How to brush BIOS for low computing power of graphics card minin

1. 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?

2. 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%.

3. 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.

4. 1. Mine card generally needs the specified driver version
2. The 382.33 384.76 384.96 driver installed on the official website can't work, only the 382.53 driver can work normally
3. If the driver of this version can not be used normally, you need to contact the official technician to provide the driver file for re installation.

virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum" is popular in the circle

network virtual currency can be roughly divided into

[1] the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency

[2] the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services

[3] the third kind of virtual currency on the Internet, such as bitcoin (BTC), lightmoney (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency

[4] the application of computer communication technology and the development of Internet as a new media are the technical basis of network marketing. Internet was born in the 1960s. With the development of network protocols and related hardware and software procts, Internet has graally changed from military to commercial and civil. From the 1990s, the Internet has graally entered into the daily life of society. As a matter of fact, the Internet, as an emerging media, has developed faster than all other technologies in the past. It took 38 years for radio to reach 50 million audiences, 13 years for television, and only 3-4 years for Internet. Therefore, the Internet is considered to be the technological change that has the greatest impact on the world economy in the past 100 years

6. Required software:
1. Imager's grinding disc (I believe it's not strange, especially for players of imager's graphics card, they can also perfectly support other brands of graphics card)
2. Nibitor (editing software for BIOS of graphics card)
3. Gpu-z
4. Some ing software, 3DMark06, and the next point of game, such as island crisis, biochemical crisis, are used to test ing after overclocking
Start:
1. First, use the imager disc to soft overclocking the graphics card, and the amplitude should not be too large; After the application, repeatedly run 3dmark 06 or play an island crisis for 1 or 2 hours, ring which there is no splash screen or crash phenomenon, indicating that your overclocking is successful and stable. Write down the frequency of overclocking data, core, video memory and shader
2. Open gpu-z, backup and save the BIOS of the graphics card
3. Open nibitor software to edit the frequency of the original BIOS, as long as the data of soft overclocking is rewritten and saved separately. The order is core - shader - video memory
4. Then click magic BIOS and select the BIOS you edited with nibitor to swipe in. After a few seconds, it will be displayed that you have finished restarting the computer
5. Enter the system again and use GPU to check whether the default frequency of the graphics card is the modified data

7. Methods and steps of swiping BIOS of graphics card under Windows:
required software:
1. Imager's grinding disc (I believe it's not strange, especially for gamers of imager's graphics card, they can also perfectly support other brands of graphics card)
2. Nibitor (editing software for BIOS of graphics card, the current version is v5.4)
3. Gpu-z
4. Some ing software, 3DMark06, and some abnormal games, such as island crisis Biochemical crisis, for overclocking after the test machine
Start:
1. First, use the imager disc to soft overclocking the graphics card, and the amplitude should not be too large; After the application, repeatedly run 3dmark 06 or play an island crisis for 1 or 2 hours, ring which there is no splash screen or crash phenomenon, indicating that your overclocking is successful and stable! Write down the frequency of overclocking data, core, video memory and shader
2. Open gpu-z, backup and save the BIOS of the graphics card
3. Open nibitor software to edit the frequency of the original BIOS, as long as the data of soft overclocking is rewritten and saved separately. In order is the core - shader - video memory
4. Then click magic BIOS and select the BIOS you edited with nibitor to swipe in. After a few seconds, it will show that you are finished and restart the computer Don't turn off the power, otherwise you will be finished if you interrupt the power by brushing BIOS (HA HA)
5. Enter the system again and use GPU to check whether the default frequency of the graphics card is the modified data!

8. Soft change is OK, no need to brush BIOS, easy to brush bad

your graphics card is best ATI graphics card

Introction to soft change method, go to Google Search & quot; AIT soft Reform & quot; That is

http://www.oc.com.tw/article/0803/readarticle.asp?id=6344

of course, the public version of graphics card, sapphire, Dylan Hengjin, ASUS and other first-line brand public version procts are selected for transformation< br /> http://diybbs.zol.com.cn/frmView.php?frameon=yes&subcatid=161&bookid=23853&ref0=http :// www..com/s?tn=360se_ 3_ DG & ie = GB2312 & Bs = ATI + radon + HD + 3850 & SR = & z = & CL = 3 & F = 8 & WD = ATI + radon + HD + 3850 + +% C8% ed% B8% C4 & CT = 0

only the low-end graphics card of MX400 has been soft modified, but the latest graphics card of 3850 has not been tried. However, after all, it's a soft change. It can only improve the professional drawing ability of the graphics card, and there is still a certain gap with the professional graphics card. However, for general applications, it's enough. I'm afraid there is no perfect crack driver, so I can only test which one is better.

9. 1. Preparation:
generally, there is a flash ROM jumper switch on the motherboard, which is used to set the read-only / read-write status of BIOS. After shutdown, find it on the motherboard and make it writable (enable or write). The new motherboard can be set in CMOS, please refer to the motherboard manual for details. In addition, the author suggests setting it to boot from disk a in CMOS.
