570 mining overclocking
Overclocking itself has a loss on the graphics card, so you don't need to overclock when you play enough games. When you feel that the performance of large-scale games is poor, you can overclock the core frequency of the graphics card to improve the performance, but don't overdo it too much. In the case of the original frequency, it's better to exceed 5% to 8%, such as the core frequency of 1000, 1100 and 1150
it's only a lie to say that the heat dissipation is good, the power supply is stable, and it can last for about one year (working with full load for a long time every day)
Yes , on August 21, Beijing time, recently, TSMC officially announced that the 7Nm chips, which were put into large-scale proction in 2018, have now proced more than 1 billion 7Nm chips. At the same time, more than 100 procts began to use the 7Nm chips proced by TSMC
it is understood that TSMC's first 7Nm chip started large-scale proction in April 2018. Meanwhile, the billionth 7Nm chip was proced in July this year. In these 27 months, TSMC has to proce more than 37 million 7Nm chips every month
according to the data, the first batch of TSMC 7Nm procts include bitmainland's miner chips, Xilinx's FPGA chips, apple A12, Huawei's Kirin 980, etc

Introction to Taiwan integrated circuit manufacturing Co., Ltd.
Taiwan integrated circuit manufacturing Co., Ltd., Chinese abbreviation: TSMC, English abbreviation: TSMC, belongs to semiconctor manufacturing company. Founded in 1987, it is the world's first professional integrated circuit manufacturing service (wafer foundry) enterprise. Its headquarters and main factories are located in the Science Park of Hsinchu City, Taiwan Province, China
in 2017, the market share was 56%. In the first quarter of 2018, the combined revenue was US $8.5 billion, a year-on-year increase of 6%, the net profit was US $3 billion, a year-on-year increase of 2.5%, the gross profit rate was 50.3%, and the net profit rate was 36.2%, of which the 10 nanometer wafer shipment accounted for 19% of the total wafer revenue. As of April 19, 2018, TSM has a market value of US $217.4 billion and a static P / E ratio of 19
on July 16, 2020, at the TSMC's second quarter performance presentation meeting, the spokesperson disclosed at the meeting that he did not plan to continue to supply goods for Huawei Technology Co., Ltd. after September 14. The new regulations on Huawei announced by the US government on May 15 will take effect on September 15. On July 13, 2020, Taiwan media juheng.com reported that TSMC had submitted an opinion to the US government, hoping to continue to supply Huawei after the 120 day grace period of Huawei's ban expired

I. common attack means of hackers
hacker attack means can be divided into non-destructive attack and destructive attack. Generally, non-destructive attack is to disturb the operation of the system, and does not steal system data. It usually uses denial of service attack or information bomb; The purpose of destructive attack is to invade other people's computer system, steal confidential information of the system and destroy the data of the target system. Here are four common attack methods of hackers (Note: password cracking is also one of the common attack methods of hackers)
1. Backdoor program
when programmers design some programs with complex functions, they usually adopt the idea of molar programming, dividing the whole project into multiple functional moles for design and debugging respectively. At this time, the backdoor is the secret entrance of a mole. In the program development phase, backdoor is easy to test, change and enhance the mole function. Under normal circumstances, the backdoor of each mole needs to be removed after the completion of the design, but sometimes e to negligence or other reasons (such as leaving it in the program for future access, testing or maintenance), the backdoor is not removed. Some people with ulterior motives will use the exhaustive search method to find and use these backdoors, and then enter the system and launch attacks
2. Information bomb
information bomb is an attack method that uses some special tools and software to send a large amount of information exceeding the system load to the target server in a short time, causing the target server overload, network congestion and system crash. For example, sending a specific combination of UDP packets to an unpatched Windows 95 system will cause the target system to crash or restart; Sending specific packets to a certain type of router causes the router to crash; Send a lot of spam to someone's e-mail to "burst" this mailbox, etc. At present, the common information bombs are mail bomb, logic bomb and so on
3. Denial of service (DOS) is also called distributed d.o.s attack. It uses a large number of packets that exceed the processing capacity of the attacked target to consume the available system and bandwidth resources of the system, and finally results in the paralysis of network services. As an attacker, first of all, he needs to intrude and control a website through conventional hacker means, and then install and start a special instruction on the server that can be issued by the attacker to control the process. When the attacker gives the IP address of the attack object to the process as an instruction, these processes start to attack the target host. This method can concentrate a large amount of network server bandwidth to attack a specific target, so it has great power. In an instant, the bandwidth resources of the attacked target can be exhausted, resulting in server paralysis. For example, in 1999, the University of Minnesota was attacked by hackers in this way
4. Network monitoring
network monitoring is a management tool to monitor the network status, data flow and information transmitted on the network. It can set the network interface in monitoring mode and intercept the information transmitted on the network. That is to say, when the hacker logs in to the network host and obtains the super user permission, if he wants to log in to other hosts, he can log in to other hosts, Network monitoring can effectively intercept the data on the Internet, which is the most commonly used method by hackers. However, network monitoring can only be applied to the host physically connected to the same network segment, which is usually used to obtain the user password.
