On August 14, 2009, I wrote this passage in my QQ space:
This passage was used to describe the feeling that I just wrote the above article is perfectly relevant. After I finished writing, I sat on the side and felt the full warmth and sweet scent of the thread. It was also rewarding. With a sincere blessing, I think this is the driving force behind my second series of articles.
Time backtracking, turning up the photo wall in the group PHOTO, full of memory paving, mining machine and video card in the history of my struggle are more important part, so for the graphics card I think I have more complex express.
The first part, ten days of brotherhoodHowever, when I started playing Bitcoin, I didn't have high-profile Li Xiaolai, no ASIC miner, or even a formal trading platform, not to mention a variety of derivative industries.
When I was like a cocoon, I opened up a small space at home and assembled a high-end video card that I would never buy. From one card to two cards, I constantly went through various tossings, digging out coins and selling them. , change equipment, and then dig. At that time, it was not possible to return to the current issue, nor did I think of such an earth-shaking thing. I just felt that "the machine can earn a small amount of money without anything to do. It is very good."
For individual miners, especially those who have already begun graphics mining in the early days, the video card mining machine is actually a hobby, just as women like various brand-name bags, and when they see interesting digital products, men are always unable to hold their curiosity. What's more, this is a digital product that can be used to make money. There is a very interesting interpretation of men's love of electronic products, women like the inner mentality of clothes bags: men like hard things, women like soft things. When the then-professional mining machine is really a purely gambling profit, there is no half-dollar relationship.
The impression made by many people of AMD's graphics cards is that they have high fever, high power consumption, high cost performance, and many mine cards, which are risky. Let's take a look at the A card today. For A-card, he once bought a lot of mines, so he has a lot of experience with A-cards.
Timeline: August 2012
2012 is a very simple video card mining era, this is a record of my Taobao transaction, and later there are a number of offline transactions are also a lot, do not think that all my cards, I only have a few, the rest are familiar with I commissioned my purchasing because there is a power mine near the local area that can host the video card mining machine, so many of my friends commissioned my purchasing service and stuffed them into nearby mines to mine Bitcoin.
What was the concept of the mine at that time was this concept. . . . . . All streaking, several graphics cards plugged into the motherboard, so naked, each mining machine access to a network cable, with a computer to open TEAMVIEW for remote management, graphics, CPU, power fan noise accompanied by the heat issued by the graphics card, In this way, day and night production, when the mine owners sometimes do not know the video card will allow me to debug the past, I think I can basically help out, because I understand that after the removal of electricity bills, there is little left, and then at the time Mining is a bitter b live, do not look at a graphics card mine owners can not earn a few money, so I am free to debug for him to pay more than a friend. At that time, mining wasted huge amounts of electricity and human resources and could not earn any money. Instead, it upheld the stock price of AMD at that time.
I almost forgot the price at that time. Later, I found a friend's MAIL, only to think of a 80-100 BTC in early 2013.
However, as far as this old friend's email is concerned, his prediction is completely correct. If his Bitcoin can be saved to the present, it is estimated that it is also worth tens of millions of people, but at that time to maintain the computing power of 10G is not simple, a HD5850 in the mining software CGMINER reflects the computing power of about 325M, to Maintain 10G computing power to get 30 5850 to do, don't underestimate 30 5850, a card's power consumption in the vicinity of 200W, 30 5850 plus the motherboard CPU how these one hour at least have 6000W, is 6 degrees Electricity is 144 kWh in 24 hours and 4320 kWh in one month.
I remember that at that time, there was basically no A-card sale in the store. As long as there was a local tyrant to package the clearance, so for A-cards, people often go to the yard or the factory to drag and drop goods. A lot of A-card agents are the basic shelves. Very big, spectrum is also very positive, the relationship is not good to ignore you, you can hardly imagine that you want to go to a so-called Sapphire to buy video cards, but also invited him to eat, but also responsible for KTV nightlife and the like at night Consumption, the price of the graphics card or how much he said. . . . . . So people who want to dig the graphics card to desperation only to the Internet to collect the card, or in the use of graphics cards between enthusiasts come back, but the graphics card mining LTC this wave I really did not catch up.
