Hello,

Went through this guide to OC my 1060 cards, but was not able to do it.

After this command "sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration", on Reboot xorg.conf file is being reset to default. Coolbits option was not found in the file Huh

and Overclocking is not enabled on GPU's.
Is there any possible solution for this? Please let me know.. Thanks

Using Ubuntu 16.04, nvidia-384 drivers.
xorg.conf file after coolbits command:

Code:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 384.90 (buildmeister@swio-display-x86-rhel47-05) Tue Sep 19 18:13:03 PDT 2017

This method was tested with Ubuntu validated 378 drivers - performance level with 384 drivers is worse and they generate more heat per card.

I did put a workaround for this problem:

Firstly, log in and enable overclocking on one GPU:

sudo nvidia-xconfig -a --cool-bits=28

Log out and then log back in, then enable overclocking on all the other identical GPUs:

sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration

Then log out and log back in and all the GPUs will have overclocking and fan control enabled.
