Overclocking NVIDIA on linux
First you need install nvidia drivers, you can download some from nvidia site or use ppa which works for me.
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-384
Next you can install extra cuda drivers.

Checkout nvidia-settings
root@min01:~/bin# nvidia-settings -c :0 -q gpus
Failed to connect to Mir: Failed to connect to server socket: No such file or directory

3 GPUs on min01:0

Has the following names:
GPU-0

If you see

If you need ebin for fake monitor use this command for installing and making copy of your main screen
sudo apt install read-edid edid-decode
# the integer after -m is the monitor id, starting from zero and incrementing by one. sudo get-edid -m 0 > edid.bin # View the output of this command and verify you have the right monitor. # You can tell via the vendor, resolutions, serial number, all that jazz. cat edid.bin | edid-decode original tutorial http://kodi.wiki/view/Creating_and_using_edid.bin_via_xorg.conf Now you can move your edid into X11 folder cp edid.bin /etc/X11/ after this you can change X11 config For enable overclocking you need set coolbits which control this stuff
The Coolbits value is the sum of its component bits in the binary numeral system. The component bits are:
1(bit 0) - Enables overclocking of older (pre-Fermi) cores on the Clock Frequencies page in nvidia-settings.2(bit 1) - When this bit is set, the driver will "attempt to initialize SLI when using GPUs with different amounts of video memory".4(bit 2) - Enables manual configuration of GPU fan speed on the Thermal Monitor page in nvidia-settings.8(bit 3) - Enables overclocking on the PowerMizer page in nvidia-settings. Available since version 337.12 for the Fermi architecture and newer.[2]16(bit 4) - Enables overvoltage using nvidia-settings CLI options. Available since version 346.16 for the Fermi architecture and newer.[3]
To enable multiple features, add the Coolbits values together. For example, to enable overclocking and overvoltage of Fermi cores, set Option "Coolbits" "24".

Finally you can change card props like this
# Apply +850 Mhz Mem clock offset, and +100 Mhz on GPU clocknvidia-settings -c :0 -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=850'nvidia-settings -c :0 -a '[gpu:0]/GPUGraphicsClockOffset[3]=100'
Change PowerLimit
