Request It would be extremely beneficial to be able to monitor the GPU memory junction temperature on Linux through nvidia-smi or the NVML API. Background With the latest RTX 3080/3090 series cards using GDDR6X there are growing concerns relating to the temperature of the memory junction. It has been observed that generally performance is throttled at around 110C. As well as hitting this performance throttling, it would be great if Nvidia could expose this temperature through nvidia-smi/NVML API. As far as I know the capability to record these sensors definitely exists in the latest Windows drivers and is exposed through NVAPI. Presumably it’s also in the Linux drivers too, but if not can we get that functionality as well as query access in NVML API or the nvidia-smi tool? I know there are a bunch of people who want this functionality, so if you’re reading this and are one of them, please post your thoughts or confirm your agreement to convince Nvidia this is a priority.

I really want to voice in on the need for proper sensor data on Linux. Please help us on this!

Want to be another voice here. Still waiting. Either being able to see VRAM temps or being able to set the maximum VRAM temp (before throttling) would be helpful! VRAM temperatures are widely known to be an issue for gamers and creatives alike on 3080/90. Thanks.

@wpierce @nadeemm Why is so difficult to understand the issue, is so easy to replicate in linux: nvidia-smi dmon More than 6 months and not a real solution here, is really annoying, especially for us that invested thousand of dollars in your products. Why not to switch to AMD in the near future? Thanks…

I’m glad to find this thread hoping that Nvidia hears its customers. I agree with everyone else that Nvidia should enable Vram temp monitoring!!

Absolutely! @2024a please make this happen!

I have joined specifically to comment here. This has gotten ridiculous, @2024a can you please implement memory junction temperature readout in nvidia-smi (or nvrm, I don’t care)? The inability to monitor memory temps is going to end up costing a massive amount in warranty replacements. And booting into windows isn’t a workable solution (at least not for me) since duplicating my workload in windows isn’t feasible.

It sounds like Nvidia’s official position on monitoring memory temps in linux is WONTFIX. But I think everyone on this thread would like to understand why? This data point already exists on windows, so obviously the hardware provides it. Is there a technical reason for omitting it on linux or are Nvidia just treating linux as a second class citizen?

Hi, For a given GPU, nvidia-smi output is the same between Windows and Linux. Here is the output on an RTX 2080: Windows C:\>nvidia-smi dmon -s p # gpu pwr gtemp mtemp # Idx W C C 0 12 42 - 0 11 42 - 0 6 41 - Linux wpierce: ~$ nvidia-smi dmon -s p # gpu pwr gtemp mtemp # Idx W C C 0 5 42 - 0 5 42 - 0 6 42 - mtemp output from nvidia-smi is not memory junction temperature. The reported temperature is the hottest recorded across all HBM temperature sensors. It is only supported on SKUs with HBM memory. @nadeemm will explain more about what memory temperatures are exposed and why.

Thank you for the info. From my limited experience with windows (full time linux user here) windows tools are able to monitor these values Here’s an example with hwinfo showing “GPU Memory Junction Temperature”: [How To Check Vram Temperature On Graphic Card] Here’s an example with GPU-z including both “Hot Spot” and “Memory Temperature” at (2:28s): [3080 / 3090 Memory Junction Temps FIX GUIDE] I understand that these data points are not available to us on linux, but I don’t understand why. If the hardware didn’t support it, then I’m really confused about what the windows GPU monitoring tools are reporting. Why isn’t it possible to get these same data points on linux? I hope @nadeemm will be able to speak to this. Thanks

Hi, nvidia can you FFS show the memtemp in linux? thx
