1. CPU


CPU stands for ‘central processing unit’ and is a key part of a computer. The CPU tells the other parts of the computer what to do according to any installed software (SW). When a SW is installed, the CPU therefore dictates the conditions, as directed by the SW, for the computer to perform what is scripted. The CPU reads all SW installed in the computer, which means that the power of the computer is shared between the open and used applications at any given time. To exemplify what this means: if the computer needs to perform instructions from two different SW programs at the same time, the power of the processor needs to be shared between the SW programs and none of them can utilize full power of the computer. If you mine and work with the computer simultaneously, the power is therefore shared between the mining and the other things you perform with the computer.

An example of a function of the CPU is: if you save a document, the CPU needs to turn the document into the appropriate file type and direct the hard drive to write it as a file. Of course, the CPU is designed to do several things, but in summary it should be able to switch between different tasks on a moment’s notice.

2. CPU Mining

Mining with the CPU means it utilizes the power of the processor to perform the mining. The CPU reads the mining SW and instruct the computer to mine accordingly. The CPU sits under a heat sink, which usually is a fan, or sometimes cooling is made with water. The cooling system is necessary to prevent overheating the computer. CPU can definitely be used for mining, but it is not the most optimal way to mine. A couple of reasons being: the CPU is not constructed for repetitive tasks, which mining contains of; there are risks for overheating without a sufficient cooling system; and since the CPU is the executive of the computer, it is used for other tasks as well. This, with other reasons, is why the output of CPU mining is not as high as with GPU. With a fairly new, standard computer you can mine on the CPU, but be aware of the h/s (hashes/second), if they average 40-50 h/s you need to perform some kind of upgrade of your hardware.

3. GPU


GPU stands for ‘graphics processing unit’ and is part of the video interpretation system of a computer. The normal use of the GPU is to assist the interpretation of 3D graphics and visual effects so that the CPU does not have to. Most mainstream computers have much slower, but less power consuming and cheaper, IGP’s (integrated graphics processor), which also are GPU’s but integrated directly into the chipset in the computer. A separate more powerful GPU is normally needed for graphic intensive tasks such as gaming or mining.

A GPU can also do the things the CPU can, but the design of the GPU is specialized on video processing, which by default means a lot of repetitive work, since it is constantly being told to do the same thing to a large number of pixels on the screen. In order to make this run efficiently, video processors are far better on the ability to do repetitive work, compared to the ability to rapidly switch tasks as the CPU does.

4. GPU Mining

Mining with the GPU means it utilizes the power of the graphic card to perform the mining. Due to the design of the GPU, it is far better to use for mining than CPU. The GPU design, to manage repetitive tasks, is optimal for mining. With a GPU, a lot more power can be used and it goes faster. As a result of this the output of the GPU mining is higher compared to the CPU mining. Computers with several graphic cards naturally have even higher power and capacity, which in turn generates a higher output of the mining. Gaming computers have graphic cards from the beginning, see below examples on graphic cards that is good to use for the mining. Note that the result is dependent on what graphic card you have, see below minimum requirements.

5. Difference between CPU and GPU Mining


A GPU is like a CPU, but with internal differences that make them better suited towards their special tasks. These differences make mining far more favourable on a GPU instead of a CPU. Using a GPU for mining give a much higher output, approximately 5-10 times higher output, compared to using CPU.

A CPU gives instructions to the computer, based on how the SW is written, and therefore has the ability to rapidly switch tasks. A GPU can do this as well, but is designed to do video processing, which requires a lot of repetitive work. In order to make this run efficiently, the GPU is built for this purpose and are therefore far better in doing repetitive work i.e. here read mining.

GPU's have large numbers of ALU's (arithmetic logic unit), which is a calculation unit that performs logical conditions such as ‘AND’ and ‘OR’ as well as arithmetic calculations such as ‘addition’ and ‘subtraction’. Due to the large number of ALU’s in GPU’s they can do a large number of mathematical labour in a greater quantity than CPU's, which is required for mining.

You can run both CPU and GPU at the same time, even if CPU delivers less it will mine on both.

