CPU stops working after some houes

[pzneupa]

I am using Intel(R) Core(TM) i5 -8400CPU @2.80GHZ with six cores for computational software which has capability of parallel processing and uses all cores simultaneously. Initially CPU gets fully utilized with 100% uses and performs pretty well. But when time passes (generally 2-3 hours) the cpu uses suddenly drops and could not proceed with further computation. Is this the issue of long term use of processor at high speed. What should be done to avoid that and continue use CPU for longer period upto 48 hrs at full speed.

Hello @pzneupa

Thank you for posting on the Intel® communities.

In order to check this further, could you please provide the following information?

1- Did the system work as expected before or are you experiencing this behavior since the first day that you have the computer?

2- If this worked fine before at any moment, were there any recent hardware or software changes that might relate to the point when the issue started? (for instance, Windows®, driver, or software updates?)

3- When you said "the CPU uses suddenly drops and could not proceed with further computation", what is the exact behavior? Is the performance slower or (for instance) do the computation results take longer to complete? Is the software crashing or showing any error/warning message? Please provide details.

4- When the processor utilization drops, do you notice any drop in the processor's frequency and or any sign of overheating? Feel free to provide screenshots from Windows® Device Manager > Performance tab showing the behavior.

5- What are the name and the version/build number (if applicable) of the computational software? Also, please provide details of the steps you follow in case we may try to replicate this.

6- Please run the Intel® Processor Diagnostic Tool to verify that both the processor and the GPU (Graphics Processing Unite) are fine.

To save the report, once the test is done, click on "File >> View Results File" and attach the .txt file to your reply.

7- Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system.

• Download the Intel® SSU and save the application on your computer
• Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
• To save your scan, click Next and click Save.
• Once you have saved the file (.txt file), please attach it to your reply.
• To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.
