That would be good news, I could never understand the logic behind the 3.963 or 3.984 scaling factors other Gigabyte boards were using. I have always attributed them to software bugs. OTOH the offset you mention below makes no physical sense either, so it would be a software trick from Gigabyte again. Oh well. BTW, Did you validate your findings with a digital voltmeter? Even if it's not accurate, it can be useful to ensure that +12V has the same value when in the BIOS setup and later on Linux (to make sure you are comparing scaled and unscaled numbers for the same physical value.) > Just some comments before, the fan1 speed is setup for my case, with > the minimum pwm it doesn't go slower.

This file should work Both are OK and strictly equivalent. The (30/10)+1 form is to reflect the physical reality of scaling (a bridge made of a 30 kOhm resistor and a 10 kOhm resistor. > with MA785GMT-UD2H like the other config on internet but I think also > could work with MA785GPM-UD2H as it has a very very similar PCB.

Also, if you could get a 3rd value for +12V in the BIOS, it would help validate your formula. > > # The BIOS won't set any limit for voltages. > # You should set Vcore and Vram to match you setup, mine is: > # - CPU: AMD Athlon II X2 250 (VCore 0.85-1.425) > # - Mem: KHX8500D2/2G (Vram 1.8-2) > > set in0_min 0.85 * 0.95 > set in0_max 1.425 * 1.05 > set in1_min 1.8 * 0.95 > set in1_max 2 * 1.05 These are voltage limits for DDR2... There's something fishy here. Ah, I think I get it. There are two board series, the MA785GM uses DDR2 and the MA785GMT uses DDR3. So if you have DDR2 your board is really a GM, not GMT version. You got it wrong in the header. > set in2_min 3.3 * 0.95 > set in2_max 3.3 * 1.05 > set in3_min 5 * 0.95 > set in3_max 5 * 1.05 > set in4_min 12 * 0.95 > set in4_max 12 * 1.05 > > ### Temperatures > > # The BIOS only shows 2 temperature values, corresponding to Sys and CPU, > # temp3 is usually similar to Sys temp but under heavy load it raises more. > > label temp1 "Sys Temp" > label temp2 "CPU Temp" > label temp3 "NBr Temp" # Guessed > > set temp1_min 10 > set temp1_max 50 > set temp2_min 10 > set temp2_max 60 > set temp3_min 10 > set temp3_max 50 > > ### Fans > > # I only have CPU fan, the other ones have to be tested. > > label fan1 "CPU Fan" > label fan2 "Case Fan" > ignore fan3 > label fan4 "NBr Fan" > > # Adjust for your own fans > set fan1_min 450 > #set fan2_min 1000 > #set fan4_min 1000 All the rest looks good, I'll update the wiki, thanks. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
