with the CPU and it has to be replaced. If it doesn't crash, this may indicate an issue with the memory as well.

 

Keep in mind that overclocking can have an effect on how this test goes. If you are raising the CPU or Memory clock and/or voltage, you may experience instability. Please remove or lower the overclocking when performing troubleshooting of this caliber.

 

It's also recommended to monitor the CPU temperatures as you continue to stress test your system. You can follow our guide on temperature monitoring to help you along the way.
