Gravium is a new coin that uses the x16R algorithm. The coin was designed to be an ASIC-resistant cryptocurrency. ASICs are specialized hardware that can extract a specific algorithm faster than the GPU extraction and are also much more efficient. The main argument against ASIC is that it creates a decentralized mining experience, since ASICs are more expensive and more difficult to obtain than a GPU or CPU.
The x16R algorithm is unique because it uses 16 different algorithms randomly selected based on the hash of the last block. For this reason, the order is always random, making it very difficult to create an ASIC for. This unique algorithm is one of the reasons why the Raven coins and other x16R algorithms have grown in popularity.
Some unique things about gravium are that they include masternodes and an instant send function. I like the fact that they also have a one-click miner and an easy GUI masternode configuration tool in 3 steps.
Now that we know the details of Gravium, we get to GRV mining!
Some general tips for mining
So, before starting this tutorial, I have two suggestions to make the most of your mining experience. First make sure you have the latest drivers for your GPUs. Secondly, most mining software will be flagged as virus by virus scanners. For this reason, if you perform mining operations on your normal gaming or everyday computer with an antivirus installed, it is advisable to exclude the mining software from the antivirus. What I like to do is create a folder and then insert all my mining software into subfolders. Then I exclude the top-level folder from the antivirus and this excludes all the mining software.
Mineral pools
The first thing we need is a mining pool. You can mine mine, but the payments could take months, depending on how powerful your mining rig is, and the mineral pools usually require a very small fee (1% or less). Using a pool will allow you to receive consistent payments, several times a day.
For this tutorial we will use https://blockcruncher.com/. I chose this pool because it has low rates (0.25%) and good features. As for their features, there is a small pool, with some x16r and x16s coins to choose from.
Now that we have a pool, let's start the extraction!
CPU extraction
We will not focus on CPU mining as it is not profitable, compared to GPU extraction.
GPU Mining: Nvidia
For GPU mining there are many programs for Nvidia, but what I found better is CCminer. The miner does not have a Dev commission. This data mining software is compatible with Windows and Linux, however only precompiled binaries for Windows are available.
You can find the official page and the download link at the address https://github.com/tpruvot/ccminer/releases
Once downloaded, it's really simple to use.
Just create a new batch file (or a script file if you use Linux) inside the folder where the miner is located and paste it into the batch file
ccminer-x64.exe -a algorithm -o stratum + tcp: //mining_pool: port -u wallet_public_key -p c =coin_symbol
Replace "algorithm" with the algorithm you want to use. In this case we have to use "x16r"
Replace "mining_pool" with blockcruncher.com
Replace "door" with 3434
Replace "wallet_public_key" with the address of your wallet.
Replace "coin_symbol" with GRV
For example, my configuration is:
ccminer-x64.exe -a x16r -o layer + tcp: //blockcruncher.com: 3434 -u GN8gxb4Zd8qTqKnQeVmuTdYqszG6r9Bdo5 -p c = GRV
Double-click on the batch file to run the miner and you should see something similar
The red arrow indicates the detected GPU and the total speed.
The blue arrow indicates the clock speed of the GPU, hash per watt, total power consumption, temperature and fan speed.
GPU Mining – AMD
For GPU mining there are many programs for AMD, but what I found to be the best is sgminer-gm-x16r. The mining software is compatible with the Windows and Linux operating system. Data mining software has no development costs. This data mining software is compatible with Windows and Linux, however only precompiled binaries for Windows are available.
You can find the official page and the download link at the address https://github.com/aceneun/sgminer-gm-x16r/releases
Once downloaded, it's really simple to use.
Just create a new batch file (or a script file if you use Linux) inside the folder where the miner is located and paste it into the batch file
sgminer -k algorithm -o stratum + tcp: //mining_pool: port -u wallet_public_key -p c =coin_symbol
Replace "algorithm" with the algorithm you want to use. In this case we have to use "x16r"
Replace "mining_pool" with blockcruncher.com
Replace "door" with 3434
Replace "wallet_public_key" with the address of your wallet.
Replace "coin_symbol" with GRV
For example, my configuration is:
sgminer -k x16r -or stratum + tcp: //blockcruncher.com: 3434 -u GN8gxb4Zd8qTqKnQeVmuTdYqszG6r9Bdo5 -p c = GRV
Double-click on the batch file to run the miner and you should see something similar
The red box indicates the total speed for all the combined GPUs.
The blue box indicates the temperature, the fan speed and the total speed of each GPU.
If there are problems it may not have enough virtual memory. You may need 16 GB of virtual memory (for Vega GPUs you need more than 16 GB per GPU) to change it go to Control Panel -> System and Security -> System and click on Advanced System Settings on the left. From there, click Settings on the Advanced tab. After clicking edit, then on the third screen, deselect the automatic management, choose the custom size and type the size (in MB) for both text boxes. Then press the set button, then the ok button.
Solving general problems
One thing to monitor is stale or rejected shares. If you see a lot of expired shares, you may want to try a server closer to you. If you see a lot of rejected actions, try to reduce the miner's intensity, if available.
How much GRV will I earn per day?
To figure it out, you would go to http://whattomine.com and use the calculator. The calculator provides a rough estimate, so you may receive a sum higher or lower than the one actually indicated by the calculator. The Gravium coin calculator is located at https://whattomine.com/coins/262-grv-x16r
Most of the values are already entered correctly and you only have to change some values.
Hash rateEnter your total speed (in megascosto per second) for all your mining computers. This would be the value of "total speed" in your data mining software. Be sure to add all the computers you use for Gravium extraction.
Power: Enter the total amount of power (in watts) used by your rig. Some mining software will measure it for you. You can also measure the total energy consumption for your computer using special software or a kilowatt meter. I prefer to use a kilowatt meter, because I find it to be the most accurate. Be sure to add all the computers you use for Gravium extraction.
Cost: Enter the cost per kilowatt hour you pay to the power company. I was able to find this information on my monthly bill, as well as on their website.
Pool rate: Enter the pool rate + the mining software development fee. For our example, you would enter 0.25 + 0 = 0.25
Hardware cost: Enter the total cost of all your hardware.
Using my AMD Vega system for an example, I'll show you how to read the data. In the image above there are really 3 things I'm looking for.
# 1 Look at the Difficulty 24 hours and the Difficulty 7 days. We want them to be all the same, what they are. This tells us that the calculations that we will see in the second image below, will be precise for the days to come, provided the price is not volatile.
# 2 Look at the FORMER. 24 hours volume and the Market Cap. Generally, the bigger these are, the less the price will be volatile. We want the price to be non-volatile, so our calculations will be accurate for the days to come. In this example, the market capitalization is small, so the price may change a little from day to day.
# 3 Look at the Create 1 BTC in and the Break even in. It is always interesting to see how long it will take your rig to create 1 BTC. The break even in, will show you a rough estimate of how long it would take to pay for your mining rig, extracting this particular coin. This is great to use before building your mining rig, to see how long it will take before you see the profits.
In this image, we can quickly see how many coins and value in USD we will make in certain periods of time. You want to see the Profit column, as this is the value after paying for your electricity consumption. I usually focus only on the daily payment in USD. By focusing only on this number, you can run the calculator for a few different currencies and quickly see which currency is most profitable for setting up the mining platform. Keep in mind that you also want to weigh the daily payment with the market capitalization. A low capitalization coin could be really profitable one day, so it could have half the payment tomorrow.
That's all. Now you should do Gravium mining! Be sure to type your public key in the mining pool control panel to keep track of your statistics.
