H81 mining collapse
"Graphics card mining" is actually to use the graphics card to dig bitcoin, so that the graphics card can work with high load, and the eliminated ones will become mine cards. Generally, the core PC board on the back of mine cards is seriously discolored< br />
for mining machines, the most important thing is the graphics card. Generally, you can choose the most basic motherboard that supports 6 graphics cards, and later you can choose the more complex motherboard that supports more than 12 graphics cards. The specific suggestions are as follows:
1. CPU - CPU can choose the most basic and cheap CPU, as long as you can bring the system up normally, Generally, you can choose Intel's g3900 CPU with a unit price of about 200 yuan< Operating system is too laggy. If you use 6 graphics cards, you need at least 4G of memory. If you are 12 graphics cards, the windows operating system needs at least 8g of the memory. Otherwise, the system will be very stuck and then can not work normally. The Linux operation system can be 4G memory. < br > />2.
3. Motherboard - it is recommended for novices to directly choose the special mining motherboard of Yingtai series. The models are tb250 BTC with 6 card slots and tb250 btcpro with 12 card slots, as well as H81 series motherboard of Huaqing
4. Hard disk - SSD hard disk is needed for hard disk, because the reading speed is fast, and virtual memory needs to be set. SSD hard disk can improve some performance theoretically. If you use Windows system, you need at least 64GB, and Linux system can use 16GB
5. Operating system for windows, it is recommended that win10 system, corresponding to NVIDIA series and AMD Series graphics cards, can recognize up to 8 cards respectively. If the motherboard of 12 cards needs N cards and a cards to be mixed, then we can make full use of the motherboard graphics card slot
6. Graphics card - the mainstream mining graphics card models are amd Series graphics cards rx470, rx570, rx580, NVIDIA Series graphics cards gtx1060, gtx1070 and so on. It is recommended to choose 4G or more memory, and 8g is the best.
1. This does not need too many settings, the best graphics card to use NV graphics card 2, the system win10, the power supply is sufficient, the latest version of the motherboard BIOS, the BIOS settings for the main graphics card to PCI e
2, the hard disk must be GPT format, the system must be 64 bit, UEFI does not support 32-bit system
note: UEFI can boot x64 system on MBR disk, but it needs special settings
3. The traditional MBR partition only supports 2.2t hard disk, and the hard disk larger than 2.2t needs GPT, and the BIOS supports opening the integrated graphics card (which can be set) to double display
However, Qicaihong does not have the motherboard of h81-a. h81-a is an ASUS brand and can not support six graphics cardsselect factory settings in BIOS, press enter to save and exit, then discharge the main board COMS, and then enter BIOS to set
{rrrrrrr}
extended data:
seven rainbow motherboard boot into BIOS method:
1, you can press del key to enter BIOS
2. You can boot the BIOS directly without connecting the hard disk
there are two conditions for supported graphics cards:
1. Several graphics cards are supported in a few slots, and the expansion slots of ciex1 and pciex16
The main board power supply and power supply are enough. When most motherboards are turned on, you can enter the BIOS interface by continuously pressing the "del" key. Some notebooks can only enter the BIOS interface by pressing F2 BIOS is not only the basic input and output system of computer motherboard, but also the basic system of communication and recognition between computer hardwarecontents include: power settings, hardware on / off, hardware working mode settings, overclocking, etc. The contents of bios are in English. Now some brands of new motherboards support Chinese. The options in BIOS can't be set randomly without understanding its specific function, so as to avoid the computer can't boot normally
its main function is to provide the most direct hardware setting and control for the computer. In addition, BIOS also provides some system parameters to the operating system
the change of system hardware is hidden by BIOS, and the program uses BIOS function instead of directly controlling the hardware. Modern operating systems ignore the abstraction layer provided by BIOS and directly control hardware components
BIOS Setup program mainly manages and sets the basic input and output system of the computer to make the system run in the best state. Using BIOS Setup program can eliminate system faults or diagnose system problems
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
Qicaihong has proced a h81a-btc V20 motherboard, which can support the mining of 6 graphics cards; Now that the mine is in trouble, it should not be the time to enter.
therefore, it is recommended to select the motherboard of B85 chipset.
such as 53 × 89 =
that's 53 × 90-53 = 4770-53 = 4717, be simple
or 67 × 91=67 × 90 + 67 = 6097
this still depends on a little computing power
there is another mouth algorithm:
for example, 38 × 94
can be regarded as 3 × nine × 100+3 × 4+8 × 9 × 10+4 × 8 = 2700 + 840 + 32 = 3572
How about it? It's all single digit multiplied by single digit. Is the final sum a little easier than direct calculation?
