Have you tried to rise it via > sysctl? Oops, I forgot usage of cx_lowest. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - # sysctl hw.acpi.cpu.cx_lowest=C2 hw.acpi.cpu.cx_lowest: C1 -> C2 # sysctl -a | grep cx hw.acpi.cpu.cx_lowest: C2 dev.cpu.0.cx_supported: C1/3 C2/245 dev.cpu.0.cx_lowest: C2 dev.cpu.0.cx_usage: 19.34% 80.65% last 49us dev.cpu.1.cx_supported: C1/3 C2/245 dev.cpu.1.cx_lowest: C2 dev.cpu.1.cx_usage: 15.28% 84.71% last 922us dev.cpu.2.cx_supported: C1/3 C2/245 dev.cpu.2.cx_lowest: C2 dev.cpu.2.cx_usage: 77.90% 22.09% last 6034us dev.cpu.3.cx_supported: C1/3 C2/245 dev.cpu.3.cx_lowest: C2 dev.cpu.3.cx_usage: 80.28% 19.71% last 398us - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - And I can get CPU cooling ~50C(about 45C). Before sysctl cx_lowest=C2, I got 50C~! Thank you. -- Norikatsu Shigemura <nork_at_FreeBSD.org>Received on Sun Sep 12 2010 - 07:39:26 UTC