May 2013
The ASIC mine machine that my neighbor and I put into place, begin to enter the stage of high-speed accumulation
October 2013
At the end of 2013, my neighbors and I basically decided to withdraw from the Bitcoin industry. After I bought the house, I wanted to concentrate on the family. I was obliged to retreat from the virtual currency group because I had the experience, and I would chat with my friends in the computer group. Chat products and technologies.
One day, a co-founder helmet of the raincoat miner gave me a call and asked me what I would like to know about the PTS stocks. I said that I basically need to fade out of the mining industry now. What else does he do? This friend is also very real. He said that if you look at it and see if there is a possibility to make a wave, anyway, you will study and research how to tap it. At that time, I told the Shenzhen brothers Jianwei and the local mine owners about this issue. I said that it may be an opportunity like the Bitcoin ASIC mining machine. You have two rooms and no cars. Under proper research, can you check? Waiting for an opportunity to turn around is the same as when I was Bitcoin ASIC miner.
Popular science link: Bit stocks are PTS at first, claiming to be CPU mining, but then broke the graphics GPU mining tool, and before this tool software broke, we have already got it in advance, that is, theoretically possible The official team began mining with video cards and competed with CPU mining. Everyone should be aware that GPU and CPU are not a difference in magnitude, so theoretically it is possible that the official team holds a large number or even a large part of the PTS and it is highly probable that all of them have been cashed out. So if you have to say Bitcoin is a technical scam, then the bit stock is a pure Ponzi scheme. And the opportunity for my intervention is 0 cost.
November 2013
On November 5th, Kinwell came up with a phone call and told me to quickly find a few computers to install the PTS wallet that he sent to my mailbox. Do not hesitate immediately, you can SOLO mining, but only CPU mining. I immediately called my neighbor Lao Zhao and asked him to put all the computers together and wait for me to debug.
I was at home with two computers, an I7 2600K, and an I7 4930K. So when I was completely on, I immediately went to the neighbor’s Lao Zhao’s house to help his three I5 hosts open the program to dig the PTS.
I took a photo display: On November 5th - November 8th, I dug almost 700 days. The neighboring Lao Zhao also digged 400 for three days. He even drew down a cybercafe to dig PTS, probably digging more than 8,000. One, mine board probably dug more than 4,000, in fact, there is no price reference for this stuff at that time, so when you warm up entertainment and entertainment, did not put too much thought. Since November 9th, the difficulty has greatly increased. It has been difficult to find SOLO in blocks. If a block could have been digging, 50 PTSs have been collected. The result was 47.5 minutes without digging for two days. In the following days, the world’s super calculations The center intervened and opened a large mine pool. It was very difficult to dig into blocks. It was only possible to dig into other people's pools. But fortunately someone started to collect PTS, and from the very first 5 cents to 5 yuan. After another 10 dollars, after a few days, the mine owner called for someone to pay for the graphics card mining program, you can dig the card, double the efficiency, I said I do not have a graphics card, then a GTX570 A use of a HD5850 tube, the mine owner said a word that touched me so much: Come here and move a box of 290X to dig it. I'll lend it to you. I'll be back if I don't have it.
I’m not at all polite. I’ve just gone straight to him and picked up a box and got a new one.
After I had 5 cards on 2 hosts, the remaining 5 cards asked neighbor Zhao whether they wanted to. The mine owner gave the GPU graphics mining program faster than the CPU. Lao Zhao said to me, I directly passed him to install and debug.
No two days later, Zhao Zhao slammed a box of HIS 280X and said he would. . . . . . drunk.
I said that no computer can be used to hold the video card. Zhao said that he had to move two sets directly to his home. He only installed eight high-end I7 4930Ks, and he also had his card installed. I say it!
