Windows 11 Processor Clock Speed Error

Question

I'm attempting to install Windows 11, however every time I try - I'm getting a processor clock speed error: "The processor clock speed needs to be 1 Ghz or faster." I'm currently running a 3.1 Ghz Intel Core i5-9600, 16GB RAM, NVME SSD, TPM and Secure Boot enabled. This processor is listed as a compatible CPU in the Windows 11 System Requirements. Any ideas?

Answer 1

I was able to give it a try, however it still did not work. Any further ideas?

Answer 2

No overclocking, no modifications. It's a stock PC, less than a year old.

PC Health Check gives me all green with the exception of processor clock speed. It tells me the clock speed is .8 GHz - however gives me a green check with the actual processor being 3.1 GHz.

Hi.

You should check minimum processor speed in power options.

Open Run dialog box ( Winkey + R ). Type in control.

When classic Control Panel window opens, click Power Options. Select Balanced ( Recommended ), if not already selected, and then click Change Power Plan Settings.

Then click Change advanced power settings.

When advanced power settings window opens, change minimum and maximum cpu setting to 100%.

Try the upgrade again.

If upgrade is successful, then you can revert the processor settings to original, previous values.

Hope this helps.

Are you overclocking? maybe that is causing a misreading of the CPU frequency.

Please, run the PC Health Check app to make sure your device is fully compliant.
