CPU Temperature on a AM3+ Sockel #312

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
hey there, 

having troubble with reading the cpu-temperature on my am3+ fx6100 on a 
Gigabyte 990fxa-UD7
and sorry for my bad english, btw. ;)

it shows something between 12 and 20 °C

EasyTune6 shows me something between 24 and 33 °C, what is a possible value.
Running a Gamer-System, selfemade with this specifies:

AMD FX "Bulldozer" 6100 (AM3+)
Gigabyte 990FxA-UD7 Mainboard
CPU-Fan: Deepcool IceWing 5 Pro (max 150watts) 

i tried all possible (Beta-)Bios-Versions, but it doesen`t took effects. 
running F8a, yet, what is the newest one.

The following is a copy of a comment from "wavingecko" posted wrongly on Issue 
311:

jepp, just uploaded an report with open HardwareControl

i just renamed it by googeling the temperatues for the mainboard.
So the AMD-FX-Temp. is wrong

Mainboard Temps should be

Temp1: System
Temp2: power (if supported)
Temp3: CPU

I am getting about 9 degrees of Idle Temp / About 25 degrees of load temp on an 
AMD FX 6100 Chip which can't be right. 

Using HW Monitor 0.4 Beta

As far as I know this is an issue with the AMD CPUs. AMD has documented for 
quite some time that the "core temperature" accessible through registers is not 
really on a degree Celsius scale, but on a virtual one. Nevertheless, on older 
CPUs this has given good enough results. See also the attached part of the 
"BIOS and Kernel Developer’s Guide (BKDG) for AMD Family 15h Models 00h-0Fh 
Processors".

The offset isn't really known, it might not even be constant per CPU type. So 
currently I do not see any way to fix this issue. See also the Core Temp forum.

http://www.alcpu.com/forums/viewtopic.php?f=62&t=2231

If the latest version of Core Temp gives different results than the Open 
Hardware Monitor, I might look into it once more.

The readings for the CPU temperature obtained from the mainboard should be the 
same as in other software (but still different from the core sensors results).

If you see any indication for what might be wrong or how to fix (or obtain info 
for a fix), please let me know.
