Mining BIOS set to integrated display
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?
The size of the integrated display memory can be adjusted in the BIOS. The specific operation method is as follows:
1. Press del to enter the BIOS when starting up. The adjustment position of the integrated display memory is in the chipset - North Bridge sub item
extended materials:
integrated graphics card is a special kind of graphics card
the integrated graphics card generally does not have video memory, but uses part of the main memory of the system as video memory, and the specific amount is generally adjusted automatically and dynamically according to the needs of the system. Obviously, if the use of integrated graphics card to run requires a lot of memory space, the impact on the whole system will be more obvious. In addition, the frequency of system memory is usually much lower than that of independent graphics card, so the performance of integrated graphics card is inferior to that of independent graphics card. It is not necessary to use the integrated graphics card when using the motherboard of the chipset with integrated graphics card. The motherboard can completely shield the integrated graphics card, but it is rarely done because of the cost
in addition, some integrated graphics card chipsets can also support separate graphics card slots, such as Intel's G-Series chipset, while some no longer support special graphics card slots, such as Intel's GL Series chipset. The main board integrated by the north bridge chip of the main board is called the integrated main board. The display card chip integrated by the north bridge chip is the core of the integrated graphics card, which together with the video memory constitutes the integrated graphics card

1. Click ADF test on the panel
2. Enter the command dfuller in the open dialog box to start stationarity test
Stata
is a complete and integrated statistical software that provides data analysis, data management and drawing professional charts for users. It provides many functions, including linear mixed model, balanced repetitive model and polynomial proby model< The statistical function of Stata is very strong. In addition to the traditional statistical analysis methods, it also collects new methods developed in recent
20 years, such as
Cox
proportional risk regression, index and
Weibull
regression, logistic
regression of multiple results and ordered results,
Poisson
regression, negative binomial regression and generalized negative binomial regression, Random effect model, etc.
The table on the left side above is used to calculate the following data, and there is no need to mention it in the process of analysis
from top to bottom on the right side
1. Number of OBS is the sample size
< P > 2. F is the F test value of the model, which is used to calculate the following P & gt; F3.P> F is the probability that the model F test falls in the small probability event interval. Your model confidence level is 0.05, which means P & gt; If the value of F is greater than 0.05, then the model has a high enough probability to fall in the small probability interval of F function. In short, if the value is greater than 0.05, there is a problem in the model setting, and you need to reset the model
4. R-square is the R & amp; amp; amp; D of the model# 178; Value, goodness of fit, the larger the number, the higher the goodness of fit between your model and the actual value, the better the model is
5# 178;， Follow R & amp# 178; Almost, just pay attention to one
6. Root MSE is the standard deviation of resial error. The larger the value is, the greater the fluctuation of resial error is, and the more unstable the model is (I don't pay much attention to this value when I analyze it)
lower table
-
coef. It is the estimated coefficient value
-
std.err is the standard deviation, which is of great significance, Generally, the standard deviation is required to be expressed in papers. The larger the number is, the more imprecise the model is, and the smaller the model is, the better
-
t is the t-test value. T-test is used to test whether a certain coefficient is significantly different from 0. In analysis, this value is generally meaningless and mainly used to calculate P & gt; t
P> t. This value is the main parameter to observe whether an explanatory variable is effective, or for the confidence level of 0.05 you set. If this value is greater than 0.05, it means that the corresponding explanatory variable can not pass the t test and is unqualified in the model, so it needs to be adjusted
-
and the latter two are the confidence interval, the 95% confidence interval, Generally, it has little significance in the paper
< / OL >
and then the analysis selects your useful parameters to do, I study economics, generally the most useful parameter is P & gt; F,coef，P> t. Se and so on, as well as BIC, Vif these, in simple regression, these will not be calculated, need other commands
the highlight moment of dogcoin is undoubtedly Musk's speech to bring dogcoin into space, which makes dogcoin soar instantly musk has always been a supporter of virtual currency, so many of his remarks will also drive the economy of virtual currency, and musk is also one of the investors of virtual currency
as a new kind of virtual currency, dog coin has a very fierce momentum. The main reason is that dog coin has been supported by many business tycoons and caught up with the popularity of virtual currency
The value-added of
bitcoin is the novelty and popularity of virtual currency, which has set off a large-scale virtual currency frenzy
However, e to its particularity, virtual currency itself will fluctuate violently, so we need to be cautious and carefulEOP = etch on process.
