Hi,
thanks all for all your detailed answers. Very useful. I got it
regarding the voltage.
Here is the patch I did for it87c. As you said, I simply searched for
IT8718 and add IT8720 to do the same.
I looked into my BIOS and here is what I have:
vCore = 1,33
3,3 = 3,4
5 = 5,02
12 = 12,09
Since I have identified the chipset from my mother board, can you let
me know wich pin are the "in" so I can mesure the resistors and
provide the values? You might found that (the pin#) in the datasheet I
hope.
Regarding pwm4 and pwm5, I'm not really sure how to do so, and I seen
that some fans info was missing. So I will try to figure how to use it
since I have 3 fans and only 2 are displayed.
fan1: 3013 RPM (min = 0 RPM, div = 2)
fan2: 0 RPM (min = 0 RPM, div = 2)
fan3: 5973 RPM (min = 0 RPM, div = 2)
Last point, temperatures are slightly different from it8720 and k8temp.
temp1: +41.0 ?C (low = -1.0 ?C, high = +127.0 ?C) sensor = transistor
temp2: +34.0 ?C (low = -1.0 ?C, high = -3.0 ?C) sensor = transistor
temp3: +22.0 ?C (low = -5.0 ?C, high = +127.0 ?C) sensor = transistor
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +43.0 ?C
Core1 Temp: +37.0 ?C
Has it87 only the motherboard temp? In that case, why there is 3? I
will receive a 4-core this afternoon so I will be able to do some
other tests.
I will keep you posted if I'm able to do something for pwm4 and pwm5.
Regard,
Jean-Marc
