Mining BIOS

1. You can use the latest BIOS on the official website.
the settings have been adjusted in the new BIOS. There are operation steps in DOS. You can refer to the following
mining graphics card to install a driver. Mining generally uses the same chip graphics card

2. Recently, the price of bitcoin has been rising. Last week, the single price of bitcoin broke through the RMB 20000 mark. Compared with speculation, what is more exciting is self-sufficient mining. The assembly of mining machine has become the focus of attention

in order to cater to the current mining boom, major manufacturers have released corresponding mining motherboards to seize the market. What can be inserted into the magic board of 13 graphics cards, super stable power supply and so on. It's easy to ignore the BIOS on the motherboard while configuring the heap. Although the current mining has experienced several years of training, but at present, when we assemble the mining machine, we still need to toss BIOS, in order to use the multi card to improve the performance of mining. For most mine friends, it is a great test to brush BIOS. If the brush is broken, the whole board will be scrapped. The major manufacturers in improving the corresponding configuration at the same time, but rarely invest too much research and development in BIOS. The reason is that the BIOS of mining machinery is difficult to develop, the research and development time is too long, and the cost recovery is slow. Therefore, compared with the BIOS of special mining machine, it is better to improve the profit of motherboard configuration
there are many mining motherboards on the market, but there are few motherboards with BIOS specially set for mining. Recently, Meijie has developed a special intelligent BIOS for the newly upgraded professional mining motherboard sy-b85-btc. The BIOS of this motherboard can intelligently identify 6 graphics cards. Save all mine friends time, plug and play, convenient and fast, mining no longer wait. We all know that AMD's mining graphics cards have been sold crazy recently, and NVIDIA can't sit there any more. It is reported that NVIDIA will launch a professional mine card gtx1060, which has no display output interface. Meijie, with foresight, has set up integrated display output for mining BIOS by default. After that, NVIDIA's gtx1060 can be perfectly adapted, more than enough

Meijie sy-b85-btc is based on the scheme design verified by mining instry for many years, and also continues the characteristics of Meijie's high efficiency and low price mine board. As an ATX board, Meijie is equipped with 7-phase luxury power supply, all solid black gold capacitor and PCI-E stabilized capacitor design, to ensure stable and safe mining< The sy-b85-btc adopts B85 chip design, supports the fourth and fifth generation CPU of lga1150 interface, and supports lga115x and LGA775 radiator. It is convenient for miner to upgrade the motherboard and use the old CPU and radiator at the same time. Of course, six PCI-E slots are essential for the motherboard specially designed for mining. Three of them are pci-ex16 slots and three are pci-ex1 slots, which can support up to 6 cards mining. Meijie sy-b85-btc also supports 7 * 24-hour all-weather mining, lightning protection, over-current protection, over-voltage protection, high temperature protection, etc. Such a sharp artifact, how can you not let mining friends heart?

3. Phoenix is the BIOS chip 1. Phoenix Phoenix Phoenix (American city) 2. Phoenix, the eternal bird, the perfect person, the perfect thing 1. BIOS classification at present, the more popular motherboard BIOS on the market mainly includes three types: awardbios, ambiios, Phoenix BIOS. Awardbios is a BIOS proct developed by awardsoftware company, which is most widely used in the motherboard at present. The awardbios has complete functions and supports many new hardware. At present, most mainboards in the market adopt this kind of BIOS. Amibios is the BIOS system software proced by AMI company. It was developed in the mid-1980s. Most of the early 286 and 386 used amibios. It has good adaptability to all kinds of software and hardware and can ensure the stability of system performance. After the 1990s, green energy-saving computers began to be popular, but AMI failed to launch a new version in time to adapt to the market, which made the award BIOS occupy more than half of the country. Of course, now AMI also has a very good performance, the new version is still powerful. Phoenix BIOS is the proct of Phoenix company. Phoenix means Phoenix or the immortal bird in Egyptian mythology, which has the meaning of perfect thing. Phoenix BIOS is mostly used in high-end 586 original brand computers and laptops. Its picture is simple and easy to operate. 2. The method to determine the BIOS version of the motherboard to upgrade the BIOS, the premise is that the BIOS on the motherboard must be flash BIOS (flash memory), ordinary BIOS can not be upgraded by software method. To identify whether it is flash BIOS or not, you can check the user manual of the computer motherboard (flash BIOS is used in most motherboards). You can also check whether there is a new version of the BIOS of the motherboard on the homepage of the motherboard proction company according to the brand and model of the motherboard. If there is, of course, it can be judged as flash BIOS. If it is the original machine, you should go to the manufacturer's home page to check whether there is BIOS upgrade software for the machine. After confirming that the BIOS on the motherboard can be upgraded, we should also determine its current version number. The specific methods are as follows: restart the machine, and we can see the following boot images (it can't be mapped, just in the lower left foot of the screen or press del key to view). To view these images carefully, press the "pause" key in the upper right corner of the keyboard.

