Hi, I'm wondering if there is an easy way to monitor the voltage of an Intel Core CPU with Linux. Windows tools like cpu-z report CPU information such as speed and multiplicator, but voltage and even temperature as well. I don't think those Windows tools have a complete set of hardware monitoring drivers built-in, and there is already the coretemp driver to monitor the temperature of an Intel Core CPU. Do you know any way to monitor the voltage of my CPU? BTW: I have a Toshiba Tecra A9 notebook on which lm_sensors can't identify the hardware monitoring chips: Some chips are also accessible through the ISA I/O ports. We have to write to arbitrary I/O ports to probe them. This is usually safe though. Yes, you do have ISA I/O ports even if you do not have any ISA slots! Do you want to scan the ISA I/O ports? (YES/no): Probing for `National Semiconductor LM78' at 0x290... No Probing for `National Semiconductor LM78-J' at 0x290... No Probing for `National Semiconductor LM79' at 0x290... No Probing for `Winbond W83781D' at 0x290... No Probing for `Winbond W83782D' at 0x290... No Probing for `Silicon Integrated Systems SIS5595'... No Probing for `VIA VT82C686 Integrated Sensors'... No Probing for `VIA VT8231 Integrated Sensors'... No Probing for `IPMI BMC KCS' at 0xca0... No Probing for `IPMI BMC SMIC' at 0xca8... No Some Super I/O chips may also contain sensors. We have to write to standard I/O ports to probe them. This is usually safe. Do you want to scan for Super I/O sensors? (YES/no): Probing for Super-I/O at 0x2e/0x2f Trying family `National Semiconductor'... No Trying family `SMSC'... Yes Found unknown non-standard chip with ID 0x7a Probing for Super-I/O at 0x4e/0x4f Trying family `National Semiconductor'... No Trying family `SMSC'... Yes Found unknown chip with ID 0x0b00 Some CPUs or memory controllers may also contain embedded sensors. Do you want to scan for them? (YES/no): AMD K8 thermal sensors... No Intel Core family thermal sensor... Success! (driver `coretemp') Intel AMB FB-DIMM thermal sensor... No coretemp works just fine, but I have no way of monitoring anything else which is quite unsatisfying to me... Maybe you guys can help me monitoring at least vcore! best regards, Peter
