PCH Diode (Asus Maximus V Formula)

i might give it another try but i just did a fresh re-install - after having massive problems with ram sticks (1 out of 4 appears to be faulty) so this might take some time because i am hoping that one stick was really the cause of all my problems

that means at the moment i am in no way touching asus ai suite ... which i think was the source for the pch temperature to show up in aida ... because when i uninstalled asus ai suite and disabled all the remaining services the pch reading was gone

and right now i have a clean installation without asus ai suite and have to wait a few days to see if everything runs stable ... then i'll make a backup and give ai suite another try just to see if i can get the pch temperature again and then i'll make that embedded controller dump

hi,

no, i actually mean the "PCH Temperature"

in hwinfo64 it is shown as "Intel PCH"

here's the dump:

as i had problems with one of my 4 8GB ram sticks i reinstalled windows 7 ultimate 64bit english several times and with the last installations i was not able to get the reading of pch or phc diode in aida64 again ... no matter what i tried ... i even installed ai suite because i thought maybe ai suite installs something that aida64 get or will use

now i have a new installation with only the software installed that i really need, so no ai suite experimenting :)

i have hwinfo64 installed and it shows:

Intel PCH

PCH Temperatur 43.0 °C (Current)

and 5 mins ago i installed aida64 extreme edition (trial) and the only thing it shows is PCH Core which is a Voltage and not a Temperature

in Preferences Stability i have all options activated except koolance and dimm support

my mainboard: asus maximus v formula / thunderfx with windows 7 ultimate 64bit english

so ... it would be nice if you could make aida64 show the pch diode temperature :)

I didn't wan't to open new topic for this so I wrote here. In older version of aida64 I didn't have that PCB Diode before and now when I install new aida64 2.80.2300 version I got it and it's 43C all the time even when I open my window, and it's cold outside all temps goes down except PCB Diode, what is that anyway PCB Diode, and why is it always 43C ?

PCH Diode is a temperature diode that is integrated in the motherboard chipset (also known as PCH for modern Intel platforms).  Some motherboards have no such diode connected, and some other motherboards may have the diode improperly implemented.  In the latter case the temperature readout may be stuck at a fixed value.  If that's the case, just ignore the reading ;)

PCH stands for Platform Controller Hub. It's the chipset of your motherboard. It is quite normal that a chipset is running at high temperatures, although for PCHs it may be a bit high indeed. Try to improve the cooling of your system case.
