Unable to change power limit with nvidia-smi

[machinedgod]

NVIDIA Open GPU Kernel Modules Version

530.41.03-1

Does this happen with the proprietary driver (of the same version) as well?

Yes

Operating System and Version

Arch Linux

Kernel Release

Linux 6.2.8-arch1-1 #1 SMP PREEMPT_DYNAMIC Wed, 22 Mar 2023 22:52:35 +0000 x86_64 GNU/Linux

Hardware: GPU

GPU 0: NVIDIA GeForce RTX 2060 (UUID: GPU-2f685ce6-33f4-db75-ce05-81d1723a6ddb)

Describe the bug

Before recent update, I was able to execute:
~$ sudo nvidia-smi --power-limit 60

and have it work as expected.

After update, this is the output:

Changing power management limit is not supported for GPU: 00000000:01:00.0.
Treating as warning and moving on.
All done.

Changing power limits caused observable changes both in temperature and in performance, so I am pretty sure my GPU supports it.

For context:
I found that default power limit of 80W tends to heat up the GPU enough that it starts throttling itself and cause stuttering - 60W seemed to work perfectly and keep it under 63C during everything, without boosting my fan. The computer itself is a laptop (which explains issues with heat dissipation), a Lenovo Legion Y740, and I have a pretty good cooling pad to help out.

To Reproduce

~# nvidia-smi --power-limit 60

More Info

Just a bit more context:
you may notice that in my Xorg config, I use option to skip EDID check for HDMI-0 output - the reason why, is because either driver doesn't recognize my (about 7y old) monitor, or the checksum that monitor outputs is invalid, and then it wouldn't let me use FullHD resolution on that monitor.

No idea if this is in any way related (I presume its) not, but this setup worked for over 5-6 months, so I doubt its related.

I also cannot change the power limit with nvidia-smi on this driver while i can on 525 series (I have a RTX 3050 laptop)

On 530 it says "Changing power limit is not supported for this GPU)

So which is intended behavior , make up your mind NVIDIA

I really hope its not the ladder because of this fun issue which also happens to me #435

Oh so its a wide-reaching problem, not just for 2060 and 3050.
I suppose visibility on it is nice enough, so should probably be fixed soonish.

With 530.30.02 (beta) the power limits were working fine for the first time on my laptop with a RTX 2060 Mobile 6GB. It broke after 530.42.03 update.

[xiguayuyichao]

Using the 525 version of the driver, my RTX3060 is able to limit power for the first time, but since updating the 530 version of the driver, it has been impossible to limit power

If anybody here is using a lenovo gaming laptop with the 530 drivers
Can anyone confirm this other power limit issue #492

[youmukonpaku1337]

got same issue

[youmukonpaku1337]

on a 3060 AMD legion 5

[kraskden]

Legion S7 15ACH6 / AMD Ryzen 7 5800H / NVIDIA GeForce RTX 3060

Same issue

[youmukonpaku1337]

driver version?

Legion S7 15ACH6 / AMD Ryzen 7 5800H / NVIDIA GeForce RTX 3060

Same issue

[kraskden]

driver version?

530.41.03-15

[youmukonpaku1337]

driver version?

530.41.03-15

try 535 beta

[youmukonpaku1337]

unless it doesn't exist for okm then test proprietary

Still have the issue on 535 BETA proprietary which is the only one with the "fix" i think
