Yes, I realized it after sending, missing Reply-To-Header. So I resent it to the list, too. > Yeah, 1.250V for VRM8.5 means that all the VID inputs read 0. I don't > think they are connected.

I do have an voltmeter, but I am not going to measure, since it really am afraid of killing the cpu of a short. > 2) There are scaling resistors on the Vcore input pin of the vt1211. > Assuming Vcore should be 1.4V, you can add the following compute line: > > compute in2 @ * (1 + 1.47 / 10), @ / (1 + 1.47 / 10) Your computing line is working: vt1211-isa-6000 Adapter: ISA adapter +3.3V: +3.30 V (min = +3.14 V, max = +3.47 V) +2.5V: +2.38 V (min = +2.38 V, max = +2.63 V) ALARM VCore: +1.40 V (min = +1.35 V, max = +1.44 V) +5V: +4.66 V (min = +4.51 V, max = +5.49 V) +12V: +11.49 V (min = +10.77 V, max = +13.21 V) +3.3V: +3.28 V (min = +3.13 V, max = +3.46 V) Case Fan: 0 RPM (min = 3006 RPM, div = 2) CPU Fan: 0 RPM (min = 3006 RPM, div = 2) CPU Temp: +45.4 ?C (high = +85 ?C, hyst = +79 ?C) Int Temp: +61.0 ?C (high = +65 ?C, hyst = +60 ?C) vid: +1.250 V (VRM Version 8.5) Now other voltages are computed correctly. Well, the values still might need some adjustments, since I can't believe, that 2.5V is 2.38 and 12V is 11.49. What do you think about it?
