Very odd. The processor is an Athlon 64 X2 4850e. Being one of the newer energy efficient 45 watt models I suppose there might be a difference in the temperature sensor. It might also be an issue with the motherboard (Foxconn FC-6150M2MA-KRS2H). After I got the motherboard I needed to upgrade the BIOS in an attempt to fix an unrelated problem. Prior to the update even the BIOS reported silly high temperatures and I remember FreeBSD reporting a constant 40C but I don't remember whether this was from sysctl, k8temp or mbmon. I don't overclock the system so after satisfying myself that it doesn't have any tendency to overheat I no longer have much need to monitor the CPU temperature so I think the way my system reports temperatures will just remain as one of life's little mysteries. -- Mike Clarke ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

But for some of us this command does not work. It never reports anything but 40 C on my Athlon 64 X2 6000+. sysutils/k8temp, however, reports 20 C /28 C. -- Tore ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

It works for me, I ran it and sysctl hw.acpi.thermal.tz0.temperature every 2 seconds in a while loop and cpu temperatures follow cpu activity closely and change in 1deg steps between about 25deg and 42deg. When I rebooted and checked temperature in the BIOS it was pretty much the same as what k8temp was saying just previously. hw.acpi.thermal.tz0.temperature is fixed on 40deg even with high cpu activity. Maybe your processor is not supported?

According to http://www.alcpu.com/CoreTemp/supportlist.html it includes AMD processors but when I load coretemp.ko sysctl still can't see dev.cpu.?.temperature.

According to the man page the coretemp driver only provides support for the on-die digital thermal sensor present in Intel Core and newer CPUs, suggesting that it wouldn't work for AMD CPUs. But I get sensible looking results for my Athlon 64 X2 4850e with the following command: sysctl hw.acpi.thermal.tz0.temperature > According to > > http://www.alcpu.com/CoreTemp/supportlist.html > > it includes AMD processors but when I load coretemp.ko sysctl still > can't see dev.cpu.?.temperature. > > Is this even the same coretemp as the website talks about windows a > lot?
