GPU Ambient Temp: Latest beta build

[StackOverflow13]

I just noticed that GPU ambient seems to be missing from sensor panel in the latest beta. Was this removed on purpose? Can we get it back?T

Thanks

Is it only missing from the SensorPanel? Is it still there on the Computer / Sensor page?

BTW, what video card(s) do you have?

Thanks,

Fiery

I have 2 x gtx 680 SLI MSI Lightning. It's missing from all pages. Main page, (Under Sensor), OSD & sensor panel

This sensor has never been present on aida64 with GTX 680's.

Thanks for letting me know, v good of you. That's a shame. still least of my problems right now as I can't even run aida64.

[StackOverflow13]

Update: actually it is, at least on my one in the latest beta. However vrm & memory temperature sensors are missing

[Fiery]

GTX680 cards do not feature a sensor chip. On video cards you need a sensor chip to monitor such temperature readings as GPU ambient, GPU memory or GPU VRM.

Thanks for the reply, so what's showing under gpu ambient on sensor panel then? It's different from gpu diode.

Maybe your particular GTX680 card does have a sensor chip -- while most GTX680 cards do not. Please right-click on the bottom status bar of AIDA64 main window --> Video Debug --> nVIDIA SMBus Dump. Copy-paste the full results into this topic. Using that dump we can check what's up about sensor chips and other readings on your video card

Here you go: FYI they are 2x msi gtx 680 lightning sli

Thank you. Your cards feature a Nuvoton sensor chip that provides 2 temperature readings (GPU and GPU Ambient) on top of the GPU Diode reading that is provided by the GTX680 GPU chip itself.

Thanks you for the update. Before I flash my bios for UEFI ability from SI the card was also showing VRM & Mem temp these are no gone. how come, I'm assuming the chips are still there but the gpu bios is not reporting them????

[Fiery]

In theory the onboard CHiL CHL8266 power controller chip could also monitor a temperature reading (GPU VRM), but on GTX580 and GTX680 cards that reading is stuck at a fixed value, so AIDA64 doesn't display that temperature reading. I have no idea where GPU Memory could come from though

[StackOverflow13]

Thanks again for the prompt reply. werd afterburner shows fluctuating vrm & mem temperature readings not fixed?

[Fiery]

Maybe it calls the GPU temperature (the one that AIDA64 labels as "GPU") as GPU Memory; and it calls the GPU Ambient temperature as GPU VRM?

[StackOverflow13]

Don't think so all listed seperatly. 3 seperate readings. Gpu diode on aida matches gpu in msi. Abient seems to be the same as VRM temp in msi, so which is it do you think (in aida) is ambient actually = VRM?. Still missing mem though.

[Fiery]

Your card have 2 chips (Nuvoton and CHiL), and they provide 3 readings in total, but AIDA64 only shows the 2 readings for the Nuvoton chip. If you could post 2 new nVIDIA SMBus Dumps, one when the card is at idle and running relatively cool, and another one where the card is after a heavy load (like after running 3DMark or a 3D game), we could check the VRM temperature readings (provided by the CHiL chip), because there's a chance on your card that reading is not stuck like on most GTX580/GTX680 cards.

Hope this helps

sorry forgot one

Thank you. Unfortunately the GPU VRM reading provided by CHL8266 is invalid in both cases.

[StackOverflow13]

oh so whats msi reporting, is it mem temp?

[Fiery]

No idea... Probably only MSI knows.

[StackOverflow13]

oh well thanks for looking into it.
