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 wrote: > Hello, > > Since I'm running this CPU, I've noticed there is additional > field in supported frequency (under heavy load)- > > dev.cpu.0.cx_supported: C1/1/1 C2/2/1 C3/3/57 > dev.cpu.0.freq_levels: 2801/35000 2800/35000 2450/30625 2133/23888 > 1866/20902 1600/15000 1400/13125 1200/11250 1000/9375 800/12000 700/10500 > 600/9000 500/7500 400/6000 300/4500 200/3000 100/1500 > dev.cpu.0.freq: 2801 > dev.cpu.0.temperature: 67,0C > > as far as I know, the +1 MHz mode is a turbo boost factory > overclock, however this CPU does not support it.
