VCRUNTIME140.DLL Error When Running XMR-STAK

How-To fix the VCRUNTIME140.DLL error

The VCRUNTIME140.DLL error seems all too common when mining on Windows 10 computers.  I recently came across it on a system that I manage.  I was trying to install, configure, and run XMR-STAK so we could mine LOKI with it and figured that if it is affecting me, it is probably affecting others.

So here is the fix….

Download and install the Microsoft Visual C++ Redistributable package from here :

https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

And you can now run and install XMR-STAK

Mining using AMD RX480 Nitro & RX580 Nitro on Ubuntu

How-To Guide for mining with the AMD Series cards on Ubuntu Server 16.04.04

This guide assumes you already have the Rig built, and Ubuntu Server 16.04.04 installed on it.  Once the rig boots to the terminal, this guide begins.  I am going to install everything as root, yes there are reasons why you should and should not do it that way.  I just prefer to get it up and running as quickly as possible.  I do not store anything on my miners, and you should not either.  Keep your wallets off your mining rig.  Keep your coins secure.  Keep your miners with limited data on them, so you can wipe and reinstall on the fly if you need.

Once Install Ubuntu 16.04 Server is installed type the following in bold as they appear

sudo bash

ifconfig

apt-get install openssh-server

Now you can use your laptop/desktop and log into the server.  Download putty, and connect to the server via it’s IP or Server Name.  My Username Name is tacticalware, so you can change everywhere you see tacticalware listed, you will change that to the username of the account you are logged in as

sudo bash

apt-get update

apt-get upgrade

apt install git screen nmap ncdu busybox inxi clinfo links unzip python xorg xserver-xorg-legacy xserver-xorg-video-dummy libcurl3

systemctl disable lightdm.service

mkdir /miner && mkdir /miner/drivers && mkdir /miner/drivers/amd && cd /miner/drivers/amd

Download the drivers from https://www.amd.com/en/support on a laptop

Now use Winscp on the laptop to copy the drivers to the Ubuntu Server

cd /home/tacticalware/ && cp ./* /miner/drivers/amd/ && cd /miner/drivers/amd/

The version I downloaded and used was amdgpu-pro-17.30-458935.tar.xz … you will need to change that part of the name to the version you have

tar -Jxvf amdgpu-pro-17.30-458935.tar.xz && cd amdgpu-pro-17.30-458935 && ./amdgpu-pro-install -y

usermod -a -G video $LOGNAME

Download the SDK from here to your laptop

Winscp it to the server

Move the SDK from your home directory to /miner/drivers/amd

tar xf AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2 && ./AMD-APP-SDK-v3.0.130.136-GA-linux64.sh

reboot

Log back into the server now

sudo bash

clinfo

clinfo | grep compute

nano /etc/X11/Xwrapper.config

delete the last line:
allowed_users=console

insert at end of file:

allowed_users=anybody

Save the file and exit

cd /miner/drivers/ && mkdir claymore && cd /miner/drivers/claymore

On your laptop download Claymore from

https://drive.google.com/drive/folders/0B69wv2iqszefdmJickl5MF9BOEE

Winscp it to the mining rig

Move it to /miner/drivers/claymore

tar zxvf the file

nano zec.sh

#!/bin/sh
xinit &

./zecminer64 -zpool us1-zcash.flypool.org:3333 -zwal t1QYSbLrnbECDu76KDcvoyjBbbhsuWxZXWm.miner20 -zpsw x

Save the file and exit

chmod +x zec.sh

Update config.txt file, also modify epool and dpool with your wallet info and remove default dev info

Save the files

screen ./zec.sh

Now you will want to watch for issues

You can close putty whenever, it does not need to be open for your miner to work, and if you want to reattach a screen, log back in using putty and type

screen -r

Installing TPRUVOT’s CCMiner on Ubuntu 16.04

How-to Guide for Installing the Linux version of ccminer (tpruvot) on Ubuntu 16.04.04

This is a quick guide that I created a few months back.  It gets the latest version of tpruvot’s ccminer installed and running on your Ubuntu mining rig.  There are a lot of algos which can use this, and since most of my rigs run on linux, I had to find a way to get it installed.  It is the general commands that I use from a terminal.  The assumption here is that you already have Ubuntu 16.04 installed and updated.  It is also assumed that you are running NVidia 1080Ti cards, and they are all functional.  I am going to run it all logged in as sudo to make it quick and easy.

