Question I'm trying to access the Winbond 83627DHG-P IO chip on the motherboard X8SIL. We want to use the LMsensor. Do you have the offset codes for the smbus? Answer Bus Type = ISAIO/SMBus One W83627DHG-P Windbond W83627DHG-P, Slave Address=0x2d (0x5a in 8-Bit format) OR IndexReg=A15, DataReg=A16 ============================================================= Fan1 Fan Speed, Bank 0, Offset 0x29 RPM = 1350000/8/Data Fan2 Fan Speed, Bank 5, Offset 0x53 RPM = 1350000/8/Data Fan3 Fan Speed, Bank 0, Offset 0x28 RPM = 1350000/8/Data Fan4 Fan Speed, Bank 0, Offset 0x3f RPM = 1350000/8/Data Fan5 Fan Speed, Bank 0, Offset 0x2a RPM = 1350000/8/Data CPU Voltage, Bank 0, Offset 0x20 Voltage = Data* 0.008 -12V Voltage, Bank 0, Offset 0x26 Voltage = ((Data*0.008-2.048)/(10./242.))+2.048 +12V Voltage, Bank 0, Offset 0x21 Voltage = Data* 0.008/ (10./66.2) AVCC Voltage, Bank 0, Offset 0x22 Voltage = Data* 0.016 3.3Vcc Voltage, Bank 0, Offset 0x23 Voltage = Data* 0.016 DIMM Voltage, Bank 0, Offset 0x24 Voltage = Data* 0.008 +5V Voltage, Bank 0, Offset 0x25 Voltage = Data* 0.008/ (10./40.) +3.3VSb Voltage, Bank 5, Offset 0x50 Voltage = Data* 0.016 VBAT Voltage, Bank 5, Offset 0x51 Voltage = Data* 0.016 CPU Temperature, Bank 1, Offset 0x50 Temperature = Data System Temperature, Bank 2, Offset 0x50 Temperature = Data Chassis Intrusion, Bank 0, Offset 0x42, BitMask 0x10 1 = Bad, 0 = Good (Clear Bit: Bank 0, Offset 0x46, BitMask 0x80) Power Supply Failure, GP23(From W83627DHG-P) 1 = Good, 0 = Bad Was this FAQ helpful?