I just bought my new house with my hand, and both of them were polite and turned into mines. . . . . .
On November 16th, my PTS wallet received 1,058 PTSs.
After the GPU mining PTS program was publicized, it basically did not find anything. When I was liquidating these PTSs, they were in batches. I sold them on average around 90 yuan. Some of them sold more than 100, and some of them were devalued after converting BTSx, but they always made about 10 W. Looks like it was busy for ten days before and after.
ending:
Jianwei packaged Internet cafes and university computer rooms to dig PTS, and finally settled RMB 3 million. However, it is also considered salted fish turned over.
The mine owner eventually reportedly earned more than 800,000 yuan without liquidating the equipment.
The neighbor Zhao and I are similar.
But the most daring people directly spiked our IQ. Someone directly rented out the grand cloud computing server at that time. As a result, hundreds of thousands of PTS were dug overnight, and it was really a night of riches. Therefore, the virtual currency industry is the relentless plundering of the wealth of other non-professional participants by technology and knowledge owners.
In fact, I sometimes feel that people get along with people is really fate. If it weren’t for the PTS project I introduced to Jonway, he would not prompt me to promptly intervene at a crucial moment; if it wasn’t when I was in trouble at the time, I would debug the video card miner for free and ask him to intervene at the right time. Maybe I There has been no graphics card and GPU software used in advance; if not my neighbor Zhao Zhao timely intervention and sub-card to him, I may not have the host and the late graphics card. Therefore, people and people are truly mutual. True brothers are really friendly and money is not the key. This mutual friendship helped me achieve ten days and 100,000. The money may not be too much, buy the article cover that bunch of GTX1080 estimated enough, but this friendship allows us to maintain a very close relationship today, and projects always take care of each other.
Finally, once again, do not step into this field. After the BTSx has been redeemed, the bit-stock PTS reaches its peak, and at the same time it has also started a long downward journey. During this period, it may be that the development team’s own coins are not enough, and the multi-currency The merger of BTSs, in fact, superfluously disguised, and giving themselves more money, which also accelerated the people's confidence in the collapse. Bit stocks have so far been low, and they have now withdrawn from the top ten of the market value of electronic currency circulation. But you can make more than a few close friends, and it is a matter of time before the three or five friends make a mark. So you have to say that one's greatest asset is a friend.
Here's a side note: About Mine Card
My suggestion is not to buy mine cards, but how do mine cards differentiate?
The first is the model : the mine card is basically locked inX 280 280X 290 290X due to computational power and cost performance. Buy second-hand or above graphics cards need to pay attention to whether the mine card. The later 380 380X these products and higher 3 series products are unlikely to have mine cards, because these are the products released after the mining myths are destroyed and can be purchased with confidence.
The second is the back core :
The PCB on the back of this card's core is yellow, and it is basically baked with high voltage and high temperature. See this video card please stay away.
The core on the back of the A card that has not been mined is not yellow. Please note this.
The second part, the public version of the plotThe first section WHY?
I have a serious public version of the graphics card, regardless of the A card N card, when I selected the card, mining my preferred version of the public A card, but not so good, A card version of the popular, coupled with mining incentives , it is hard to get the public version; but for personal use I will try to choose the public version of the N card.
The difference between my opinion and DuMian is:
I think the public version of the graphics card is a complete industrial design product, including circuit, PCB, IC, chip, video memory, and heat dissipation. All of them have passed the usual laboratory considerations and tested and released a SAMPLE to explain GPU features.
So why is there a non-public version?
1, non-public shrink water
Because CUT DOWN will generate huge profits, save costs, and in the face of huge market competition pressures, only cutting can effectively reduce costs.
