@jmort11​  Are there any replacement hardwares available? If I were you, I would look for another board/psu to replace the old ones, then check if the cpus are still underlocking.

Hello jmort11,

Thank you for posting on the Intel® communities. 

To better assist you with your request, I will need to check some information about your computer.

Please run the following tools and attach the reports generated

1. Intel® System Support Utility (Intel® SSU)

• Intel® SSU Download link
• Open the application and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".
• Click on the menu where it says "Summary" to change to "Detailed View".
• To save your scan, click on "Next", then "Save".

2. Intel® Extreme Tuning Utility (Intel® XTU)

• Intel® Extreme Tuning Utility (Intel® XTU) download link.
• Download the tool, once it is downloaded go ahead and install the software on your computer, the system will ask to be restarted, after that you can run the software.
• When you open the software select Stress Test, check the box ''CPU Stress Test'' you can do it for 5 minutes then take screenshots showing the Max core frequency, CPU utilization, etc (all the screen) and attach them.

3. Questions:

• Is the Intel® Turbo Boost Technology enabled from the BIOS?
• Is the Intel® SpeedStep® Technology enabled from the BIOS?

Hello jmort11,

Thank you for the updates.

I will be waiting for your response once you check the BIOS settings, in the meantime you can try the following steps:

• Load BIOS default settings.
• Check power management on BIOS and make sure you have max performance features enabled some motherboards have some features in order to save power and it can make the components work at low performance.
• Make sure all the power cables are properly connected.
• Once you get into the BIOS if Intel® Turbo Boost Technology is disabled, enable it and if the Intel SpeedStep® Technology is enabled, disable it.
• Check if the Processor power management on the Operating system is in max performance.

Question:

Did the same issue happen on the same motherboard with the 2 processors Intel® Core™ i7-8700K and Intel® Core™ i5-9600K?

Hello  jmort11,

Thank you for your answer.

• Were you able to check the settings on the BIOS?
• Is there a way you can test the processors on a different motherboard to see if you get the same results?

i checked the bios the voltage is as high as it can got to which is CPU core voltage is set to 1.359v and the turbo boost is disabled but i couldn't seem to find the speedstep technology, no i do not have a motherboard to test it on and nobody i know does have spare one.

Get back to me as soon as u can

Thanks,

Hello jmort11,

Thank you for your answer.

Based on screenshots you sent us about the Intel® Extreme Tuning Utility (Intel® XTU) it seems the Intel® Turbo Boost Technology is enabled.

Upon checking your answer the Intel® Turbo Boost Technology is disabled, can you please enable it from the BIOS? 

Can you please run the Intel® Processor Diagnostic Tool?

Intel® Processor Diagnostic Tool Download link

• Once installed, the Intel® PDT starts testing the processor using the default configuration. Two windows might appear to show the test is in progress.
• When the Intel® PDT completes, the testing status will display either a PASS or FAIL.
• You can open or save the test results file by clicking on file > view results file, file, then, save as to any location you specify.
• Please attach the result to the thread.
