Task Manager reporting wrong CPU frequency

i5-3550 is Non-K edition. It cannot be overclocked.

You can overclock any CPU, the K-series CPUs just have an unlocked multiplier and better overclockability than non K-series CPUs.

Mine also does the same.

Gotta be something with Turbo Core. My C2Q never goes about 2.67 (currently 2.61 doing a movie compression.) Reported the same in CPU-Z.

While typing this, fired up my older Dell laptop and it's running a core2duo and I can report the same. CPU-Z and Windows 8 Task manager report the same speed.

I have all power management turned off, turbo boost, speedstep etc.

Atleast yours is going few Mhz above rated speed, Mine goes almost 1 Ghz above in task manager. :laugh:

The funny thing is, my CPU is clocked at 3.2Ghz, so all figures are incorrect.

More than likely, the Windows CPU read doesn't read the chip speed in real-time, as CPU-Z does. Instead it must take a limited number of parameters and run them through an algorithm to guess the current operating speed of the chip. The real question is why would they need to do this? CPU-Z does it in real-time so why not do the same? It is possible that this data is being fed in real-time in places like Performance Monitor and they are hoping to reduce load on the CPU by not polling constantly?

Either way, it isn't correct and is a bug the should be fixed.

I'm not sure what the other users can't seem to understand in this thread. Talks about TurboBoost and SpeedStep are pointless when CPU-Z is always reporting the current CPU operating speed, including TurboBoost dynamic overclocking and SpeedStep dynamic underclocking.Sometimes I wonder if people just post for the sake of posting...

    • Sure, that must be why it was revealed at the Sony showcase... the game was announced 5 years ago and the visuals are far from poor, what the hell are you smoking, plus the Switch 2 is pretty much on par with an Xbox Series S. It would be absolutely insane for a dev to build a game "with the Switch 2 in mind" when it's coming to all platforms where the majority of sales will happen.

    • Microsoft makes it easier to find PC specs in Windows 11 Settings by Taras Buria Windows 11 has already received several improvements that make it easier to learn about your computer's specifications. Recently, Microsoft released Spec Cards for the System > About section, which provide basic information about the PC's main components, such as processor, memory, storage, graphics card, and video memory. Now, the Settings app is getting a new way to find your device info. Microsoft wants to display basic device information right on the Home page of the Settings app. The latest preview builds from the Dev and Beta Channels introduced a new "Your device info" card for the Settings' Home page. It displays specs like processor name and speed, graphics card and the amount of video memory, storage, and RAM. The card also has a link to the "About" section, where you will find more information about your computer, its Windows edition, product ID, and the recently introduced FAQ section that answers common hardware-related questions. The "Your device info" card joins the existing cards on the Settings app's home page. While the section offers useful information like quick access to Bluetooth devices, Wi-Fi, personalization, and recommended settings, users received it with mixed reactions, as many considered it another way for Microsoft to promote its services and subscriptions like Microsoft 365, OneDrive, and Game Pass (seriously, who thinks about Game Pass when opening Settings?). Now, the Settings' Home page is a bit more useful, as it saves you a few clicks when checking your computer's specs. If you want to test the new "Your device info" card, update your PC to build 26200.5622 or newer (Dev Channel). Just keep in mind that Microsoft is rolling it out gradually, and it requires signing in with a Microsoft Account in the United States. Other changes in build 26200.5622 include a new Settings section for Quick Machine Recovery, widget improvements, more app recommendations in the "Open with" dialog, and more. Check out the full release notes here.
