Power Limit on 3000 Mobile Series

Is there a way to increase or decrease power limit on Mobile Ampere series GPUs? I have a laptop with RTX3080M but nvidia-smi says “Changing power management limit is not supported for GPU: 00000000:01:00.0.”. It is very easy to enable/disable turbo boost and other features also set target TGP values on Windows but not on Linux. Why? Is Nvidia planning anything for the next update? At least give an option to disable turbo boost or limit TGP.

Facing the same issue with mobile RTX 3060.

Can you please share the output of cat /proc/driver/nvidia/gpus/0000:01:00.0/power here?

Also, when running a game/benchmark, can you share the power draw, i.e. the output of watch nvidia-smi?

Also please mention the rated limit by the laptop manufacturer. Thanks

This laptop: TUXEDO Stellaris 15 - 15.6'' WQHD IPS + AMD Ryzen 9 5900HX, Intel Core i7-11800H + NVIDIA GeForce RTX 3080 + 2x M.2 NVMe SSD + max. 64GB RAM - TUXEDO Stellaris 15 - Gen3 - TUXEDO Computers
Also should be identical to this: XMG NEO 15 Gaming Laptop with RTX 3080 and Ryzen 9 | bestware

My laptop has Ryzen 5900HX and RTX3080 16GB, and the GPU should be Max-P model. According to the product page I should be able to get 150W+15W TGP with GPU. XMG users report that they get 165W from their GPUs on Windows. On Tuxedo’s page they say:

(NVIDIA currently allows a **maximum of 115 W TGP under Linux** . We are already in close contact with NVIDIA to improve the NVIDIA graphics driver as soon as possible and will deliver it via the system updates!)

Why? :(

Hi. Dell G15-5510 laptop (RTX 3060), same thing here, 80W max.

It should be able to reach 115W (for Ryzen) or 80W (for Intel). Plus 10W Dynamic Boost. Is it Intel or Ryzen for you?

Intel Core i7 10870H.

Power Limit Default says 80000 mW
GravityMark (vulkan) shows 78-80W

Can you please share also the output of cat /proc/driver/nvidia/gpus/0000:01:00.0/information ? Thanks.

I was searching a little bit more to find where may be problem. In your laptop (what a beast !) are power levels for dGPU configured and saved in VBIOS (Tongfang ?), default target value is set to only 115W, but limit value says 165W (what technically means: 150W Max. Base + 15W Boost), as shows picture.

Can you please provide PN or ordering number of your laptop (not SN !), it looks like it is Clevo based product, and I will find some possible solutions for you, if there are any…

Yeah, I found that page too. It is possible to reach 165W on Windows, but not on Linux. Also, that’s a Tongfang laptop, not Clevo. I checked that PN is like gm5zg8wXXXXXXXX, but only gm5zg8w gives results on Google.

Yes, but Clevo is OEM laptop manufacturer, and probably brands like Tongfang, XMG, Mechrevo, Eluktronics, Medion and all others are sharing same HW platform, which is good for you, because I have found verified Clevo VBIOS for RTX3080 16GB with 150W Base power level. VBIOS reflashing is possible…

Sounds good but risky. I would do it if I were to own proper equipment for unbricking. Thanks anyway.

Also, there are power profiles on my BIOS but I think they change target TDP values, not the base TDP. Since the base TDP is hard coded it is not possible to modify it via BIOS settings. Also, I fouınd that there are some acpi calls to change some settings but it doesn’t look possible to modify the current TDP value. It looks possible to hand over responsibility to modify current TDP but not the ability to modify the value itself. And looks like Nvidia Driver is responsible for this task, but this feature has not been implemented for Ampere GPUs yet.

I hope this feature is on Nvidia’s to-do list. Any comments from Nvidia Devs?

I would add my request as well, as the driver should be able to handle undervolt/tgp/frequency, as this is supported on Windows.

Aside, I believe it should be possible to safely modify the VBios when using Optimus, as in case of errors the system would work normally and should be able to restore the backup vbios.
Any idea where to start modifying it? Unfortunately, I don’t have knowledge of Nvidia bios hacking…

Undervolting would be very nice.

About modifying bios; desktop GPUs may have dual BIOS chips and a button to switch between them, but laptops are more complicated. It wouldn’t be wise to risk your GPU in the era of silicon shortage and you may probably end up in a forum opening a post about your bricked mobile GPU if you don’t know what to do.

VBIOS modifications as of Kepler/Maxwell gen are not possible due to:

  1. Lack of HEX editors of .ROM files,
  2. Every VBIOS needs to be signed, if not it will not be loaded into GPU.

Your VBIOS (Dell) shows only 80W Target and 90W Limit, whats technically 80W Base + 10W Boost, and probably there is nothing to gain in terms of Max. TGP…

Modifying VBIOS is a risky route to take and ideally it ought to be handled by the drivers as it is on Windows.
