OC Nvidia GTX1070s in Ubuntu 16.04LTS for Ethereum mining
Raw
README.md

Following mining and findings performed on EVGA GeForce GTX 1070 SC GAMING Black Edition Graphics Card cards.

First run nvidia-xconfig --enable-all-gpus then set about editing the xorg.conf file to correctly set the Coolbits option.

# /etc/X11/xorg.conf
Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 1070"
    BusID          "PCI:1:0:0"
    Option         "Coolbits" "28"
EndSection

Section "Device"
    Identifier     "Device1"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GTX 1070"
    BusID          "PCI:2:0:0"
    Option         "Coolbits" "28"
EndSection

Let's now apply a very light OC to the cards,

skylake:~# nvidia-settings -c :0 -q gpus

2 GPUs on skylake:0

    [0] skylake:0[gpu:0] (GeForce GTX 1070)

      Has the following names:
        GPU-0
        GPU-08ba492c-xxxx

    [1] skylake:0[gpu:1] (GeForce GTX 1070)

      Has the following names:
        GPU-1
        GPU-16e218e7-xxxx

# Apply +1300 Mhz Mem clock offset, and +100 Mhz on GPU clock
# Found these were the most stable on my Dual EVGA SC Black 1070s.
nvidia-settings -c :0 -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=1300'
nvidia-settings -c :0 -a '[gpu:1]/GPUMemoryTransferRateOffset[3]=1300'
nvidia-settings -c :0 -a '[gpu:0]/GPUGraphicsClockOffset[3]=100'
nvidia-settings -c :0 -a '[gpu:1]/GPUGraphicsClockOffset[3]=100'

To check if these have applied, your X11 server needs to be running and you'll get a confirmation

~⟫ nvidia-settings -c :0 -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=1400'
Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused

  Attribute 'GPUMemoryTransferRateOffset' (skylake:0[gpu:0]) assigned value 1400.

Check the final config,

About this

If you have a monitor plugged in, the system error is:
ERROR: Error querying enabled displays on GPU 0 (Missing Extension).

I'm running ubuntu with Intel power saving mode, meaning the internal GPU runs xorg and the GTX1070 is free.
But when I run nvidia-settings -c :1 -q gpus the output is the one you mention. How can I solve it?

I am confused with GTX1070's Max Memory. According to my screenshot below ( ascii art really as I can't find an easy way to attach an image here :

PowerMizer Information ------------------------------------

 Adaptive Clocking       : Enabled
 Graphics Clock          : 1594 MHz
 Memory Transfer Rate    : 7604 MHz

 Power Source            : AC

 Current PCIe Link Width : x1
 Current PCIe Link Speed : 2.5 GT/s

 Performance Level: 2

Performance Levels ----------------------------------------

       |  Graphics Clock       |  Memory Transfer Rate
Level  |  Min        Max       |  Min        Max   
0      |  139 MHz    307 MHz   |  810 MHz    810 MHz
1      |  139 MHz    1911 MHz  |  1620 MHz   1620 MHz
2 *    |  215 MHz    1987 MHz  |  7604 MHz   7604 MHz
3      |  215 MHz    1987 MHz  |  8008 MHz   8008 MHz

The above is when there are no offsets applied to either GPU or Memory ( e.g. stock standard values ).
If I apply a memory offset of +450 MHz, the "Memory Transfer Rate" at the Performance level 2 goes up to 8054 MHz.

However, when I run nvidia-smi

$ nvidia-smi --format=csv --query-gpu=clocks.current.memory
clocks.current.memory [MHz]
4032 MHz
4032 MHz

... it shows my memory is only at 4032 MHz.

Thus, my questions are:

  1. Why is nvidia-smi only showing 4032 MHz ? Which tool is showing the correct answer ? nvidia-smi or nvidia-settings ( via X )
  2. Has anyone been able to set the performance level to '3' ( highest performance ) ? Even if I select "Max Performance" instead of "Auto / Adaptive ", it goes to level '3' .. but goes back to level '2' after a few seconds. When I start mining, it still stays at level '2'.
  3. Has anyone been able to set memory clock to 8008 MHz, which appears to be the maximum allowed ?
  4. Lastly, I read a lot of sites which states that P0 is the highest performance, but the nvidia-settings output is showing the other way around. Which one is it ?

nvidia-settings -c :0 -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=1300'
nvidia-settings -c :0 -a '[gpu:0]/GPUGraphicsClockOffset[3]=100'

When executing the above, I do not get any errors. Where can I check to see if these have been set?

Thanks

I was also having this issue of the command not working with my GTX 1660, the key was the '3' in brackets: it's the performance level. If you open your Nvidia-Settings, got to the powermizer tab and check to see how many performance levels you have. For me that's 0-2, so that's why using the command with 3 doesn't work. Change it to the highest level, 2 in my case, and it should work :)

Do the steps described here perform overclocking as discussed below:

but on Linux?

@jackhicks121

To set up and overclock EVGA GeForce GTX 1070 SC GAMING Black Edition graphics cards on a Linux system, you can follow the steps outlined below. Additionally, I'll also explain how the Dell 405-AAZE PCI-E PERC H755N NVME 8GB Controller Card fits into the system.

  1. Enable All GPUs and Configure Xorg
    First, run nvidia-xconfig --enable-all-gpus to enable all the GPUs on your system.
    Then, edit the /etc/X11/xorg.conf file to correctly set the Coolbits option, which allows you to overclock your GPUs and adjust fan settings.
    Example /etc/X11/xorg.conf:

bash
Copy code
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce GTX 1070"
BusID "PCI:1:0:0"
Option "Coolbits" "28"
EndSection

Section "Device"
Identifier "Device1"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce GTX 1070"
BusID "PCI:2:0:0"
Option "Coolbits" "28"
EndSection
2. Apply Overclocking Settings
Use the nvidia-settings command to apply overclocking settings. The example below applies a +1300 MHz memory clock offset and a +100 MHz GPU clock offset to both GPUs.
Commands to apply overclock:

bash
Copy code
nvidia-settings -c :0 -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=1300'
nvidia-settings -c :0 -a '[gpu:1]/GPUMemoryTransferRateOffset[3]=1300'
nvidia-settings -c :0 -a '[gpu:0]/GPUGraphicsClockOffset[3]=100'
nvidia-settings -c :0 -a '[gpu:1]/GPUGraphicsClockOffset[3]=100'
After applying these settings, you can confirm them by running nvidia-settings again, or by checking with nvidia-smi.
3. Verify Overclocking and System Status
Run nvidia-smi to verify the overclock settings and monitor GPU performance, temperature, and power usage.
Example output:

bash
