Hello Cy, Wednesday, September 5, 2018, 3:12:34 AM, you wrote: > Are you running powers? powerd? yes. With "adaptive" strategy" > Do you use c-states? Oops. My fault. I've forgot to set cx_lowest to C3 on all cores. BTW, these four settings in rc.conf(5) performance_cx_lowest performance_cpu_freq economy_cx_lowest economy_cpu_freq do NOTHING. They are not used ANYWHERE but rc.conf and rc.conf.5! > What happens if you boot in (instead of switch to) turbo mode? Sorry? I could only turn Turbo mode on/off in BIOS before boot. BTW, "Turbo mode enabled + dev.cpu.X.cx_lowset=C3 + powerd" works, but gives only 1601 Mhz, not 2240MHz max: TURBO ON: dev.cpu.0.freq_levels: 1601/2000 1600/2000 1520/1900 1440/1800 1360/1700 1280/1600 1200/1500 1120/1400 1040/1300 960/1200 880/1100 800/1000 720/900 640/800 560/700 480/600 420/525 360/450 300/375 240/300 180/225 120/150 60/75 TURBO OFF: dev.cpu.0.freq_levels: 1600/2000 1520/1900 1440/1800 1360/1700 1280/1600 1200/1500 1120/1400 1040/1300 960/1200 880/1100 800/1000 720/900 640/800 560/700 480/600 420/525 360/450 300/375 240/300 180/225 120/150 60/75 But I could live with that :-) -- Best regards, Lev mailto:lev@FreeBSD.org
