Oh, thanks! I'm guessing there's something different about mine though, because 114 - 27 is 87, and under Windows is reports 67C when it's completely maxed out. Maybe with its 4 units (32 cores) the offset is -54C (2*27) instead? -- Rebecca > On Mon, Nov 5, 2018 at 3:14 PM Rebecca Cran via freebsd-hackers > > wrote: > > On Monday, 5 November 2018 14:23:22 MST Zaphod Beeblebrox wrote: > > > kldloading "amdtemp.ko" reports an idle temp of 55C or so and heavy > > > compiling (make world -j32) reports temperatures as high as 95C ... upto > > > and including some instability and/or crash or rebooting. > > > > I have a new Threadripper 2990WX in an ASUS motherboard - and mine just > > reports ridiculous values: > > > > % sysctl dev.amdtemp | grep sensor > > dev.amdtemp.3.core0.sensor0: 112.6C > > dev.amdtemp.3.sensor_offset: 0 > > dev.amdtemp.2.core0.sensor0: 113.5C > > dev.amdtemp.2.sensor_offset: 0 > > dev.amdtemp.1.core0.sensor0: 111.7C > > dev.amdtemp.1.sensor_offset: 0 > > dev.amdtemp.0.core0.sensor0: 114.5C > > dev.amdtemp.0.sensor_offset: 0 > > > > -- > > Rebecca > > > > > > _______________________________________________ > > freebsd-hackers@freebsd.org mailing list > > https://lists.freebsd.org/mailman/listinfo/freebsd-hackers > > To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org"
