strange output values from W83627HG chip

Hi!

I'm just got new server based on Supermicro X7DVA-E mainboard with
W83627HG chip.

Successfully loaded kernel driver w83627hf (using 2.6.20-rc2 kernel
with lm-sensors 2.10.0) and noticed that BIOS values of sensors
differs from lm-sensors output results. 

These are values from BIOS: 

PECI Agent1: 21 C 
PECI Agent2: 18 C 
System Temperature 24 C 

FAN1: 3708 RPM 
FAN2: 3648 RPM 
FAN3: N/A 
FAN4: 1232 RPM 
FAN5: 1260 RPM 
FAN6: N/A 

Vcore A: 1.228 V 
Vcore B: 1.232 V 
-12V -12.809 V 
P1V5 1.488 V 
+3.3V 3.328 V 
+12V 12.192 V 
5Vsb 5.016 V 
5Vdd 4.848 V 
P_VTT 1.194 V 
V_bat 3.152 V 
And these ones I’m getting from linux tool
“sensors”: 

w83627hf-isa-0290 
Adapter: ISA adapter 
VCore 1: +3.36 V (min = +1.34 V, max = +1.49 V) ALARM 
VCore 2: +3.41 V (min = +1.34 V, max = +1.49 V) ALARM 
+3.3V: +0.91 V (min = +3.14 V, max = +3.47 V) ALARM 
+5V: +5.08 V (min = +4.76 V, max = +5.24 V) 
+12V: +4.50 V (min = +10.82 V, max = +13.19 V) ALARM 
-12V: -6.93 V (min = -13.18 V, max = -10.80 V) ALARM 
-5V: -1.98 V (min = -5.25 V, max = -4.75 V) ALARM 
V5SB: +5.75 V (min = +4.76 V, max = +5.24 V) ALARM 
VBat: +2.14 V (min = +2.40 V, max = +3.60 V) ALARM 
Fan1: 0 RPM (min = 3013 RPM, div = 2) ALARM 
Fan2: 0 RPM (min = 2657 RPM, div = 2) ALARM 
Fan3: 0 RPM (min = 2657 RPM, div = 2) ALARM 
Temp1: +29°C (high = +50°C, hyst = +45°C) sensor =
thermistor 
Temp2: +32.5°C (high = +80°C, hyst = +75°C) sensor =
thermistor 
Temp3: +33.0°C (high = +80°C, hyst = +75°C) sensor =
thermistor 
vid: +1.419 V (VRM Version 11.0)
alarms: 
beep_enable: 
Sound alarm enabled 
Very strange values in almost all sensors (voltages, temperature) and
especially in Fan speeds. I could not get any value except zero. 

Some ideas what I’m doing wrong? 

Thanks in advance!