From the terminal:

sudo bash

apt-get dist-upgade

apt-get purge nvidia*

reboot

mkdir /drivers && mkdir /drivers/nvidia

wget https://developer.nvidia.com/compute/cuda/9.1/Prod/local_installers/cuda_9.1.85_387.26_linux

mv cuda_9.1.85_387.26_linux cuda_9.1.85_387.26_linux.run

chmod +x cuda_9.1.85_387.26_linux cuda_9.1.85_387.26_linux.run

sh cuda_9.1.85_387.26_linux.run

Answer “yes” for installing the nvidia-drivers, the cuda tools and the symbolic link.

apt-get install git automake openssl libssl1.0.0 libssl-dev libcurl4-openssl-dev

cd /drivers/

git clone https://github.com/tpruvot/ccminer.git

cd ccminer

nano Makefile.am

cd /home/miner/ && nano .bashrc

add this to the end:
export LD_LIBRARY_PATH=/usr/local/cuda-9.1/lib64:$LD_LIBRARY_PATH
export PATH=/usr/local/cuda-9.1/bin:$PATH

CTRL & X

Y to save

nano start.sh

Insert the following into the file:

nvidia-smi -acp 0
nvidia-smi -pl 300
./ccminer -a x16r -i 20 -o stratum+tcp://us.bsod.pw:2176 -u RMzHAFgqgjV5qLkajBjLQ325V7HWBpG3d9 -p c=RVN

CTRL & X

Y to save

chmod +x start.sh

./start.sh

You are now up and mining.  I have chosen Raven for this one, only since I was mining it when I put it together.  You will want to remove my wallet address and insert your own.  Otherwise, the rest will get your rig up and running.

Happy Mining!

Mining LOKI on Windows 10 with NVidia 1080TI Cards

How-to Guide for Mining LOKI

Quick rundown on how to mine a new crypto named LOKI or LOK as some of you may know it as.  I mine it with both NVidia and AMD series cards.  This guide will walk you through mining it with NVidia Series cards.  You will find that the guide is a mirror of the AMD guide, except for how you fine tune it at the end.

The mining software will throw errors with your AV program.  You will need to whitelist the files when they are downloaded, or disable Realtime Protection..  Personally, I only use Windows Defender on my mining rigs, so I can keep the costs down, plus it is easy to wipe and reinstall the OS if need be.

For Windows Defender, you will need to open the program up, and disable Realtime Protection

If you are using Chrome as your Browser, you will also need to allow the download there as well.  To do this:

Open up Chrome

In your address bar type in chrome://settings and press Enter

Scroll to the bottom and select Advanced

De-Select “Protect your device from dangerous sites” 

Now you can download the software

Open up another chrome tab and download XMR-STAK to your Windows 10 computer from here:

https://github.com/fireice-uk/xmr-stak/releases

Once you have it downloaded, go ahead and unzip the file to your Desktop

Navigate to the unpacked files

Double click on xmr-stak and Run the file

You will need to insert a port for monitoring the progress.  I use port 30131 and press Enter

Next type in cryptonight_heavy and press Enter

For the pool address, I use loki.ingest.cryptoknight.cc:7733  press Enter

Your username will be your wallet address, for example

LChtjHqr29p5FojLdMtcUW5ApLWyQHH5j4366V78YECEjUkgK99Y7uLDVLpHjXpYM3UcZ39FFL5Gvd4debF95mcJHbnx5ke

Your password will be your worker name.  For example mine is Miner6

Your Rig Identifier can be empty, so just press Enter

Input N for TLS and press Enter

Insert N for Nicehash and press Enter

Input N for multiple pools and press Enter

Select Yes when prompted

and your miner will begin!

Now you can use the ipaddress:port/h of your miner to keep an eye on it’s progress from anywhere in the network.  For example, navigate to

Once you are mining, you can open up the nvidia.txt file in the same directory as your xmr-stak executable.  Within the nvidia.txt file, you will be able to modify your settings.  I have found that changing the threads setting it will yield the most results.  Each series of card can act differently, so spend some time, and fine tune this settings.  It will be worth the time invested.

