This is a cosmetic issue and does not affect how Windows manages the processor frequencies. On systems with Intel-based processors that support configurable thermal design power (TDP), this may result in the second frequency listed being different from the first. As a result, Windows uses the time stamp counter frequency to determine processor frequency. However, when the Intel CPPC driver is installed, the system uses CPPC to manage the frequency of the processor and not P-states. The second frequency is normally computed by Windows using P-states or the frequency of the time stamp counter. The first frequency that is listed for the processor is fixed and part of the name of the processor. You then install the Intel Collaborative Processor Performance Control (CPPC) driver, which provides additional power management and increases battery life.Īfter the Intel CPPC driver is installed, the second CPU frequency listed in the System properties page does not match the first one.Under the Processor section, the CPU name is shown and two identical frequencies are listed.You have a Windows computer with multiple Intel processors.This article provides a solution to an issue where the CPU name is shown and two identical frequencies don't match on the System property page.Īpplies to: Windows 10, version 2004, Windows 10, version 1903, Windows 10, version 1909, Windows 7 Service Pack 1, Windows Server 2016, Windows Server 2019, Windows Server 2012 R2 Original KB number: 2878342 Symptoms
