Nvidia GPU Overclocking OC In Linux

Note:

Optimizing GPU to its peak means getting maximum out of it and stressing it more. According to me, OC will reduce the life of the GPU. Hence please tune the GPU with some benchmarking tool. Double check GPU temperature. I am keeping the power to as low as possible especially for 1060 which actually give you good hasrate.

Enable GPU tuning using nvidia-settings utility

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

For headless systems, you should configure xorg with dummy configuration

     sudo nvidia-xconfig -a --force-generate --allow-empty-initial-configuration --cool-bits=28 --no-sli --connected-monitor="DFP-0"

Tuning Power Consumption for 1070/1060/1050ti

GTX 1070 (Expected Hash rate for ETH ~30 MH/s):

     nvidia-smi -pm 1
     nvidia-smi -pl 110

GTX 1060 (Expected Hash rate for ETH ~22 MH/s):

     nvidia-smi -pm 1
     nvidia-smi -pl 90

GTX 1050 Ti (Expected Hash rate for ETH ~13.1 MH/s):

     nvidia-smi -pm 1
     nvidia-smi -pl 60

Setting FAN speed and Memory clock speed. Similarly, do it for all GPU available in the system

GTX 1070 (~30 MH/s Solo ETH):

     sudo nvidia-settings -c :0 -a [gpu:0]/GPUMemoryTransferRateOffset[3]=1100
     sudo nvidia-settings -c :0 -a [gpu:0]/GPUGraphicsClockOffset[3]=-200
     sudo nvidia-settings -c :0 -a [gpu:0]/GPUFanControlState=1
     sudo nvidia-settings -c :0 -a [fan:0]/GPUTargetFanSpeed=80

GTX 1060 (~21.5 MH/s Solo ETH):

     sudo nvidia-settings -c :0 -a [gpu:0]/GPUMemoryTransferRateOffset[3]=1600
     sudo nvidia-settings -c :0 -a [gpu:0]/GPUGraphicsClockOffset[3]=-160
     sudo nvidia-settings -c :0 -a [gpu:0]/GPUFanControlState=1
     sudo nvidia-settings -c :0 -a [fan:0]/GPUTargetFanSpeed=80

GTX 1050 Ti (~13.1 MH/s Solo ETH):

     sudo nvidia-settings -c :0 -a [gpu:0]/GPUMemoryTransferRateOffset[2]=600
     sudo nvidia-settings -c :0 -a [gpu:0]/GPUGraphicsClockOffset[2]=-100
     sudo nvidia-settings -c :0 -a [gpu:0]/GPUFanControlState=1
     sudo nvidia-settings -c :0 -a [fan:0]/GPUTargetFanSpeed=80
