...it's a Penryn, so looks like it's unsupported (one year too old). Oh well. Thanks for all replies, very informative nonetheless. -- View this message in context: http://freebsd.1045724.x6.nabble.com/Bogus-turbo-mode-with-Intel-R-Core-TM-2-Duo-CPU-P9700-2-80GHz-tp6147461p6147683.html Sent

Nice! Will give it a shot next time I will have cpuctl module around :) -- View this message in context: http://freebsd.1045724.x6.nabble.com/Bogus-turbo-mode-with-Intel-R-Core-TM-2-Duo-CPU-P9700-2-80GHz-tp6147461p6147681.html Sent from the freebsd-stable mailing list archive at Nabble.com.

I've found that the original technology was called Intel Dynamic Acceleration, though it should be only utilized if not all cores working? I'm ok with overclocking, as you've said, it's not too hot and only 30C when idle, just wanted to know what exactly is going on under the hood (as in

Thanks for reply! If Ive understood you correctly, that means the ACPI  table somehow provides (lists) turbo mode for this CPU even though it does not support it [1]? Is there a way to check its real speed under load? Im guessing no. [1] ark.intel.com ark.intel.com

Re: Bogus turbo mode with Intel(R) Core(TM)2 Duo CPU P9700 (2.80GHz)

the acpi cpu frequency module just exposes the frequency lis given to it by ACPI. If your ACPI table exposes the turbo boost frequency but doesn't implement it on the backend, FreeBSD doesn't know. We just obey what we're told. :) -a On 25 November 2016 at 20:16, Jakub Lach
