help activating coolbits 4, and 8

[Snowarch]

I want to use green with envy to overclock my nvidia p104-100 gpu from 1887mhz to 1900mhz, but it says i need coolbits. i tried a command but it froze my terminal. os is ubuntu 16.04. cpu is 8086k +750 watt psu. so shouldn't be bottleneck 

[Nayr438]

This command should work

sudo nvidia-xconfig --cool-bits=12

 

Otherwise

/etc/X11/xorg.conf.d/20-nvidia.conf

 

Section "Device"
        Identifier "Nvidia Card"
        Driver "nvidia"
        VendorName "NVIDIA Corporation"
        Option "Coolbits" "12"
EndSection

 

You can also check /etc/X11/xorg.conf to see if it already has a Device Section Generated for NVIDIA, then just add the coolbits line.

 

Reboot or restart X after the change is made.

But I've never managed to enable an overclock on Linux without a freeze even though it works perfectly in Windows.

Honestly, its not like such a small overclock as you are proposing is likely to be measurable.  I only did it for fan control as for some bizarre reason my default fan profile tops out at 32% causing thermal throttling under load.

[Snowarch]

i should of been more spasific. my fans get 65%, 70 degrees consistant 1887mhz under benchmark.

 

anywhere else about 50% fan speed, 56-ish degrees 1887 mhz graphics clock. so there definatly a small ammount room for overclock. i know nothing of overclocking, so i don't know whats safe, so could potentually go more. my gpu it says can draw 180watt power max, but it draws 90watts according to green with envy so theres even more room. if y'all can suggest a safe overclock i can try more.

 

1907mhz is stock, but it throttles down to 1887mhz automatically.  mainly want to increase the fan curve to at least get the stock if overclocking isn't suggested.

 

i'll screenshot when i can @Nayr438 @Alex Atkin UK

overclocking should be fine as long as your not adjusting voltage. @Alex Atkin UK above has coolbits 28 which enables voltage control, not sure if the NVIDIA Bios limits that or not. As long as you stick with coolbits 12 you should be safe. 

 

As far as a overclock I have no idea and couldn't recommend anything.

 

If coolbits or GWE isn't working, it could be a a broken NVIDIA feature or a incompatibility with your current Kernel or Xorg build. During the time I had my 1060, I had fairly inconsistent results from update to update with stability. Could also be something wrong with GWE or another incompatibility with your current Driver. Most software targets the most recent driver revisions, so if your not on the latest driver and kernel for your distro, I would start with that.

[Snowarch]

driver 418 is the best i can do/what i use. 430 is the latest in the ppa, but steam itself is broken cause of opengl32.so nissing on it  so its kinda impossible to use 430. @Nayr438

You don’t have to use Green with Envy. Once you have the Coolbits set you should be able to add a Graphics and Memory Card Clock Offset or a manual fan percentage using the NVidia Control Panel in X.

[Snowarch]

@Nayr438 help! this happened . this is a 1080p screen... running and stuck at 720 x 480p its scaled really badly too. that was the first command you recommended.

from 1887mhz to 1900mhz

That's 13MHz, or 0.7% benefit.

You'd gain more by staring at the screen a bit harder.

[Snowarch]

@Kilrah i said i may overclock a lot more, but now im just worried about fixing my pc... look at the post before yours and the screen shots. can you help me? 720 x 300 something is a brick, i need 1080p back

 

nevermind, someone helped me fix it

[Nayr438]

delete /etc/X11/xorg.conf Whatever nvidia set for you display isn't compatible.

Create the /etc/X11/xorg.conf.d/20-nvidia.conf file as shown above. xorg.conf is considered depreciated anyways.

[Snowarch]

well, deleting the old file as sudo seamed to fix my resolution,

 

[Snowarch]

@Nayr438 this is m,y xconfig file

I'd actually never heard of Green with Envy, so glad to have custom fan curves on Linux, finally.

I didn't even get to use green with envy. coolbits messed up my pc, so after having help deleting the bad config that forced my resolution to 360 x 720,coolbits was gone, last post with a screenshot  was my fixed xorg config. how do i add coolbits aka the fan custom curve correctly to my xorg config? the fan thing is what i needed sonce the first post. overclocking was just a secondary idea. 

 

what do you mean by "so glad to have custom fan curves on linux" such a thing isn't possible without that coolbits thing added. using driver 418.

 

@Alex Atkin UK

[Nayr438]

Under Section "Device" for nvidia add

Option "Coolbits" "12"

 

Fan Control is controlled by nvidia-settings and I think only accept static values on its own. You can set it from the nvidia-settings control panel.

Something like Green With Envy just monitors your temp output and issues the static value based on your curve.

i saw that during the time my resolution wad bugged. If coolbits doesn't break my screen again, control pannel looked easier than gwe

I installed GWE on Fedora 32 after seeing it mentioned on this thread and it was dead easy, it "just worked".

 

I even was able to crank up the power target to max and add a 100Mhz overclock without F@H dying (RTX 2080 @ 1905Mhz).  Of course the biggest improvement is the custom fan curve so it doesn't roast if I forget to crank up the fan before folding, or sound like a tornado if I forget to switch to auto when NOT folding.  Very pleased with the result.

[Snowarch]

@Nayr438 tried adding the command to config manually, it won't edit it. says read only

[Nayr438]

You need to edit it as root or wheel using sudo.

sudo nano /path_of_file.

ctr+x to close nano, yes when prompted to save.

[Snowarch]

i could edit the file with gedit, but not save. how do you even use gedit as root?

From a terminal -> sudo gedit

@Nayr438 coolbits and overclocking work like a charm now thanks. quick question tho, whats better for gaming to overclock, the graphics clock or memory? 

 

and is 50% fan speed at minimum tempeture, and 100% at 70+ degrees good?

I usually notice more gains in the core, but memory can have some improvements. The memory will come down to brand, Samsung usually overclocks better, and both will depend on the silicon lottery.

Start with the core clock, once you find a stable overclock move onto memory. Just don't start adjusting both at the same time, unless you want to waste more time later.

 

Fan speed, will be your preference, as long as the card isn't hitting around 80c, you are good.
