Philip Deidesheimer was a mining engineer in the Western United States.
Set Mining in Tournaments. Set mining in tournaments is an art in and of itself. You are going to have scenarios where set mining is right and profitable, but there will also be endless spots where the numbers won’t justify moving forward. It’s often stated that poker. When you start up your ethereum node with geth it is not mining by default. To start it in mining mode, you use the -mine command-line flag. The -miner.threads parameter can be used to set the number parallel mining threads (defaulting to the total number of processor cores). Geth -mine -miner.threads=4.

While it might sound completely anti-business to restrict part of its market share from its hardware, Nvidia is playing the long-game when it comes to crypto mining hardware. Square set timbering. Deidesheimer invented a system, now known as square set timbering, using heavy timber 'cubes' as supports for underground mining tunnels and shafts, that enabled skilled miners to open three-dimensional cavities of any size. In large openings, the cubes could be filled with waste rock, creating a solid pillar of wood and rock from floor to roof ('back' in miner's terminology).
Deidesheimer was born in Darmstadt, Hesse, in 1832 before German unification. He attended the prestigious Freiberg University of Mining (Technische Universität Bergakademie Freiberg) and emigrated to California in 1852. He died on 21 July 1916 in San Francisco, California.
Career[edit]
In 1852, at nineteen, the young mining engineer traveled to the California gold fields to work for several years, including in Georgetown. In April 1860 he was hired by W. F. Babcock, a trustee of the Ophir Mine, part of the Comstock Lode silver mining boom in Nevada, and solved one of the Comstock mines' most critical engineering needs.[1]

Square set timbering[edit]
Deidesheimer invented a system, now known as square set timbering, using heavy timber 'cubes' as supports for underground mining tunnels and shafts, that enabled skilled miners to open three-dimensional cavities of any size. In large openings, the cubes could be filled with waste rock, creating a solid pillar of wood and rock from floor to roof ('back' in miner's terminology).[2]
Deidesheimer created the square set timbering system for the Comstock Lode's Ophir Mine in Virginia City, Nevada, in 1860.[3] The system, which was inspired by the structure of honeycombs, enabled mining of the large silver orebodies of the Comstock Lode, which were in very weak rock—in miner's terms, 'heavy ground'.
Deidesheimer refused to patent the innovation,[4][5] which was easily the most important mining innovation of 1860.[2]
- Ophir Mine
As was common with the Comstock mines, the rock in the Ophir Mine was soft and easily collapsed into the working stopes (cavities where ore is extracted). In addition, the presence of clay that would swell greatly upon exposure to air caused great pressures that the mine timbering of that day could not hold back. The square set timbering method devised by Deideshimer slowed the swelling action long enough for ore extraction, though with time and decay the timbering was crushed by the enormous pressures found in the Comstock mines.
Deidesheimer was made superintendent of the Ophir Mine by mine owner William Sharon in early 1875. He was bankrupted by speculation in mining stocks in 1878.[3]
Other mines[edit]
In 1866 Deidesheimer designed and supervised the construction of the Hope Mill and smelter for the St. Louis and Montana Mining Company, to process silver ore from nearby mines in Granite County, Montana.[6] The town that formed around the Hope Mill was named Philipsburg, in honor of Philip Deidesheimer.[7]
After the decline of the Comstock mines in the late 1870s, Deideshimer continued his successful mining engineer career at the Young America Mine in Sierra City, California, where he was one of the five mine owners made rich over the five years of good production at that mine.[3]
In media[edit]
The development of his square-set timbering method was fictionalized in 'The Philip Deidesheimer Story', a 1959 first-season episode of the American television series Bonanza, in which John Beal portrayed the title character.[8] Philip Deidesheimer was the subject of the NPR radio program The Engines of Our Ingenuity in episode 1901[9] and was inducted into the (USA) National Mining Hall of Fame.[10]

