[TwinTech 8800GT 512Mb HeatPipe Edition] Core temperature reports 0.

Unwinder do you have a clue why RT and SpeedFan shows same temperatures both GPU and PCB but GPU-Z 0.1.6 show same PCB temperature and ~8°C lower on GPU?

 

well, it might be a bit lat, but here is the info off my inno3d 8800 gts 512:

Reg 20008 : c00836d0
Reg 20400 : 00000000​

rivatuner reports a core temp of 52C (built-in dataprovider selected as datasource)

my bios can be found here:

another question comes up reading your post:

do i get this correctly: nvidia does not even use the thermal diode for temp measurements. instead the external sensor in the adt7473 is used. there is just the offset added to the reading of the external sensor and nvidia assumes this is an approximation of core temperature.
so when i select the built-in data provider in rivatuner, is rivatuner just blamed by the bios and gets the external sensors temp + offset reported back to display this as temperature?
thus finally all datasources in rt (built-in, and the two atd7473) are reading from the very same sensor differing only in the offset which is added for the built-in sensor by the bios while the adt7473 sensors are readings without the offset.

 

may be gpu-z is reading from the external sensor directly instead of using the value supplied supplied by the bios.

 

thanks, that was how i understood your post and exactly what i expected ...

 

thanks for clarification - its nice to get my observations confirmed as i already experimented with the various sensors ...

 

Core thermal compensation : 8°C
Correct.

Correct again.

Thanks alot Unwinder. :thumbup:

 

My Asus EN8800GT report this:



Have a solution to read the temperature with Rivatuner?
Thank's

 

OK, I launch your request in our forums. For now Palit 8600GT Sonic+.



I hope I'll come with other results.

 

Another one, if you need it. Gainward 8600GT SilentFX.



LE: Two more.
Gainward 8600GT GS GLH



And another Palit 8600GT Sonic+

GPU 50°C

Ok guys...

A bit of a good news for everyone who has NVIDIA G92 based video card -- mainly 8800 GT 512 MB models which do not have the reference cooling solution and lack ADT7473 chip.

Until Unwinder releases RivaTuner 2.07 and an updated NVThermalDiode plugin, you can download, install and use G92 plugin I wrote from my website downloads section -- www.levicki.net.

Be sure to read the disclaimer though.

 

Thanks ... but how can i select thet plugin to be loaded as default ? i mean i installed it and got a g92.dll but i can not select it in rivatuner ! or i hate to rename it ?

PS : i got it .. it works now !

 

G92 plugin installation instructions

A short guide for those who are not sure how to install and enable the plugin:

1. After downloading, unpack G92.zip archive and you will get G92.rtu file. Double-click on it and you will get the following screen:



2. Read the description carefully and then click the OK button if you agree with the terms of use. Plugin will then be installed.

3. Start RivaTuner and click on Target Adapter -> Customize... -> Hardware Monitoring icon, you will get the following screen:



4. Click on the Setup button. You will get the following screen:



5. Click on Plugins button. You will get the following screen:



6. Make sure that there is a checkmark next to the G92.dll and exit that screen by clicking on OK button. You will get back to this screen:



7. Make sure that there is a checkmark next to Core temperature and that the row is highlighted and then click on Setup button below. You will get the following screen:



8. From the Data provider drop-down list select G92.dll:0 and click on OK button. Click OK again and you should now see the temperature graph showing value other than zero.

 

Waouh ! Nice one. It works for me. And thanks for the guide !

I'll be able to uninstall gamerOSD and SmartDoctor (what a crap !).

I suppose it's impossible but can this value be accessible with SpeedFan application ? I could maybe use it if I were linking my GPU fan to motherboard connector...
