1. Miner components include CPU, GPU, motherboard and hard disk, similar to a high configuration computer with a hard disk. Self assembly mainly depends on which aspect of hardware performance you want to highlight
mining machine has computing power, display card mining machine and storage mining machine. Daotong storage has long been concerned about the dynamic and hardware supply of mining machine, and its own components will be cheaper than those of the manufacturer< br />
2. According to the requirements of the manual, first measure whether the red and green lines correspond to the L1 of the interface; Is the yellow and black line corresponding to L2? If so, it must be the correct connection. Although the telephone line can be divided into positive and negative poles, the terminals can be connected at will, so there is a rectifier directional circuit inside the telephone. Even if the L1 and L2 lines are wrongly connected, the equipment will not be burnt out, so you can safely and boldly test.
3. It's a long story about the difference between 32-bit and 64 bit systems. First of all, let's understand the architecture technology of CPU. Usually we can see that there are x86 and x64 marks on computer hardware. In fact, these are two different CPU hardware architectures. X86 stands for 32-bit operating system and x64 stands for 64 bit operating system. So what does the "bit" in 32-bit and 64 bit mean? Compared with 32-bit technology, this bit of 64 bit technology means that the data width of cpugprs (general purpose registers) is 64 bits. The 64 bit instruction set is the instruction that runs 64 bit data, that is, the processor can run 64 bit data at a time. Let's take a simple but not particularly accurate example: the 32-bit throughput is 1m, while the 64 bit throughput is 2m< First, download a ghost version of win7 operating system, and now Doudou takes "deep technology ghost win7 SP1 x64 computer city installed version v2013.10" as a demonstration.
4. Ethereum? What is it, Ethernet?
5. How to use the Linux system mining, to use the service of the HA Yu miner, only need two steps, you can mine on the Linux system
-
open the website, input the mobile phone number, select how many CPUs you want to use for mining, the default is to use 50% of the CPU for mining, click to generate your exclusive command and
in two steps, you can mine on Linux system, the money you dig only needs to go to the website of hayu miner, enter your mobile phone number to withdraw< br />
6. Build / env.sh go run build / ci.go install. / CMD / geth
make: * * [geth] error 1
there is no such directory, or the directory has insufficient permissions
7. My computer - & gt; Attribute - & gt; Advanced - & gt; Environment variables - & gt; Add the following environment variables to the system variables:
java_ The home value is: the directory where JDK is installed, and mine is C: &# 92; Program Files\ Java\ jdk1.6.0_ 34
the classpath value is:;% JAVA_ HOME%\ lib\ tools.jar;% JAVA_ HOME%\ lib\ dt.jar;% JAVA_ HOME%\ bin;( Pay attention to the & quot& quot; To add)
Path: append at the beginning.;% JAVA_ HOME%\ bin;% JAVA_ HOME%\ jre\ bin;( Pay attention to the & quot& quot; To add)
after the installation, you can check whether the JDK is installed successfully. Open the CMD window and enter Java – version to view the version information of JDK.
8. Of course, it's a miner. You can only buy leeks. Ethereum mining machine is now famous. I recommend Feixun's Ethereum mining machine C8. First of all, C8 reces the mining threshold, eliminates the mining machine's cost, and allows everyone to enter the
blockchain. It also saves effort, and does not need to install their own machines. I have bought several, Now I'm in the process of installation and storage. I'll wait for the official excavation. Then I just need to look at the Ethereum wallet every day.