Msi Afterburner is designed to manage Nvidia and AMD graphics cards. Its main features are as follows: controlling the frequency of the graphics processor and memory, changing the voltage, adjusting the coolers of the video card, taking data on the state of the video card from the sensors and displaying them on the screen.
Also a program initially focused ongamers, allows you to record video and take screenshots. Software is indispensable for the miner, with its help it is easy to optimize video cards for long work with minimal wear and power consumption or disperse them to get maximum returns in a short time.
The program allows you to manage a group of video cards, and save up to five different profiles with settings. Software is free.
In this review, we will tell you where it is best to download, and how to properly configure the MSI Afterburner program for cryptocurrency mining.
Download from the official site
The name afterburner translates as 'afterburnercamera'. With it, you can squeeze maximum productivity out of your video cards. In order not to catch any attack on your PC, you need to download the msi afterburner from the official developers site https://ru.msi.com/page/afterburner.
</p>There are three versions of the program:
- Msi afterburner for Windows
- Android version for configuring a video card using a smartphone.
- MSI Afterburner Remote Server.
If you have a farm of several graphicadapters then msi afterburner configuration will be performed on the computer. Download the archive, unzip it to a folder convenient for you, and proceed with installing the program.
Install MSI Afterburner
</p>Open the folder with the latest version of the utility, onthe moment of the review is 4.6.2, and click on the Setup.exe icon to launch the installation file. You will be prompted to select the installer components. Configuring msi afterburner for mining does not depend on RivaTuner Statistics Server.
This is an additional utility that providessupport for frame rate monitoring, real-time video capture and statistics on the use of 3D acceleration. It is only needed for gamers and can negatively affect the performance of the rig. Uncheck the box next to RivaTuner and click 'Next.' Wait for the installation to complete and run msi af.
How to overclock a MSI Afterburner graphics card?
Using the AF application, you can adjust:
- The memory and core frequencies.
- Cooler rotation speed.
- Power consumption limit.
- Core voltage.
After installation, open the program as administrator, and make sure that it correctly displays all the video cards in Riga.
Set Mining Not Profitable
</p>By default, the panel will display the parameters of the first graphics accelerator. If all the cards are the same model, you can not configure msi afterburner overclocking for each of them individually.
The settings of the first map will be applied toto the rest. But, if you want to separately set the frequencies of each device, click the button with the gear logo on the left under the Fan Speed dial to open the settings menu, and uncheck the “Synchronize settings of identical GPs'.
</p>In the same window, unlock control is availablevoltage and expansion of acceleration parameters. In order to avoid malfunctions, the latter option is not recommended when setting up mining farms assembled from radically different models of video cards. Now let's proceed to the settings of msi afterburner for mining. We start with Core Clock and Memory Clock.
Important! Parameters need to be changed gradually no morethan 5-10 points. A sharp change in the frequency of the memory and the kernel will lead to a freeze, a reboot of the driver crash, and, possibly, to a breakdown of the video card itself.
The easiest way is to pre-searchparameters recommended for this GP model on thematic forums and set them before launch. If the result does not suit you, or you do not find the information you need, select the frequencies yourself. Just keep in mind that memory from different manufacturers, such as Hynix or Samsung, can be installed on the same model, and then the overclocking options will be slightly different.
Increase memory frequency
</p>This indicator is set on the Memory Clock scale. There are two ways to adjust.
- Move the slider manually using the mouse.
- Click on the number at the end of the scale and writedesired parameter using the keyboard. Then press Enter and apply the set value by clicking the checkmark button in the AF interface. It is located on the right under the cooler settings scale.
The core frequency is adjusted in the same way. And one more nuance. When setting the memory and core frequencies for AMD video cards, you simply write the desired values on each scale, for example 2100, 1100. Nvidia’s situation is slightly different, here you add (or decrease) the necessary number of steps to the factory parameters, e.g. +150, +30.
</p>But, it is not enough to find the maximum values at which the farm will work stably. Profit depends on energy consumption, and it must be reduced.
Reduce power consumption
</p>AMD Rx 5700XT graphics card according toWhatToMine calculator consumes 140W in mining, but by setting the core voltage to 860mV, you can reduce consumption to 115W. To do this, unlock the parameter control core voltage in the settings and gradually reduce the voltage, observing the stability of the device.
This option may not be available on someGP models, in this case, you need to use alternative methods. For example, modify Bios, or write the necessary parameters in the batch file of the miner program. This feature is provided by the latest versions of Claymore and Phoenix.
</p>On the left, next to the Core Clock scale, there is a button for regulating voltage parameters depending on the core frequency. In the jargon of miners, this option is called “kurva”.
Important! The graphic adapter does notshould work under load, and the parameters of the core frequency must be set to zero. After that, click on the shortcut in the form of a step and a window with two curves will open in front of you.
</p>Set the ratio of Core voltage to Core Clock, close the window and save the settings. After that, put on msi af the working value of the core frequency and start setting up the cooler.
We optimize the cooling system
</p>Scale power limit designed to set the limit of consumedpower. The default is 0 (100%). If the video card is overheating, try decreasing the limit, for example, to -20, and if it gives little stock or the core frequency constantly skips, add a limit, for example, to +20. If the card works at a low voltage, an increase in the power limit will not affect energy consumption, but a decrease can lead to a loss of hashrate and a decrease in the number of shares.
Important! By changing the limit of power consumption, you changethe value of the maximum allowable temperature of the GP. Of course, it cannot be higher than the threshold specified in Bios, but this is a rather high value. And, if, for example, your fan fails, the card will overheat. To allow this, write down the –tmax and –tstop parameters in the miner’s batch file, and if the utility does not have such options, follow the rig parameters using the msi afterburner mobile application.
Now go to the item msi afterburnercooler setting. The fan speed is set on the Fan Speed scale. By default, the driver automatically adjusts the speed. You can set the cooler speed in manual mode.
- Click the Auto button at the end of the scale.
- Set the desired rotation speed.
- Save the settings.
You can set the automatic operation mode in the “Cooler” tab of the settings menu.
- Check the box next to 'Set software custom auto mode.'
- Adjust the cooler speed curve in relation to the GP temperature by moving the control markers.
Keep in mind that the line can go straight or alltime is up, but you cannot set such a mode when the speed will drop with increasing temperature. When finished, click “Apply” and close the settings window.
Autostart at PC startup
</p>In order for the afterburner to start automatically with the operating system, and immediately display the specified parameters, you must:
- Upon completion of the settings, activate StartUp in the lower left corner of the interface.
- Open the settings menu and put a tick in front of the option “Run with Windows”.
At the bottom right are the profile slots. Press the buttonSave', After which all five slots will flash, andselect the cell with the desired number. Logically, right away, they select 1, then 2, and so on. Thus, you can save 5 different configurations, which is very convenient if you often switch mining algorithms.
Advanced MSI Settings
Power Trains Mining Set
The advanced settings menu contains 5 tabs.
- The main ones.
- Cooler.
- Monitoring
- Profiles
- Interface.
We have already introduced you to the first two points. The monitoring tab is used to configure the period of polling sensors and column graphs. In the profiles window, you can set hotkeys for activating saved parameters. The last tab will help you change the look of the program.

Conclusion
There are others, no less effective andconvenient graphics card overclocking applications for mining, but the afterburner came out first, so many just got used to it. This application has a beautiful and convenient graphical shell and developers regularly release new versions. The msi afterburner program is recommended for miners digging in Windows. Good luck to everyone!
