Summary
Steps to identify and troubleshoot low performance indicators on unlocked 12th generation Intel® processors
Description
CPU frequency is not constant and drops a few minutes after boot.
Resolution
Follow the troubleshooting steps below:
- Use the benchmark in the latest version of the Intel® XTU.
- Make sure all other applications are closed.
- Make sure the BIOS is updated to the latest version
- Set the BIOS to default then go to BIOS settings to ensure PL1 and PL2 values are set properly, as these values may impact/limit the cores' turbo frequency.
- Perform a clean install of Windows 11*, as this operating system can use the Intel® Thread Director to optimize the use of 12th generation P and E cores for maximum performance.
- Use a high-performance cooling solution (very efficient air cooling models / All In One with at least a 2-fan radiator or a custom water loop).
- Use a high-quality motherboard with a VRM capable of providing the power needed by your Intel processor.
- Ensure your power supply meets the required power consumption of the PC while using an Intel® 12th generation processor.
- Depending on the rest of your PC parts (especially the video card) you may need to use an up to 1000W high-quality power supply
