I'm not sure if Precision Boost is working on my processor. Core Temp 1.14 tells me its running at about 3637MHz where as CPUID says 4041MHz and CPU-Z tells me 4092MHz. Which is telling the truth?
Go to this pc/computer in the system propertys and Look at your CPU and see the speed
Or install minecraft play and press F3 and search for the CPU în the right side )
