Don't know if this is a bug or a feature but the Windows 8 Task Manager always shows frequency higher than CPU-Z.
When I do CPU intensive task, it shows 5.10 Ghz frequency which is obviously wrong as my i5-3550 has maximum frequency limit of 4.10 Ghz.
Anyone noticed this? Clean re-install nor updating BIOS helped.
the newer intel cores have "Turbo Boost". Which will underclock your CPU automagically during low loads. During more CPU intensive tasks it will bring it up to speed. It's possible that when CPUz is launched it doesn't have much load and as such you see a lower speed, whereas I am assuming Windows 8 can take that into account and show the maximum, as well as the current.
