I think I will end this guide at this point for now as it is getting to be quite long. While I originally intended to cover fine tuning and going over other optional arguments that the EWBF miner can use, I think I will wait and make this a two part guide. For now this Part 1 covers the basic setup and configuration of getting the EWBF miner running and shares being submitted to a pool. Since it will usually take some time before reaching a pools minimal payout period anyway, especially for just one or two cards, we have some time.
While not mandatory, it is recommend to install a GPU overclocking utility such as Afterburner to be able to optimize your GPU settings to mine the most efficiently. The installation of MSI Afterburner is straight-forward and should not require a reboot. For the EWBF miner there is nothing to install as we will be simply extracting the programs folder and running the program’s exe. We will however need to modify one of the example batch files included with the miner in order to get started.
In this post I’ll break down the various steps required to mine the eagerly anticipated Zcash which is due to be released on the 28/10/16. In advance of the launch day we can prepare our machines to be ready right from the very start.
Keep in mind that Equihash makes CPU mining still somewhat feasible for Zcash. However, you’ll mostly receive a better RoI with GPU investments, so consider the options above first before exploring your CPU options.

For those with inexpensive power, this is not an issue. For those with expensive power, it can be the largest recurring cost for Zcash mining. Using our power consumption and hash rate data, here is what profit per day looks like with $0.10/ kWh, $0.20/ kWh and $0.40/ kWh power:
Next, you’ll want to modify your system page file and manually set it to 16384 MB (16GB). Right click “This PC” from Windows Explorer and choose “Properties”. Click on “Advanced system settings”. On the Advanced tab, click “Settings” (under Performance).
We also recorded power consumption during our testing both before mining, then after adding the GPU and having it mine for 60-72 hours. Here is what an average power consumption, per card, was for the final 12 hours of our observation period when the cards were thoroughly heat soaked:
Replace “eu” for your location, “ZEC-ADDRESS” for your zcash wallet address (transparent address), replace “-t 8” for the number of threads you want to use, and lastly replace “-og 0” for the number of GPUs you’re using (as in -og 0 1 2 if you’re using 3 GPUs)
Currently the NiceHash EQM Zcash miner is the fastest ZEC miner out there for Nvidia GPUs with the latest release bringing up to almost 50% increase in performance for most Nvidia GPUs. Everything would have been perfect if you could use the miner for other Zcash pools, but the EQM miner is still only supporting the NiceHash service, so you cannot mine ZEC with it, just sell your Zcash hashrate and get paid for it in Bitcoin. The recently released EWBF CUDA Zcash Miner is probably the fastest ZEC miner for Nvidia GPUs that is available for Windows that you can use on other pools for mining Zcash directly, though it is slower than the latest EQM miner release and that one also comes with 2% dev fee (no fee on the NiceHash miner, but only locked to their service).
Zcash is an open source cryptocurrency that focuses on the privacy element. This cryptocurrency is mineable utilizing the CPU, and/or GPU. It is a popular currency to mine with nVidia GPU’s as the algorithm hashes better on these GPU’s vs. their AMD competitors. The GTX series is the most popular for mining Zcash.
I’ve had success both ways, so if you run into an issue with one method, delete the drivers and try the other method. If you need to remove your drivers, use the DDU (Display Driver Uninstaller) program from Guru3d.com to remove everything cleanly, then start over.
If you have a Linux CUDA compute machine available we highly recommend using nvidia-docker. Installing different CUDA versions for Zcash mining and deep learning frameworks and managing versions can be painful. Using nvidia-docker you do not have to worry about that.
The miner still needs some work, especially on Nvidia GPUs where by default it is pretty heavy on the CPU load and memory usage as well. It is recommended that Nvidia users add the parameter –enable-nv-hotfix in order to reduce the CPU load a bit, but still running the miner on the main GPU may make the system a bit unresponsive even with that parameter. Still if you are interested in mining MNX (even with the high hashrate and low block reward at the moment) or any other Equihash 96/5 coin you might want to check the lolMiner-mnx out.
–server us1-zcash.flypool.org (the — indicates a parameter with a valid keyword will follow, in this case server. Then a space and the variable for the parameter, in this case the flypool server address.)
6. It is recommended that you install applications such as MSI Afterburner in order to control the card’s fan. In its default mode, the power is low and it allows the card to reach a temperature of 70-80 degrees Celcius (normal when playing occasionally but not healthy when it comes to a machine running 24-hours a day).
Another cloud mining service provider that has been available for quite some time already as well – HashFlare has also announced their plans for offering cloud mining hashrate for Zcash (ZEC). They have already started the presale of mining contracts with a price of 4.20 USD per 0.1 H/s with the launch of mining planned to start before 21.11.16, so you will be able to catch some of the slow start mining period as well. Each of their Zcash cloud mining contracts will last for 1 year (from activation) and will not have any additional fees as everything is apparently included in the price.
As you can see our current Hashrate is showing as 506.7 H/s, which is equivalent to the Sol/s reading on the miner. The avergae hashrate is showing as 494.6 and is the effective rate for the past 24 hours. I should point out that this rate is slightly lower than the average mainly as I shut this miner down a few times in the course of writing this guide. The final part are the valid and invalid shares. Obviously you want as near as 100% valid and 0% invalid as possible, but don’t be too concerned if your see 1 0r 2% in the invalid column on occasion.

