1. Do you still want to mine now? The calculation mainly comes from the graphics card. The others don't need to be good. The a-card of the graphics card needs to give the n-card good. There are 629 pieces of i34170, 39 pieces of ice radiator, ASUS b85m-g, 419 pieces, Weigang 8g1600, Weilong, 210 pieces, Seagate 1TB hard disk, 288 pieces, sapphire r9390.4g, 2299 pieces, Hangjia WD500 rated 500W, 299 pieces, and the chassis is free

Hello, according to my experience, 1. First set up the rack, then fix the graphics card, and then plug the CPU and fan, memory, SSD hard disk into the slot of the motherboard, and connect the power supply and motherboard power supply
I hope my suggestions can help you, thank you

mining machine risk
1. The problem of electricity charge
in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
2. Hardware expenditure
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining
3, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
4. R9 390, as far as the performance of the graphics card is concerned, can run smoothly with 1080p resolution full high special effects, but the number of frames is not high.
5. 8GB video memory can meet the current large number of single game, large online games. Don't worry about the lack of 8GB
however, the performance of r9390 is only equivalent to that of gtx1060 3G, so the chip may not be able to cope with large scenes, instead of video memory.

6. Mhol inherits the classic picture style of the series and the feeling of striking easily. The bitter battle with monsters often has an important impact on both sides. The weak hunter will fall down as long as he is hit hard, and the powerful monsters will be graally destroyed because of the hunter's fighting. The strong horns, sharp claws and sharp teeth will be destroyed Powerful tail and wings in the sky. However, this time, the weapons in the hands of the hunter can leave more scars on the terrible enemy, and let the hunter confirm his attack effect more clearly and intuitively
7. This needs to brush the BIOS of the graphics card, R9 390 brushes the BIOS of 390x, so the parameter will be changed. There is a certain risk of brushing the BIOS, which may damage the BIOS,
8. Sapphire R9 390.4g super platinum OC, offer 2299 yuan, give 8g R9 390 cheap 200 yuan, if the money is enough, add 200 directly on R9 390.8g
9. There are seven stations from the exhibition center station to Luohu station by taking the Luobao line: via Gangxia → Huaqiang road → Science Museum → Grand Theater → old street → international trade. It takes about 40 minutes to get to Luohu station, and the ticket price is 3 yuan.
10. Personally, I think it is the domestic security manufacturers who have encountered difficulties from international security evaluation organizations. If it is just because of the default engine problem, it is far fetched indeed. Besides, 360 domestic software is completely formulated according to China's national conditions, which is not difficult for Chinese people to understand<
the following information comes from part of the media:
China's security manufacturers have encountered "sniping" from international security evaluation agencies
on April 30, AV comparatives (hereinafter referred to as "av-c"), AV test and virus bullet (hereinafter referred to as "VB100") issued a joint statement, 360, a well-known domestic security manufacturer, is accused of showing significant differences between the software that participates in the evaluation and the software that is released to users. In the version that 360 antivirus delivers and evaluates, BitDefender engine (hereinafter referred to as "BD engine") is turned on by default, but the version it provides to users turns off BD engine by default and turns on its own QVM engine, As a result, all the certifications and awards that 360 antivirus has won in three evaluation institutions since this year have been revoked
on May 5, Tencent computer housekeeper, another domestic security manufacturer, was also issued a statement by AV test, one of the three major international anti-virus software evaluation organizations, accusing it of participating in the evaluation of related procts of improving user performance optimization mechanism, so as to improve the score in AV test performance evaluation, and then cancel the certification and awards of Tencent related procts in AV test in 2015
the certification and awards have been revoked by international security evaluation organizations one after another. It seems that China's security manufacturers have really encountered problems, which has really strained the nerves of many people who pay attention to the progress of the event. However, if we carefully restore the complete process of this incident, we can find that there are many details worth pondering<
360: the test method is backward and quits the evaluation
after the event, 360 made a response immediately on May 1: 360 has been open, transparent and has nothing to hide about the default BD engine of 360 antivirus in the evaluation version; The reason why BD engine is not turned on by default for ordinary users is that there are a large number of low configuration computers in China
the relevant person in charge of 360 told the legal Weekend reporter that at present, 360 antivirus mainly provides four virus killing engines, including QVM cloud killing engine, QVM local engine, BD engine and Avira engine imported from abroad. In China, 360's self-developed QVM cloud killing engine and local engine are turned on by default, while the two foreign engines are turned on by users themselves
"the domestic computer configuration and network speed are generally low. 360 antivirus provides a light installation package, and the cloud search and kill and QVM engine are turned on by default." 360 relevant person in charge said, "if the user's computer is well configured, you can also turn on BD engine and Avira engine with one click, and use these two traditional engines for free."
in this response, 360 also pointed out that in terms of test standards, av-c and other foreign institutions' virus detection standards are significantly different from China's: for example, hackers and plug-ins are all defined as malicious programs in Europe; However, in China, there are a large number of users for various crackers and plug-in software. As long as these software do not violate the user's system and data, the security software will not report the virus; In addition, av-c and other traditional anti-virus evaluation are based on the known virus samples, and the sample selection is also more inclined to the viruses prevalent in Europe
"obviously, the domestic anti-virus version is not suitable for foreign evaluation such as av-c. If we take part in the test with the domestic common user version, there will be a huge deviation between the evaluation results and the real ability of the proct, which can not reflect the real protection ability of the proct. " 360 said in response
on May 2, 360 issued a statement again, pointing out that "the difference in this event is a dispute between traditional antivirus and cloud security evaluation standards", "360 free security internationalization touches the interests of traditional antivirus instry", "av-c traditional evaluation standards are far away from the real needs of users"
"av-c's traditional anti-virus testing method has fallen far behind the era of cloud security. The two sides can't reach an agreement on the evaluation standard, so 360 decided to withdraw from av-c evaluation." 360 said in the statement
Tencent: it has not violated the evaluation regulations and will protect its legal rights
however, in the face of accusations from international security evaluation organizations and revocation of certification and awards, Tencent's response and attitude after the incident are not the same as 360
on May 6, Tencent said in its statement: "we regret to see that AV test, the evaluation organization, issued an announcement questioning the optimization of the test by Tencent's computer housekeeper procts. However, at the same time, we have also been confirmed by av-c and other well-known evaluation organizations that e to the use of comprehensive performance testing methods, Tencent computer housekeeper has no problems in their tests, and the existing achievements will not be affected, and Tencent security procts will continue to be tested. "
the relevant person in charge of Tencent told reporters at the rule of law weekend that in fact, in the statement jointly issued by the three evaluation agencies on April 30, it was clearly pointed out that there was no problem with Tencent's computer housekeeper procts
"three evaluation organizations have just confirmed that we have no problems, but AV test issued a statement on May 5 accusing us and canceling our certification and awards; The emergence of these situations makes us confused about the current situation of different evaluation standards. " The relevant person in charge of Tencent said, "we don't agree with AV test's cancellation of computer housekeeper performance. In view of AV test's unreasonable cancellation of Tencent's computer housekeeper performance, we require AV test to correct it. At the same time, we will safeguard our legitimate rights and interests through legal means."
however, despite the confusion over the different evaluation standards and the disagreement over the cancellation of the results, the relevant person in charge of Tencent said in an interview that they would actively communicate and solve problems, seek consensus with an open mind, and welcome all fair and just international evaluations
"it is very meaningful for us to understand the real level of our procts and see our advantages and disadvantages by participating in the safety evaluation of international authoritative organizations." Tencent relevant person in charge said.
