I got this message when ran nvidia-smi:

Hello
I'm sending this message with google translate.
When the ubuntu is switched on, I can operate the terminal automatically.
but when sudo is given the command prompts me for the password.
How can I prevent the password from prompting?
I want the sudo command to run without asking for the password.
As is the NVOC.
how can I do that.

Ubuntu 18.04

This should do the trick

Code:

sudo visudo

Append the following to run ALL command without a password for user named john:

Code:

john ALL=(ALL) NOPASSWD:ALL

Did you restart your session after appending the line ?

nvOC image is created by fullzero, I have no idea how he done it.
Will check and see if I can find how its done in nvOC.

Yes, we have something like that for m1 user.

Thanks for clarify
Yup, its in "/etc/sudoers.d/90-m1"

Code:

m1@m1-desktop:~$ sudo cat /etc/sudoers.d/90-m1

I'm having a problem on new flashed images where the miner temp control bugs out and causes Nvidia driver errors? Tried flashing multiple versions of nvOC. Any thoughts?

I cross posted this to the discord bug reports with images. Can't post photos here yet as my account is newb


So I reverted to loading from disk image 19-2.1 and it is working fine now. I had previously been loading from image 19-3.X

There were no issues until recently.

It looks like an Nvidia driver update before rebooting error, have you tried rebooting the rig and see if it still gives that error?

If anyone wonders. nvOC supports up to 19 GPUs with ASUS B250 Mining Expert. nvOC supports Nvidia P106 and P104 mining cards.

Tried to upgrade T-Rex to cuda 10 version.
extracted 9.2 to fresh directory and made symblic link:

nvOC images dont have cuda-10 pre installed you should install cuda 10

[Tigel]

nvOC images dont have cuda-10 pre installed you should install cuda 10

Did that, thanks!!
Also it seems I had forgot to copy nvoc-miner.json over from t-rex 0.9.2 cuda directory.

Why the algo_specific_oc is not working ?

the hashrate is the same as OC core=0 and mem=0

My system is based on nvOC_19-3.x_U16.04_Cuda_8-9.2_N410_2018-10-27.7z and on the automated upgrades (NVOC V0019-3.2)

Run this command to check the core and mem values with and without oc :

Code:

bash ~/NVOC/mining/nvOC gpuinfo

Thank you so much Papampi

[akokkon]

as i wrote before the gpuinfo prints the same results before and after algo_specific _oc

Does it show nvidia-settings applying OC values after miner restart on gnome-terminal?

Please set OVERCLOCK_MODE to " NO", "GLOBAL" and "ALGO_SPECIFIC" with different values.
Restart NVOC after editing 1bash with:

Code:

bash ~/NVOC/mining/nvOC restart

Check if gnome-terminal shows nvidia-settings applying OC values or not

Run report command after every nvOC restart and post results.

Code:

bash ~/NVOC/mining/nvOC report
