I have a core i5 4570. With turbo and speed step enabled the clock speed should change in cpu-z but it doesn't for somr reason. It just stays at one clock speed all the time. I have also checked on other monitors but its the same. Any idea why?
Try changing your power option to Power Saver and see if anything changes. If not even then, go back to Recommended and go to advanced settings for that option and check what is set in the processor section.