The average mining rate of the system is 200Mh/s, providing an opportunity for an excellent return at current ETH values, if ETH continues to climb as Bitcoin has it will produce a return many times over.
Besides the ability to rent and lease hashrate for the new Equihash mining algorithm being used by Zcash (ZEC) NiceHash is also offering what they call Fast Zcash Cloud Mining Contracts. These are 24 hour mining contracts, but with a large amount of hashrate that you are getting for this short period of time. This is an interesting alternative to long term cloud mining contracts, but probably not the best one for the moment while we are still in the slow start of mining for Zcash. Still a nice alternative to have to long term contracts as well as to traditional renting of hashrate where the price may vary and here you have a fixed price for the day.
Some settings should be modified in Windows to get you ready for mining. First, you don’t want your computer to go into Sleep mode, as it will interrupt your mining. Go to your Power Settings and set Turn Off/Sleep to Never.
Troubleshooting tip: Some miners have had success installing all GPUs at once, then installing the drivers. Others prefer to install only one card, install the drivers, shut down the system, and then install the rest of the GPUs.
To see all the directories in your current location type ‘ls’. I personally like to change the name of my zcash directory in the home folder to ‘zcash’ just so it’s shorter. You can do this by selecting the directory you want to rename and pressing ‘F2’. Now we will need to change directories to the zcash directory. So type in the terminal
Zcash also differs because it has a built-in privacy protocol called zk-SNARKS, which is designed to make it the leading privacy-based crypto in the market (competing with other privacy coins such as Dash and Monero).
Zcash mining is very simple and it is good news for beginners now they need not to download full Zcash block chain. They need not to manage clunky command line miners with manual instructions. If you are a beginner you can go for Zcash mining directly.

Both brands of GPU can be good at mining Zcash depending on the model. It will take some research to find what the Cost/Performance/Electricity consumption trade-offs are. Here a list of places to start:
On the GPU side, we are going to use the Claymore miner. Claymore has a long-standing reputation for optimizing miners and this miner speaks for it. It improves the hashing rate considerably and that is why we are going to take the time to download and use this miner as well. The genoil miner only works for pool mining and with AMD graphic cards. This miner charges a 2.5% developer fee. Every hour the miner mines for the developer during 90 seconds. However, the performance increase is well worth the fee charged. If you don’t agree with the dev feem, don’t use this miner
This is a list of the most popular Zcash Mining software for each platform, some of this software contains a built-in developers fee. I try to keep this list up to date as I can, if there is a broken link or missing software please drop me an email.

Notice I only have one GPU running. If you have multiple GPUs they all should be displayed as separate line entries starting with 0. At the top we can verify the mining program and version, the server, solver we are using (in this case the default or auto selected), devices configured for mining (more for multiple GPU systems, in our example just one even though it says all), max temperature limit of 90 degrees C (default setting) after which point the mining software will shutdown to prevent GPU damage, and information on if the optional API is enabled or disabled, as in our case.
We’ve been using Nanopool for our ETH mining rigs for over 4 months, and it works just fine. Dashboard is very clear and makes it easy for newbies like us to setup. Payments are released once or twice a day when every time we reach our ETH threshold. So far, no caomplaints whatsoever. Plus, they send you email notifications every time a rig stops mining for any reason.
