That's an off-topic question, as it has nothing to do with lm-sensors, but I'll reply still... > lm-sensors 3.3.3 > decode-dimms in the i2c-tools 3.1.0-3 and even I tried rev.6068 > kernel 2.6.32.20 and even I tried 3.4.2 > motherboard - Supermicro X8DTG > > modprobe i2c-i801 > modprobe i2c-dev > modprobe i2c-core > modprobe eeprom > 'i2cdetect 3' give table something like this > > 0 1 2 3 4 5 6 7 8 9 a b c d e f > 00: -- -- -- -- -- -- -- -- -- -- -- -- -- > 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- > 20: 20 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- > 30: -- -- -- -- -- -- -- -- UU -- UU -- UU -- -- -- > 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- > 50: 50 -- 52 -- 54 -- -- -- -- -- -- -- -- -- -- -- > 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- > 70: -- -- -- -- -- -- -- -- Most multi-CPU boards use SMBus multiplexing with memory for each CPU being on a separate bus segment. This is explained here: https://i2c.wiki.kernel.org/index.php/I2C_bus_multiplexing Support for Asus Z8 series boards was added in kernel 3.7, you'd probably need something similar for your board. Unfortunately this can't be auto-detected, so you have to get the multiplexing information from the vendor. You need to know what multiplexing chip is used, and for GPIO-controlled multiplexing chips, which motherboard chips' GPIO pins are used. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
