This driver enables users to monitor the clock generator chips on the motherboard. Not a traditional hwmon chip in the temp/volt/fan sense, I agree, but it's been useful for me when I want to confirm that clock rates are what they're supposed to be. It's also helpful to know whether or not spread spectrum is enabled if the CPU clock is a few tenths of a % below what I think it should be. (Yes you can over/underclock by writing to this chip, but someone else can do that; I don't recommend it.) --D _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
