EWBF's CUDA Zcash miner

[Nokia555]

I added support for EWBF auto-restart when getting 0 sol/s error aka GPU error.

I seem to be getting a much lower hashrate than others using the 1070.

Code:

Temp: GPU0: 58C GPU1: 59C GPU2: 61C GPU3: 64C GPU4: 60C 
GPU0: 176 Sol/s GPU1: 189 Sol/s GPU2: 187 Sol/s GPU3: 190 Sol/s GPU4: 188 Sol/s 
Total speed: 930 Sol/s

This is on ubunutu 16.04 and im running it as follows
./miner --server zec.suprnova.cc --user XXXX.XXX --pass x --port 2142  --cuda_devices 0 1 2 3 4

How can I troubleshoot this?

What are your overclock settings.
Should be getting 400+ sol/s card at the very least

No OC is that the issue? Im running it on a headless server and could not find any instructions related to overclocking without a desktop environment.

Ive searched the Post, how do i Setup Separate Instances on EWBF miner?

In Genoil Eth miner is --cuda devices 0 1 2  etc


What should I type on the .bat file?


its --cuda_devices 0 1 2

Yes you need to overclock to see if its the cards or not.

Try these instructions:
Needed to install Nvidia driver 375.20.

Install Ubuntu 16.04 with enabling software update options for Ubuntu Development team and third parties.

On reboot, after installation open up Ubuntu Software - update the the OS and reboot.

So, first install the default Nvidia driver through Software & Updates, and then Additional Drivers. The Ubuntu Nvidia 367.57 driver includes extra tweaks from the Ubuntu development team for maximum GPU performance.

Reboot.

Now switch back to the non-Nvidia drivers in Software & Updates.

Reboot.

Now, you can install the latest Nvidia drivers and get the maximum GPU performance.

Press Ctrl+Alt+F2 to get into a text-only console.

Log in.

Switch off x-server with:

sudo service lightdm stop.
Got to Downloads folder with:

cd ~/Downloads
ls
This will display driver name and run with:

sudo sh ./AND NVIDIA NAME LISTED
There will be two error messages, but ignore them and say yes at the prompts.

Then, switch the x-server back on with:

sudo service lightdm start
Reboot PC.

Then run this in terminal:

sudo update-grub
sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration
Finally, you can enter overclocking settings and fan controls by creating startup .sh file by copying and pasting this into empty document amending for desired fans speed and clock settings.

To finish, you will create a startup .sh file for each GPU so the overclock settings and fan speed are loaded when you login to Ubuntu 16.04.

Create some empty documents on Ubuntu Desktop and call them whatever you like. Make sure the filename has .sh at the end.

Paste in:

#!/bin/bash

nvidia-settings -a '[gpu:0]/GPUGraphicsMemoryOffset[3]=100'
nvidia-settings -a '[gpu:0]/GPUMemoryTransferRateOffset[3]=100'
nvidia-settings -a '[gpu:0]/GPUFanControlState=1'
nvidia-settings -a '[fan:0]/GPUTargetFanSpeed=30'
Amend the clocks (GPU and Memory) and fan speeds to whatever are you comfortable with. Make separate documents for each GPU by changing the numbers for each card.

Save and open properties and make each file "executable".

Then open the Dash and find Startup Applications, and add these files to the programs you run when you start up the Ubuntu 16.04 desktop.

Reboot and fans and overclocks will load up with no hassle.

Let me know if that works for you.

Here is another link to overclock gpus in ubuntu:

Problem with Temp what to do?


1060 3gb   Only on some cards  i have 70% but its still going to 82c

If lowering powerlimit doesn't help try some small fans or buy some 220/110 v fans to suck the heat from both sides of heated gpus.

Hi EWBF and all,

I'm getting lots of rejected share on a particular gpu out of 7 gpu.
Is that normal?

edit: im using gtx1070

Do i have to do some settings with the intensity of the gpu? What is the usual setting to be set for intensity?

Please help.

thankyou!

Hey guys, check this out! https://bitcointalk.org/index.php?topic=2071108.0  Beautifull work, just beautifull.

Thanks for posting this!!!
Hopefully this works just started using it.

Added option --fee developer fee control.

as i understand i can put 0 dev fee now?

[CryptoWatcher420]

Added option --fee developer fee control.

as i understand i can put 0 dev fee now?

sure for a reduced hashrate speed

There is really no evidence that changing the dev fee has any effect on the hashrate.  Will consider adding the dev fee back to my miners when we have an active dev....

Ive been trying to backread the thread but cant find confirmation, can EWBF run AMD cards as well?

This is only a CUDA miner as stated in the name of this thread.

Thanks i am getting 470 Sol / s on my 1070 Asus strix 8G ROG

Thanks i am getting 470 Sol / s on my 1070 Asus strix 8G ROG

I have 4 of 1070 strix's running anywhere from 450 to 470 Sol / s.  Using 75 TDP, +125 Core, +700 Memory w MSI Afterburner.  What settings are you using?

I am running 6 GPU, installed latest driver and using gpu tweak changed GPU clock 1906 and Memory clock 8468