4. It mainly uses the skill of "seeing and touching". When the power is turned off, check whether the components are connected correctly, whether the capacitance and resistance pins are in good contact, whether the surface of each component is scorched or cracked, and whether the copper foil on each circuit board is burnt out. At the same time, you can touch the surface of some chips with your hand to see if there is a very hot phenomenon

replacement method

when it is uncertain which component is responsible for some fault phenomena, the suspected part can be replaced

5. There is such an operation. The so-called BIOS brushing is only applicable to some graphics cards, not all graphics cards. Some graphics cards are upgraded by manufacturers. For example, HD5750 and hd6750 increase the frequency of GPU, and a small amount of them increase the processor. But the core GPU is the same. At this time, you can brush BIOS to change 5750 into pseudo 6750 to improve the performance. This technique is similar to overclocking. But the success rate is not 100%.

6. Must upgrade version by version!!! Because most of the upgrade files are based on the files of the previous version, if you upgrade to the latest one directly across levels, it is likely that the upgrade will fail e to the lack of the files of the previous version.

7. Because the ROM used by BIOS is much slower than the ordinary memory RAM we use, people think of ing the information in the ROM of BIOS to the memory mole (RAM) we plug in after startup to improve the reading speed, and the BIOS information in RAM is called BIOS shadow memory. Boot - press del to enter BIOS to view. Biosshadowed (BIOS mapping is divided into system BIOS mapping, video BIOS mapping and video memory buffer!) Set videobiosshadow to enabled. The BIOS on the graphics card is mapped to the memory to improve the display speed. Set systembiosshadow to enabled. The system BIOS is mapped in memory to improve performance. Set videobioscacheable to enable. Map the BIOS on the graphics card to the cache. Set systembioscacheable to enabled. Map the BIOS of the motherboard to the cache. Generally, you can find it by pressing enter in the main menu advanced IOS features. Of course, some motherboard BIOS projects are not included in this. It can also be found in the integrated peripherals global settings. Use the keyboard pagedown to adjust to enabled for on, otherwise disabled for off. After adjustment, press F10 key to save, exit and restart the computer. This function is rarely used in systembiosshadow and systembioscacheable, so it is unnecessary to adjust the open mapping. If you want to have a try, you can also turn off the mapping function if it causes system function abnormality or conflict. Videobiosshadow and videobioscacheable have been set and enabled on machines with poor configuration. After using them, we feel that they have obvious improvement and suggest that they can be enabled.

8. Mining mainly depends on the graphics card, because mining is the graphics card in the calculation, not the CPU in the calculation. Of course, it has something to do with the motherboard. There are several major requirements:
1. Six PCI-E slots are provided to connect six graphics cards

2. BIOS optimization, which can be identified by inserting 6 cards, does not need manual adjustment
3. Stable operation and unstable motherboard may cause automatic restart and shutdown, affect efficiency, or cause short circuit graphics card burn out
at present, B250 / B350 mining motherboards are mainly promoted in the market. Some new ones are very interesting, such as 7 cards / 8 cards. However, these schemes have not yet passed the test. There may be unstable factors, and some of them are not in stock. In fact, the previous 8 series are more suitable for mining. The ms-b85-btc made by the furniture factory is a very good mining board. After years of mining scheme verification, 6 PCI-E, BIOS automatic identification, and PCI-E voltage stabilizing capacitor design are added. The mining is stable, and the shutdown cost is low.

9. Save it
this proct can't support mining at all.

10. I don't know how to revise it, but what I want to say is that people say 7970 × 4 is the starting configuration. You are such a weak 6750. Don't you think you can't dig one in a month? Mining is a combination of configuration, not an AMD graphics card on the line
