Hi, I've got a very strange effect with the sensor for the
GPU temperature. Using the recent EVEREST Ultimate
I see four temperature symbols in the taskbar tray:
- HDD
- CPU
- GPU
- GPU neighborhood
Within the first refeshment cycle they all show normal.
However from the second refeshment cycle on (i.e. after
5 seconds) GPU and GPU neighborhood show a Zero.
The same happens in the EVEREST main window under
-> Computer -> Sensors. In the first cycle I see all four
temperatures, from the second cycle on the GPU related
entries vanish and never reappear.
What might be the reason for this rather strange behaviour?
It didn't use to happen. The only thing I changed is the
graphics driver, which I updated to a never version.
Could the graphics driver cause such an effect?
Since I have two identical notebooks and they both show
this odd behavior I do not think that it is a hardware
problem (sensor).
Should I provide more information? Which?

1) Please let us know which version of EVEREST are you running, and what video adapter(s) do you have in your system.

2) Copy-paste the full results of the Computer / Sensor page of EVEREST into this topic. It would be best if you could do that before the GPU temperature vanishes.

3) Let me know the old and new video driver version. Changing driver can cause such weird issues on nVIDIA video cards, since on most nVIDIA video adapters EVEREST measures temperatures via a ForceWare driver interface.


Thanks,

1) Everest Ultimate edition 5.30.1900
NVIDIA GeForce FX Go5700

3) New driver: nv4_mini.sys 6.14.11.7580
nv4_disp.dll 6.14.11.7580
nv4api.dll 6.14.11.7580
nv4cod.dll 1, 3, 0, 5
nv4codins.dll 1, 3, 0, 5
nv4cpl.dll 6.14.11.7580
nv4cuda.dll 6.14.11.7580
<more> 6.14.11.7580 (all)

Old driver: nv4_mini.sys 6.14.10.5351
nv4_disp.dll 6.14.10.5351
nv4cod.dll 1, 0, 0, 11
nv4cpl.dll 6.14.10.5351
<more> 6.14.10.5351 (all)

The old driver was digital signed, the new one is not. (I did not find a new signed one.)
The main reason to change the driver was a game (Crazy Machines 2) which did not render
properly with the old driver. After a long discussion with the game vendor's hotline I
did decide to try a new driver.

2) Today I am not able to copy the infomation before the temperatures vanishes.
However some days ago I could copy those values to clipboard before they vanished,
and I pasted the result to a text editor. Comparing this with the content of
the clipboard after vanishing I saw, that the only difference were two lines
with the temperature values. So there should not much information be missed today.

Thank you for the data. After the GPU temperature vanishes, please right-click on the bottom status bar of EVEREST main window --> Video Debug --> nVIDIA SMBus Dump. Copy-paste the full results into this topic.

Also right-click on the bottom status bar of EVEREST main window --> Video Debug --> nVIDIA GPU Registers. Copy-paste the full results into this topic.

Oops, here comes a PS.

I just read another thread in the forum
(http://www.lavalys.com/forum/index.php?showtopic=4442)
where you recommend to toggle the option
"nVIDIA GPU SMBus access through ForceWare".

I did try this, the option was not enabled.
After enabling it the missing GPU temperatures
do show up again.
So my problem seems to be solved. The only thing
I do not know is, what you would recommend under
normal circumstances, enabling the option or not.

Here is the new information from the
-> Computer -> Sensors site, but only as a kind of
diff dump:

Thank you for the feedback. That option is fine at both settings. When the option is disabled, EVEREST accesses nVIDIA GPU SMBus via direct calls. But apparently direct calls do not work 100% reliably on your configuration. When you enable that option, EVEREST switches from direct calls to driver (ForceWare) calls, and that usually fixes such GPU temperature measurement issues.

I guess the 34 vs. 35 is a measured temperature?

Thank you for the feedback. That option is fine at both settings. When the option is disabled, EVEREST accesses nVIDIA GPU SMBus via direct calls. But apparently direct calls do not work 100% reliably on your configuration. When you enable that option, EVEREST switches from direct calls to driver (ForceWare) calls, and that usually fixes such GPU temperature measurement issues.

Thank you for your kind help :-)
