Detailed information about Motherboard
SIW reads PC systems main health sensors : voltages, temperatures, fans speed.
The program handles the most common sensor chips, like ITE® IT87 series, most Winbond® ICs, and others.
In addition, it can read modern CPUs on-die core thermal sensors, as well has hard drives temperature via S.M.A.R.T, and video card GPU temperature.
Special hardware monitors such as abit® uGuru and Gigabyte® ODIN power supplies serie are supported too.
SIW uses CPUID's System Monitoring Development Kit.
The temp readings in the bios have been tweaked in the bios's code such that they're quite accurate for the particular motherboard model.
Third party hardware monitoring programs like SIW make assumptions about the sensor readings that may not be correct for the particular motherboard model.
Sometimes sensors for something are not connected to the intended inputs on the hardware monitoring chips - the motherboard manufacturer compensates for that, but SIW doesn't.
SIW may show a reading for an input no sensor is connected to - it never changes in that case, and may even be an impossible reading.
SIW helps you find what those unknown PCI devices in Device Manager really are. By checking Device Manager for unknown devices and extracting information from it, this program attempts to figure out what the PCI device is.
Similar with Linux's lspci, but for Windows.
