Hi, I have just finished building a computer at uni. It has two dual core Opterons 275 on an MSI K8N-DL. It is very hot in my town at the moment and I would like to monitor temperature etc. I *think* that sensors-detect is running all fine, the output I get from `sensors` is: <quote> w83627thf-isa-0290 Adapter: ISA adapter VCore: +1.02 V (min = +0.94 V, max = +0.96 V) +12V: +4.13 V (min = +10.82 V, max = +13.19 V) +3.3V: +1.92 V (min = +3.14 V, max = +3.47 V) +5V: +5.04 V (min = +4.75 V, max = +5.25 V) -12V: -14.91 V (min = -10.80 V, max = -13.18 V) V5SB: +5.08 V (min = +4.76 V, max = +5.24 V) VBat: +2.93 V (min = +2.40 V, max = +3.60 V) fan1: 5578 RPM (min = 9375 RPM, div = 2) CPU Fan: 5769 RPM (min = -1 RPM, div = 2) fan3: 0 RPM (min = 112500 RPM, div = 2) M/B Temp: +47 C (high = +5 C, hyst = +0 C) sensor = thermistor CPU Temp: +42.0 C (high = +80 C, hyst = +75 C) sensor = thermistor temp3: +39.0 C (high = +80 C, hyst = +75 C) sensor = thermistor vid: +0.275 V (VRM Version 9.0) alarms: beep_enable: Sound alarm disabled eeprom-i2c-0-53 Adapter: SMBus nForce2 adapter at f800 Memory type: DDR SDRAM DIMM Memory size (MB): 1024 eeprom-i2c-0-52 Adapter: SMBus nForce2 adapter at f800 Memory type: DDR SDRAM DIMM Memory size (MB): 1024 eeprom-i2c-0-51 Adapter: SMBus nForce2 adapter at f800 Memory type: DDR SDRAM DIMM Memory size (MB): 1024 eeprom-i2c-0-50 Adapter: SMBus nForce2 adapter at f800 Memory type: DDR SDRAM DIMM Memory size (MB): 1024 <\quote> This suggest that the rail which ought to have 3.3V, provides only 1.9! Does anyone have any information about whether this is a real problem/artifact? What's my next step? Thanks for any advice and for bearing with my ignorance! James