6. Minimum requirements for mining in eXeR GPU mining

- Graphic cards older than 3 years shall not be used, they are simply to old

- A graphic card shall have a minimum 2 GB memory to be able to mine properly

- Minimum Windows 7

- Latest JAVA has to be installed on the computer

- Latest drivers installed for NVIDIA and AMD

- NVIDIA graphic cards that are compatible with the mining and good to use are:

- GTX1050ti, GTX1060-3GB, GTX1060-6GB, GTX1070-8GB, GTX1070ti-8GB, GTX1080-8GB, GTX1080ti-11GB and TITAN X-12GB

- GTX series 700, 800 and 900 works as well. Those are less efficient than the ones above, but they are supported by the mining SW. If you have a graphic card in any of these series, try it out, if it does not work issue a request to the support (see below on point 10). They will make modifications to get it started, if it for any reason does not work, you will be notified.

- Series GTX500 – 600 cost more in power than they generate and are not supported by the mining SW.

- AMD graphic cards that are compatible with the mining and good to use are:

- RX460, RX470, RX480, RX560, RX570, RX580, RXVega54, RXVega64 and Vega Frontier Edition

- Some graphic cards cannot be used, if you start and realize it does not work you should contact the support (see below on point 10) and get reviewed why and if it is possible to solve.

- The mining SW can mine both CPU and GPU at the same time, as long as you have a compatible graphic card in your computer. You simply select one of them or both when starting the mining.

7. Comparison between CPU and GPU Mining output

Note! This is an example only!!

If a CPU in average makes approximately 120 h/s (hashes per second) it can be compared to a GTX1050 graphic card that will perform 300 h/s on CryptoNight algorithm for Monero coins.

Use the example as an illustration of the large difference in output of CPU vs GPU mining.

See the difference in h/s with different graphic cards:

GTX1060 18-20 Mh/s - Ethereum

GTX1070 25-27 Mh/s - Ethereum

GTX1080Ti 30-32 Mh/s - Ethereum

8. Installation of mining software


- If you have not installed the software before you will find the installation guide at the start page when you enter the mining page!

- If you have installed the software before, you will find the installation guide under the menu ‘About’ on the mining page!

- Follow the installation guide step by step and you shall not have any problems!

- If you have installed a previous version of the mining software start with uninstalling the current version!

- De-activate the anti-virus system temporarily (the software is without malware and does no harm to your computer, but it removes a necessary file that result in that the installation fails)! All computers have a function that de-activates the online scanning of viruses for a set time, like 15-30 minutes.

- Install the mining software.

- Activate the anti-virus again, unless it is done automatically by your computer.

9. After you have installed the mining software


- Decide if want to run both CPU or GPU after installation. Select one of them or both.

- New features are temperature of the mining and selection of capacity (from computer vs graphic card) to use when mining, se info below.


When you enter the start page of the mining, you will find a display of the temperature of the mining. Read below BEFORE you start! When you have started the mining, make sure to monitor the temperature according to below and adjust if necessary.

Settings CPU:

- Set 25% Low performance if TOTAL CPU usage is 50% or over BEFORE start mining

- Set 50% Middle performance if TOTAL CPU usage is 40% or over BEFORE start mining

- Set 75% High performance if possible BUT watch out to make sure that the percentage does not rise above 90%!

- Set Smart: Program adjusts itself for highest performance and still allow you to use other programs, BUT watch out to make sure that the percentage does not rise above 90%!

Settings GPU:

- Set 25% Low performance, use this if you play games while mining

- Set 50% Middle performance, use this if 75% shows to be to hot and noisy for your GPU

- Set 75% High performance when possible, BUT watch out to make sure that the temperature does not rise above 80% degrees!

- Set Smart: Program adjusts itself for highest performance and still allow you to use other programs, BUT watch out to make sure that the temperature does not rise above 90% degrees!



Note that temperature for AMD cards cannot be shown in the miner software, so be sure to monitor from time to time. Normally computers close down automatically if there is a risk of overheating.

10. eXeR Mining is based on the NETWORK


It is VERY IMPORTANT to understand that eXeR mining is built to suit mining in a network and the commission system is set-up in such a way that you earn more the bigger your network is (maximum 5 levels down in the network). Nobody will make a fortune in eXeR mining by themselves, it is required to grow the network of miners to earn a high commission! With a big network a miner in eXeR can earn 100.000 € and above per month! You by yourself sets the limits to what you can achieve by growing your network to the size that suits you and that meets your goals!

A single miner can with other mining systems earn higher commission than one single person, in eXeR, mining by him/herself, BUT nobody can earn as much, in a mining network, as they can with eXeR mining with a big network, due to the generous commissions paid back to the network!
