Summary
Possible causes of why the CPU does not reach the maximum frequency (Turbo frequency).
Description
Issues encountered:
- The processor frequency is lower than the Intel® Turbo Boost frequency listed in the Product Specifications page for the processor.
- Why is my system not reaching the Turbo max frequency? How do I fix it?
Resolution
Processors do not run at their maximum frequency all the time. The processor automatically selects the best frequency depending on the workload demand. If workload demand is high and there are no physical constraints, then the processor may operate at or close to the turbo frequency.
Ensure the following:
- Make sure that your system does not have physical constraints that will prevent the processor from reaching its max turbo frequency. Examples of physical constraints of the processor could be power delivery and thermal solution.
- Make sure your processor thermal cooling solution is appropriate for your system, for self-build systems.
- Make sure that processor power limits (PL1, PL2) are allowing the processor to reach its maximum turbo boost frequency. Contact your system vendor for questions/instructions.
- Make sure your BIOS is up to date and/or reset BIOS to its default.
- Make sure the Turbo option (if available in the BIOS) is not disabled. In general, it should be enabled by default. Consult your motherboard/BIOS manufacturer on how to enable Turbo in the BIOS.
| Note | There are many factors that influence the processor operating frequency, such as the system overheating, choice of appropriate fan heatsink, adequate power supply, and workload. |
