Yes, the sample configuration file uses the formula from the Winbond W83697HF datasheet, but some board makers prefer to use inverters rather than reference voltages. This could be the case on the K7VT2. However the old MBM init file I have here has slightly different scaling factors: 3.78 (instead of 3.8) for -12V, and 1.575 (instead of 1.68) for -5V. You may want to try these and see if you get values closer from what the BIOS displays. > > > compute in6 -((6.8/10)+1)*@ , -@/((6.8/10)+1) > > I think a user of the K7VT2 sample configuration should be told that there > is a difference in the negative compute lines between the standard of the > w83697hf chip and its implementation on this board. > > I have added a comment to the sample configuration to explain this. > > > > compute in7 ((6.8/10)+1)*@ , @/((6.8/10)+1) > > > > How did you find / validate the compute formulas ? > > in7 is from the sample configuration for the w83697hf. > > For in6 see my comments above. > > > > set in0_min 1.5 * 0.95 > > > set in0_max 1.65 * 1.05 > > > set in2_min 3.3 * 0.9 > > > set in2_max 3.3 * 1.1 > > > set in3_min 5 * 0.95 > > > set in3_max 5 * 1.05 > > > set in4_min 12 * 0.9 > > > set in4_max 12 * 1.1 > > > > The ATX specification says the positive voltage inputs should be within > > a +/- 5% margin, not 10% as you used for +3.3V and +12V > > Corrected. in4_min was still wrong, I fixed it. > > > ignore fan2 > > > > Does the board have a System Fan header?

OK, thanks for checking. I've lowered fan2_min because it is frequent to have low speed chassis fans. > Thanks for publishing in the wiki. Done, thanks for your contribution. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
