Here's my sensors command output: root at Belladonna:/etc# sensors acpitz-virtual-0 Adapter: Virtual device temp1: +21.8?C (crit = +96.8?C) k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +64.0?C Core1 Temp: +63.0?C k8temp-pci-00cb Adapter: PCI adapter Core0 Temp: +52.0?C Core1 Temp: +49.0?C w83627thf-isa-0290 Adapter: ISA adapter VCore: +0.98 V (min = +0.70 V, max = +1.87 V) +12V: +4.13 V (min = +3.10 V, max = +0.97 V) ALARM +3.3V: +1.89 V (min = +1.54 V, max = +2.30 V) +5V: +4.83 V (min = +0.96 V, max = +6.51 V) -12V: -10.30 V (min = -13.43 V, max = -8.33 V) V5SB: +4.97 V (min = +3.92 V, max = +1.80 V) ALARM VBat: +2.82 V (min = +0.00 V, max = +0.13 V) ALARM fan1: 0 RPM (min = 168750 RPM, div = 2) ALARM CPU Fan: 0 RPM (min = -1 RPM, div = 2) ALARM fan3: 0 RPM (min = 10384 RPM, div = 2) ALARM M/B Temp: +61.0?C (high = +4.0?C, hyst = +2.0?C) ALARM sensor = thermistor CPU Temp: +57.0?C (high = +80.0?C, hyst = +75.0?C) sensor = thermistor temp3: +43.5?C (high = +80.0?C, hyst = +75.0?C) sensor = thermistor beep_enable:enabled The only information there that's nearly correct is the values for +5V and V5SB. Maybe the Vbat is ok. My CPU's are both running 100% usage, and temps are more like 50C at idle, 70C at full usage (measured in Windows). AMD spec for Vcore for Opteron 285 is 1.30-1.35V. Bios says 1.29/1.34V. CPU frequency scaling is @2.6GHZ. My system periodically freezes, and that's believable if Vcore is really 0.98V. It does however, run fine at 2.2GHZ @Vcore 0.94V. My MOBO is MSI K8N Master2-far; dual CPUs are Opteron 285 @2.6Mhz. My sensor chip is reported as w83627thf, but I'm doubtful. My PSU is PC Power & Cooling Silencer 750, rated 750W, peak 825W, single rail +12V @60A. It can deliver the juice. My watt meter says the system is consuming ~300W, so I'm not even close to drawing down the PSU. I'm on Kubuntu 8.10. Any help?