2, non-public and non-public high frequency version
In fact, we see most of the graphics cards in the market are ordinary versions of non-public version, Asus Eagle Knight, MSI's GAMING, HIS's ICEQ are all such products, the general version of the non-public version of the design is not intended for castration, but because The existence of the production lines of major manufacturers requires some solutions. For example, HIS's ICEQ or MSI's GAMING graphics solutions, this series of PCB and IC including radiators are fixed procurement, the supplier signed With the long-term supply contract, all the production and supply of this product series is perfect, and it will not be available for lack of IC or PCB. As long as the order is placed, it can be quickly produced.
However, this is not the case for the public version card. Each version of the public version card will not inform the downstream manufacturers in advance. Which IC do I plan to use? Which type of PCB do I plan to design? Which type of heat sink do I customize, such as GTX980 and GTX1080? Edition, the difference is very big, from the radiator to the material is also very different, if which company tries to produce the public version of the GTX980, then when he goes to the production of the public version of the GTX1080, the production line will have to re-arrangement, procurement of materials Re-signed the supply contract, from the timing of the release of the graphics card to occupy the market layout to the loss of excessive manpower and material resources are enormous, for the graphics card manufacturers are outweighed, generally after the core of the graphics card is set down, the downstream manufacturers began to address The design of their own series of products, this can ensure the highest timeliness of release and the fastest production efficiency, small changes in the production line, the same material or fine-tuning can mass production of graphics cards.
But can non-public and high-frequency versions achieve the stability of the public version of the graphics card? See how to interpret this question
1. If you just play games casually, non-public version of the card may be more suitable for color, look more beautiful, fans are more silent, the frequency may be slightly higher than the public version of the graphics card. It really does not make much difference.
2. If you want to do some professional use, such as GPU CUDA operation or STREAM operation (mine mining), the stability and compatibility of the public version of the graphics card will be revealed. For mining, a simple CGMINER software The number of non-public versions of deaths is definitely far greater than the number of public editions.
Mining overclocking: The public version card is the only choice, overclocking frequency high pressure is simple and stable.
Operational stability: different design concepts, the design of the public version of the card is not only for the civil game market, while the public card design also takes into account the professional card market such as FIRL GL, QUADRO, TESLA and other professional graphics card market, so their original product design At the same time taking into account the needs of all aspects, you will see a heatsink and PCB prototype almost completely use the corresponding GEFORCE, QUADRO, TESLA three production lines, and to ensure maximum safety and reliability.
But non-public card is different, MSI GAMING 280X fan I think as long as mining people will encounter it, this card fan is very quiet for the game is very good, but used to run at full speed, not two months The fan will hang off. Therefore, MSI had no alternative but to abandon the original REV 1.0 solution and re-created the 280X of the REV1.2 solution to market. The REV 1.0 card was recovered through the RMA.
Is there a public version of the garbage design?
The answer is yes, HD5970 is.
To be honest, the 5970 is a once flagship product, that is, the graphics card mining machine, the highest configuration is 3 cards 5970, a mining machine computing power of 2G or more, but its status on the high ground was actually destroyed by the destruction of the I Ying Ming, this batch of cards in the mining of CGMINER under the high load needs water cooling does not say, which PLX bridge chip around the exclusion of the chip is very easy to burn, if you can not replace the original factory with a substitute, then this card is more than a basic Month will need to go back for a replacement.
Section II My Public Collection
I personally love NVIDIA and AMD's public cards, including game cards and professional cards. After reading the value of my posts, you can see that I did not get a very satisfactory hardware, will be very conscious to do a loaded SHOW to show their own joy, of course, the public version of the graphics card is no exception.
1, the public version of AMD 270
CHIPHELL once passed the crazy ITX card but it was hard to see.
2, NVIDIA QUADRO K2000
3, NVIDIA GT635
Wonderful Samsung OEM public version graphics card GT635
4, ASUS GTX TITAN plus EVGA backplane
The so-called graphics card is easy to get, hard to find the backplane, EVGA's TITAN backplane I struck for two months, and finally sea Amoy EBAY hand.
Installed SHOW section
