3090 power throttles around 300w

I just noticed using mangohud that my 3090 is power throttling already around 300w.
I have not had this warning turned on before so I do not know if this has been an issue over time but I have experienced complete crashes on my gpu while for example gaming or generating images using SD.

Then 2 days ago a game crashed, and my gpu did no longer show even on lspci. Rebooting or shutting off the computer/turning it back on did not help, but for some reason removing it from my computer and reseating it again made it come back and that is when I started looking into power consumption and levels.

nvidia-smi -q tells me max should be 350w (366w), not 300w.

I have a 1000w PSU.
The only thing recently changed is me adding a samsung 990pro m2 and I used one of the pci lanes instead of cpu if that could be related?

I DID notice that one of the lines on the gpu was a mm shorter than the rest, if that could be related?

Please advice, I still have warranty on the card (and the mobo if you guys think it is that)

The contact being shorter is normal, to allow for pcie hotplug.
Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Thank you for replying so fast.

This is on a Manjaro-unstable using kernel 6.8 and x11.
Using latest firmware (F22) on mobo.
If you want me I can also run it on a pure arch install, using wayland, with the card actually used when running the script (I use prime) etc. Just let me know. :)

The temperature is at 49°C while idle, please monitor temperatures under load.

I was gaming just before. :)
It never goes higher than 75-80c even at a 90-100% load over long time, that is why I started suspecting power consumption and included the “check” in mangohud.
And when power goes just a tiny bit above 300w a big red warning stating “power throttling” and shows spikes in the frametime histogram.
vsync is on, that is why it is locked at 60 on my old a** monitor. xD

$ nvidia-smi -q -d POWER

Or am I understanding this wrong here somehow and it SHOULD throttle already at 300w?
I’m a bit nervous using the card to full potential now, and I do still have warranty…

I wouldn’t know why, if it shows 350W, it should go up to 350W. Maybe check nvidia-smi -q while throttling what reason is displayed.

Thank you again for responding.
nvidia-smi -q lists nothing as throttling. It just shows the same temperature and power consumption as mangohud.
I wonder where mangohud is getting the information that the GPU is throttling?
I did notice 300w is not the limit, it is below that, around 29x something.

I would not be so worried if it wasn’t that the GPU completely died on me a few days ago. I payed a LOT OF MONEY to nvidia for this GPU!!! More money for that GPU than I payed for any complete computer in my entire life, and I have owned computers since late 1980.

Here is another nvidia bug report (this time on a pure arch install) ran while mangohud was constantly reporting “THROTTLING POWER”
nvidia-bug-report.log.gz (896.2 KB)

Thanks in advance from a VERY worried Nvidia user. :(

Previously, this was called “Throttling Reasons” which made more sense.
So it’s really the driver that’s limiting it. Only reasons I could think of were either a driver bug or, since you’re running in PRIME mode without monitors connected to the nvidia gpu, 50W reserved for the display engines. Far-fetched, though.

I was contemplating including the information above, but you figured it out anyway. :)
The reason is I HAVE to connect my monitor to my mobo hdmi to get reverse prime to work (otherwise everything would run on the nvidia rather than on my CPU, xrandr doesn’t want to move the ouput on this machine for some reason, neither on x11 nor on wayland)

What I could do to further test this is to connect my monitor to the nvidia and retry and see if it still throttles. Maybe there is a limit how much it can consume while having to “reroute” the signal to my mobo hdmi…

So @generix I connected the monitor to a port on the GPU, ran the debug tool, started a demanding game and debug one more time:
nvidia-bug-report-nv_hdmi.log.gz (924.7 KB)
nvidia-bug-report-nv_hdmi-game.log.gz (958.9 KB)

I had to go x11 since wayland bugged out completely, visual bugs everywhere, flickering in steam and game freezing on load. :-/

I added fan speed in mangohud yesterday, and it seems to work fine when in reverse prime, usually running at 65-85% when gaming.
But look at this when I used the GPU hdmi!
Something fishy is going on here.
Could be mangohud though, idk.
Maybe you see something more in the logs?

Edit 2
Maybe this information could be useful:
