UEFI of ASUS motherboards will provide mining support. UEFI of ASUS motherboards will provide support for mining How to enable 4g in BIOS
It would not be an exaggeration to say that the leading manufacturers of personal platforms “ overslept» cryptocurrency boom in terms of its support from its motherboards. When Bitcoin mining had just started, and economical ASIC gadgets had not yet entered the game (with billions of dollars in turnover, the extraction of digital monetary assets is still perceived as a game in which sooner or later the bank would be “broken”), installing four video adapters was the norm.
Today, the bill for computers, the core of which are graphic processors installed on one mining platform, has exceeded a dozen, and already a dozen PEG adapters are perceived as a “problem”: the cost of the motherboard, central processor, plus memory and storage is significantly visible against the background of the total cost video cards, even taking into account their exorbitant prices.
The first bell rang in the spring of this year, when the problems of installing professional video cards with colossal amounts of video memory on board made themselves felt. It became obvious that placing the range of graphics accelerator addresses that has grown out of the “short pants” of 32-bit addressing in a 4-gigabyte space is both difficult and problematic (why, it is explained). To solve this problem, ASUS then equipped its products based on the flagship (at that time) Intel Z270 chipset with the option Above 4G Decoding:

The ability to 64-bit address video adapter resources outside the 32-bit space (which is four gigabytes of addressable memory) came in handy for Ethereum miners. Vitalik Buternin’s new cryptocurrency has revived the mining process on personal platforms, first of all, demonstrating a confident increase in exchange rate value.

It turned out that if graphics adapter drivers support 64-bit addressing, then, thanks to enabling the option Above 4G Decoding in UEFI BIOS settings, you can provide mining on almost any number of video cards. Their use will be regulated by completely different factors that do not depend on the initialization of the personal platform.
Sensitively responding to the needs of a skinny market by today's standards, ASUS quickly updated the UEFI of motherboards that were not originally intended for cryptocurrency mining. Fortunately, the hardware was completely ready for this. The process stretched from the beginning of March to the end of July, when Above 4G Decoding has become the default option for all new products.
The update to the expandable proprietary software interface even affected such market veterans as ASUS H170 Pro and ASUS Z170-A. Developed more than two years ago, these platforms based on various versions of the 170 chipset from Intel, however, are still within the warranty window (remember that the Taiwanese manufacturer guarantees three years of service for its motherboards). Their use in mining farms is fully justified - entry-level budget processors cover cryptocurrency needs, significantly reducing the overhead costs of an infrastructure startup.
Those who like to study the capabilities of the BIOS (UEFI) of their computer or laptop can often find in it an option called “Above 4g decoding”, which has two states - Enabled (activated) and Disabled (disabled). It is most often located on the “Advanced” or “Boot” tab and is almost always initially turned off.
In this article we will tell you what this parameter is responsible for and when it needs to be activated.
What does Above 4g decoding do?
To answer this question, we will provide a short reference on the functioning of a computer. It is no secret to many that the interaction of some devices connected to the motherboard with the central processor is carried out through RAM. Data, for example from a video card, awaits its turn in a specially designated area of RAM before being processed by the central processor.
This leads to the fact that the performance of the RAM is reduced in its remaining tasks, which can result in a decrease in overall system performance.
To solve this problem, a technology was invented to move a section of RAM for data exchange between the processor and PCI devices beyond the 4 GB volume. Of course, if you have more than 4 GB of RAM. It's called Above 4g decoding.
But for this option to work, several conditions must be met:
- The amount of installed RAM must be more than 4GB;
- The operating system must be x64;
- Devices connected to PCI and PCI-Express slots must support 64-bit addressing.
Do I need to enable Above 4g decoding?
This should only be done if you are completely sure that all the above conditions are met on your computer. Otherwise, activating this setting may result in .
If this has already happened to you, then you can correct the situation by resetting the BIOS settings, for example from the motherboard for a few minutes.
Nowadays, the words “Mining”, “Blockchain”, “Bitcoins” are heard literally everywhere: from tram passengers to serious businessmen and State Duma deputies. It is difficult to understand all the intricacies and pitfalls of these and related concepts, however in the database on our website You will quickly find comprehensive information covering all aspects.
Briefly, all the necessary knowledge will be presented in this article.
So, let's start with the blockchain. Its essence is that computers are united into a single network through a set of blocks containing automatically encrypted information that gets there. Together these blocks form a database. Let's say you want to sell a house. Having completed the documents, you need to go to a notary, then in his presence, having certified the transfer with his signature, they will give you the money. It takes a long time, and besides, you have to pay a fee.
Thanks to blockchain technology, it is enough to:
- Reach an agreement.
- Find out the recipient's account.
- Transfer money to the recipient's account.
And not just money. You can issue an electronic signature and send documents and any other information, including confidential information. Again, notaries and other officials are not needed: it is enough for you and the recipient (be it a private person or a government agency) to identify yourself in your computer.
The transaction takes place over a secure communication channel, no one sees (including banks and the state) who transferred what and to whom.
The possibility of hacking is excluded due to the huge number of blocks described above. A hacker needs to find a cipher for each block, which is physically impossible.
Other uses of blockchain:
- Insurance;
- Logistics;
- Payment of fines
- Marriage registration and much more.
The concept of cryptocurrency is closely related to blockchain. Cryptocurrency is a new generation of decentralized digital currency created and operating only on the Internet. No one controls it; currency is issued through the work of millions of computers around the world, using a program to calculate mathematical algorithms.
Briefly it looks like this:
1. You intend to transfer money to someone.
2. A mathematical code is generated, passing through the blocks already known to you.
3. Many computers (often a collection of them, with powerful processors and, as a result, greater bandwidth) process digital information, transmitting them to the next blocks, receiving a reward for this (some transactions can be made for free)
4. The mathematical code reaches the recipient’s electronic wallet, and money appears on his balance.
Again, as is the case with blockchain, cryptocurrency transfers are not controlled by anyone.
Although the database is open, with all the addresses of those transferring and receiving money, no one knows the owner of this or that address from which the transfer is made, unless the owner himself wants to tell.
There are many currencies that work on a similar principle. The most famous is, of course, Bitcoin. Also popular are Ethereum, Rittle, Litecoins, Numits, Namecoins and many others. The difference between them is in different types of encryption, processing and some other parameters.
Miners make money from money transfer technology.
These are the people who created the above-mentioned set of computer video cards, which generates new blocks that transmit digital information - bitcoins (or rittles, or any other cryptocurrency). For this they receive a reward in the form of the same cryptocurrency.
There is competition between miners, because... The technology is programmed to become more complex with each transaction. At first it was possible to mine from one computer (2008), but now such a currency as Bitcoin is simply unprofitable for individuals: you need a lot of video cards (they are collectively called farms), with enormous computing power. To do this, separate rooms are rented; the energy costs for work are comparable to the costs of industrial enterprises.
But you can make money on other, less popular, but developing cryptocurrencies. There is also a distinction between solo mining and pool mining. Solo is the creation of your own farm, the profit is taken for yourself. The pool brings together other people with the same goals. You can earn much more, but you have to share it with everyone.
Both individuals and entire states have become interested in the prospects for using blockchain technology in general and cryptocurrencies in particular.
Cryptocurrency is legal in Japan. In Russia, next year they are going to adopt regulations on the legalization of blockchain, cryptocurrency transfers and mining. It is planned to transfer some operations to the blockchain framework. It makes sense to study this in more detail, and, if desired, start earning money. It is obvious that now information technologies will develop and enter our lives more and more.
4G is a fourth generation mobile communication that allows data transfer at speeds exceeding 100 Mbit/s for mobile devices. It is not surprising that more and more users want to know how to enable 4G LTE on Android: previously, such speeds were only available on computers.
Before you try to connect to 4G, you need to make sure that your mobile device supports this standard. If you have a modern smartphone, then no problems should arise, but it is advisable to check its specifications on the manufacturer’s website or in any large online hardware store.
The next stage is checking the operator and coverage area. On the website of each mobile operator there is a network coverage map with the ability to switch between different standards. This map clearly shows that while 2G and 3G are available almost everywhere, the 4G network is just beginning to spread throughout the country. 
Not only the phone, but also the SIM card must support 4G. You can usually find out whether a SIM card will work in the fourth generation network using the USSD command. For example, TELE2 subscribers need to dial *156# on their phone and press the call button. An SMS with the result will be sent in response. If the SIM card does not support the LTE standard, you can replace it with another one at the communication store. After installing a new SIM card into your phone, you will receive a message with settings for working in the fourth generation network.
If the device has “pure” Android without shells from third-party developers, then to enable 4G you must follow these steps:
Changes are saved automatically, so you can exit settings and enjoy all the benefits of modern communications. To connect to the mobile Internet, lower the top menu on the work screen and activate data transfer. 
Another option is in the same section where you selected the network type, check the box next to “Data transfer”. When prompted that an open connection may result in data transfer and associated charges, click OK. The costs in the situation under consideration are mobile traffic included in the tariff by the operator.
On Samsung phones, the process of turning on 4G is slightly different due to the nature of the shell stretched over Android. To use the fourth generation network:
As a result, a Samsung smartphone will start working on a 4G network, provided that other requirements are met: the device supports the standard and is in the coverage area.
If the phone does not work on the 4G network, then the reasons for the problem may be different:
- The mobile device does not support the 4G-LTE standard.
- The operator does not provide services for accessing the 4G network.
- The phone is out of coverage area.
- Mobile Internet is not configured.
If the first three reasons are difficult to deal with, then every user can check the status of the mobile Internet and, if necessary, configure it. The first thing you need to do is make sure that mobile data is turned on.
