Then the usual accusation saying this waste power for server when it is idleing most the time. Then when you are doing light work, your system would just run with lower Pstate, and enter Turbo during high load. If one has a concern on this, one could just use the power scheme "Portable/Laptop", like I did, even with a desktop system. If the given CPU does not support Turbo boost, it would be under its default max frequency with this setting anyway.

The CPU would be under Turbo Boost most of the time. The said CPU(s) would run at Pstate-0 most of the time (except when entering enhanced Cstate which it would reduce to lower Pstate before idle). Take the Windows XP for example, if an user choose the power scheme "Home/Office Desk". It is again depends on the user's choice of power policy. I have personally seen a Linux variance kernel debug check if this is not fulfilled.Ī side note on this is that there are also people claim that CPU running at higher frequence unnecessarily. The sixth requirement is not quite obvious. Turbo boost is guarded by thermal and power headroom, enabling (deeper) Cstate would help CPU running at higher frequency because headroom are likely available. Thus the system (BIOS and OS) must support ACPI and turn those options on.

The Pstate entries, P1 should be corresponding to the chip default frequency.

The said OS must turn on its power management features, for both Pstates and Cstates.

EIST and Turbo Boost BIOS option must be turned on.

Well, I'll just list down some simple short rules for any OS to run Turbo boost here and of course, this is from the AM FU DZone :)

and some wishes that AMD's implementation would 'fix' that bug. hence one need to turn of Turbo boost in running benchmarks. Just seen some funny accusation that Intel's Turbo Boost is broken, not working in Linux.
