I am trying to overclock a Nvidia graphics card.
Ubuntu 16.04.2 LTS + NVIDIA Driver Version: 384.47
After editing /etc/X11/xorg.conf
Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BusID "PCI:1:0:0" Option "Coolbits" "28" Option "AllowEmptyInitialConfiguration" EndSection
(PCI Bus matches up with the device)
Rebooting, and then trying to adjust settings using nvidia-settings, I get:
ERROR: Error parsing assignment '[gpu0]GPUPowerMizerMode=1' (Missing attribute name). ERROR: Error parsing assignment '[gpu0]GPUMemoryTransferRateOffset=1600' (Missing attribute name). ERROR: Error parsing assignment '[gpu0]GPUGraphicsClockOffset=100' (Missing attribute name).
The additional overclocking options are not available in the GUI of nvidia-settings either.
I have tried different drivers versions, reinstalled Ubuntu about 6 times using various GUI's and package options.
I managed to get this right on 1 previous machine, but I can't for the life of me remember what I did.
I suspect that Coolbits is not being activated, but don't know how to confirm this.