Happy Mining!

Burning the Ubuntu Server 16.04.04 ISO onto a USB

Step One – Prepare the OS Installation Media

Below you will find the default way in which I use a Windows 10 Computer, Etcher, and a USB Drive, to create and install Ubuntu Server 16.04.04 onto a mining rig.  Once you have that ISO flashed onto a USB drive, you can go from mining rig to mining rig, installing the Operating System.  So this really is step one in the entire process.  This guide will in turn become the starting point for each linux based coin/token/masternode that we will gather.  Shoot me any questions you have.

From your Windows 10 machine, Download and install the Bittorrent Client:

http://www.bittorrent.com/downloads/complete/track/stable/os/win

 

Then download the Official Ubuntu Server 16.04.04 (x64) Release:

Finally, Download and Install Etcher (this will write your ISO to the USB Drive)

https://etcher.io/

Once the Ubuntu software has been downloaded, insert a USB drive to write the Operating System Installer to

Make sure this USB drive has nothing else on it.   Everything will be erased

To write Ubuntu to the USB drive:

Open Etcher

Click Select Image

Navigate to where you downloaded the Ubuntu ISO (it is probably located in your Downloads folder)

Select the ubuntu-16.04.4-server-amd64 image and click Open

Click Select Drive

Select the USB drive

Click Continue

Click Flash

Select Continue to Flash the drive

It should take a few minutes for Ubuntu Server to be written to the USB drive

When it has completed flashing the USB drive you can click the X at the top right corner to close the window

Now, you are ready to begin the installation.  So, insert it into a USB 3.0 port on your mining rig, and turn the rig on

 

My Setup – Ubuntu Mining Rig with NVidia 1080Ti cards

Rig Parts Breakdown and Driver Installation for the NVidia 1080 TI GPUs on Ubuntu 16.04.04

I have several rigs running at any given time. Below you will find the equipment list for my NVidia 1080 TI Rigs, and also the installation instructions on getting the Drivers working under Ubuntu 16.04.04

Rack to Install the Hardware On.  I usually put two full rigs onto one single rack.  It saves space and I end up stacking mine (QTY 1): Seville Classics 3-Tier UltraZinc Cabinet Organizer, 7.5″ W x 17.5″ D x 18.5″ H

These steps will help you install the drivers.  It assumes that you have the hardware connected and Ubuntu Server 16.04 already installed.

Log into your Rig

Open a Terminal

sudo bash

apt-get update && apt-get upgrade

apt-get install gcc libglu1-mesa libxi-dev libxmu-dev libglu1-mesa-dev screen

lspci | grep -i nvidia

Check to see if all gpus are listed

apt-get install linux-headers-$(uname -r)

mkdir /miner && mkdir /miner/drivers/ &&  mkdir /miner/drivers/nvidia && cd /miner/drivers/nvidia

sudo add-apt-repository ppa:graphics-drivers/ppa && sudo apt update 

wget https://developer.nvidia.com/compute/cuda/9.1/Prod/local_installers/cuda_9.1.85_387.26_linux

chmod +x cuda_9.1.85_387.26_linux

mv cuda_9.1.85_387.26_linux cuda_9.1.85_387.26_linux.run

apt-get purge nvidia*

screen sh cuda_9.1.85_387.26_linux.run

Answer “yes” for installing the nvidia-drivers, the cuda tools and the symbolic link.

nano /etc/ld.so.conf.d/cuda-9.1-x86_64

put only one line:
/usr/local/cuda-9.1/lib64

Save the file and exit

Then run

ldconfig

In the next step you will want to change tacticalware to the name of your home directory

cd /home/tacticalware/ && nano .bashrc

add this to the end:
# add cuda tools to command path
export LD_LIBRARY_PATH=/usr/local/cuda-9.1/lib64:$LD_LIBRARY_PATH
export PATH=/usr/local/cuda-9.1/bin:$PATH

Save the file and exit

systemctl disable lightdm.service

reboot

Log back in and check to ensure all of your GPUs are still accessible

nvidia-smi

That’s it.  Your GPUs are setup and ready to mine!
