在今天的帖子中，我们将探讨Windows 10^{(Windows 10)}系统^(System)属性页显示的CPU 频率^{(CPU frequencies)}不匹配问题的原因和可能的解决方法。从系统^(System)属性页面，您可以更改视觉效果、处理器调度、内存使用和虚拟内存。

如果您有一台带有多个Intel处理器的^(Intel)Windows计算机，并且您打开系统^(System)属性页面，在处理器^(Processor)部分下，显示了CPU名称，但列出的两个频率不匹配，那么这篇文章解释了原因。

如果您安装英特尔协作处理器性能控制 (CPPC)^{(Intel Collaborative Processor Performance Control (CPPC))}驱动程序，则可能会发生这种情况，该驱动程序提供额外的电源管理并延长电池寿命。并且安装了Intel CPPC驱动后，系统^(System)属性页面中列出的第二个CPU频率与第一个不匹配。

CPU频率在^(CPU)Windows 10中不匹配

在Control Panel > System页面中，您可能会看到针对您的Processor列出了两个不同的CPU频率。为什么会这样？

根据微软支持知识库^{(Microsoft Support KB)}文章：

The first frequency that is listed for the processor is fixed and part of the name of the processor. The second frequency is normally computed by Windows using P-states or the frequency of the time stamp counter. However, when the Intel CPPC driver is installed, the system uses CPPC to manage the frequency of the processor and not P-states. As a result, Windows uses the time stamp counter frequency to determine processor frequency. 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.

微软^(Microsoft)指出，这是一个表面问题，不会影响Windows管理处理器频率的方式。Windows在任何给定时间点都知道处理器频率，并将相应地对其进行管理。

希望这些信息对您有所帮助。^{(Hope you find this information helpful.)}

Processor frequencies do not match in Windows 10

In today’s post, we will explore the cause and possible resolution to the issue of CPU frequencies shown in Windows 10 System property page do not match. From the System property page, you can change visual effects, processor scheduling, memory usage, and virtual memory.

If you have a Windows computer with multiple Intel processors, and you open the System property page, and under the Processor section, the CPU name is shown but the two frequencies that are listed do not match, then this post explains why.

This can happen if you install the Intel Collaborative Processor Performance Control (CPPC) driver, which provides additional power management and increases battery life. And after the Intel CPPC driver is installed, the second CPU frequency listed in the System properties page does not match the first one.

CPU frequencies do not match in Windows 10

In Control Panel > System page, you may see two different CPU frequencies listed against your Processor. Why does this happen?

According to Microsoft Support KB article:

The first frequency that is listed for the processor is fixed and part of the name of the processor. The second frequency is normally computed by Windows using P-states or the frequency of the time stamp counter. However, when the Intel CPPC driver is installed, the system uses CPPC to manage the frequency of the processor and not P-states. As a result, Windows uses the time stamp counter frequency to determine processor frequency. 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.

Microsoft points out that this is a cosmetic issue and does not affect how Windows manages the processor frequencies. Windows is aware of the processor frequency at any given point in time and will manage it accordingly.
