It's better to come early than to come by coincidence, perhaps because of the influence of Yang Yun's atmosphere, this Xbox360, which has been running continuously for 52 hours under high load, is getting worse and worse at this time.

"The CPU of this host is a cell-level chip made by IBM, and IBM is very good at doing this, so their CPU seems to be fine. The problem lies in the graphics chip GPU, the graphics chip technology of Canada Thunderwind is not as mature as ATI and NVIDIA, they are customized products for Microsoft, it can be said that they started from scratch, we suspect that their technical level is not up to standard, especially the heat dissipation system has a big problem. Fang Jindong explained, touching the shell of the iron box, it was a little hot.

Thunderwind RaWind has only been in the graphics card industry for five years, in the world 90% of the graphics card market is dominated by ATI and Nvidia in the environment, Thunderwind was selected by Microsoft to develop Xbox360 graphics chips for them, but encountered countless troubles in the research and development process, and finally the impatient Microsoft sent engineers to help improve the chip, which was only two months ago GPU out of the factory, and finally finalized!

Yang Zhan heard about this matter, this is not a top secret news at Microsoft, the entire Xbox360 project team cannot be tested because of the GPU drag, and cannot continue to develop it, everyone knows very well.

Yang Yun knew it in his heart, but he looked at Fang Jindong's simple outer packaging iron box, and he really couldn't cry or laugh: "Old Fang, I know that when they sent it over, it was a bare board, I asked you to install a shell, and you installed it according to the image of Xbox?" You can completely let Xiang Tian and them send a designer to design the appearance, and you can directly mold zuò here, not the most exquisite. It just needs to make people want to buy. Do you think that players have the desire to buy a stupid black shell like the current one? ”

Fang Jindong asked strangely, "Huh? Are we going to design the shell for it? Isn't that what Microsoft should be doing on its own? ”

Yang Yun felt that it was impossible to communicate with this tech nerd: "They will definitely try their best to make the appearance right!" Of course, it is delicate and beautiful. Tightly stitched, with a streamlined or angular aesthetic. It definitely won't be what it is now! Now you have a simple and casual cover on it, the tin box has a large space and fast heat dissipation, what's the use? I just want to see how it looks when the heat dissipation is unstable! ”

He said as he pressed the hard shell outside the DVD drive, but he didn't expect to use a little force, maybe the motherboard without a fixed position was slightly deformed, his hand slipped slightly, and the iron box fell on the desktop with a bang. At this time, the CPU fan made a screeching sound, and after a few turns, it completely struck, making a humming sound that could not be stopped at all, and the obvious resonance could be felt on the desktop near the Xbox360.

"Don't panic! Just let it vibrate! Yang Yun stopped Fang Jindong, who was about to check the host, and quickly looked near the power button on the side, and sure enough, the red light on the integrated board could be clearly seen from the gap in the shell.

"See, that's what I want. If no one touches it, if it happens on its own after a long period of high-load work, my purpose has been achieved. Have all these anomalies been recorded? Yang Yun didn't forget to ask this question.

Fang Jindong ran back and forth twice and said, "I've written it down." Mr. Yang. The temperature of the CPU that has fallen into a state of panic is rising rapidly, and the graphics processing chip is dying. It's a bit hot! ”

Yang Yun touched the iron shell, which was the place corresponding to the GPU. It was indeed a little hot, and he motioned to Fang Jindong to open the chassis box. Fortunately, this is just a simple iron package with a buckle jammed, two people work together, one lifts and one takes the buckle, and the Xbox360 shell is removed in three clicks and two clicks.

A wave of heat gushed out,Yang Yun was happy in his heart,Sure enough,Xbox360The design of the integrated circuit board is very unreasonable,Their designers must have only considered the performance of the host,There are indeed a lot of high-performance things on the circuit board,For example, it supports HD1080P,This has made 90% of TVs ashamed,This is completely the rhythm of a high-definition home theater!

But what's the use? It didn't work!

Support IEEE, support digital camera card interface, support wireless Bluetooth function, support network card function, the more functions, the larger the use area of its integrated circuit board, and the higher the power it consumes, once the case protects the case heat dissipation function is inconvenient, this integrated circuit board will sooner or later become what it is now - the red circle crash phenomenon is perfectly presented!

"This fool Microsoft, 800 million US dollars in advertising and 400 million US dollars in research and development expenses, and as a result, I can't even come up with a solution for how to perfectly match such a motherboard and chassis, I can only say that Microsoft is in a hurry." Yang Yun thought to himself, he pressed the power button and let it restart first, wanting to verify whether it could really solve the problem.

Sure enough, the Xbox360 obediently turned off the power and restarted, the speed of the CPU fan increased again, the open shell increased the heat dissipation efficiency of the integrated circuit board, and the Xbox360 started quietly and ran for five minutes without incident.

"Sometimes, it's not enough to hurry!" Fang Jindong smiled and pointed to the monitoring area: "Mr. Yang, I'll explain to you what happened." ”

There is a fault lamp on the integrated circuit board, on the Xbox360 motherboard, the fault lamp near the power supply can intercept the signal of the power supply, CPU, north and south bridges and other key parts, it integrates a current overload protection chip, once an abnormality occurs, the guide zhìCPU and other components can not maintain a normal stable voltage, it will send out an alarm, and maintain the fluctuation of the circuit board components.

"To put it simply, if the CPU is due to voltage fluctuations, due to uneven heat dissipation and the voltage of the north and south bridges changes, or vibration, extrusion and other reasons cause the entire integrated motherboard to fail to operate normally, the overload protection chip will automatically maintain a stable voltage, try not to let the voltage loaded by the CPU change too much, affect the service life of the CPU, or even burn out."

Fang Jindong looked at the number of interceptions just now and explained the consideration of their R&D department: "Because Xbox360 was not designed by us, some underlying things can't be completely dissected for a while, but according to our experience, there are only these few explanations for this situation." ”

Yang Yun nodded, knowing in his heart.

For the Xbox360 red circle crash,Microsoft has never given an exact fault description,All Microsoft after-sales maintenance points are to treat the symptoms but not the root cause,For example, unplug the ground wire interface,Bypass the automatic protection switch,Or increase the heat dissipation power,It can indeed make Xbox360 support for another year and a half,But don't solve the substantive problem,What's the use?

This is a flaw in their own design, but they blame all the problems on other aspects, blaming the voltage instability, isn't it a joke! Expensive, delicate and powerful Xbox 360 is so fragile?

People's ordinary TV is a tractor, your Xbox360 is a Porsche, people drink low-grade diesel and run vigorously, and you drink 100 top gasoline may turn off?

Yang Yun said: "You ask Xiang Tian to send someone over to redesign a tighter packaging box now, the packaging of Xbox360 is definitely not so wide, I dare to guarantee that their heat dissipation effect will not be very good, continue to do testing, I hope to see more frequent crashes!" ”

After leaving the R&D center, Yang Yun found Zhao Yongping again, and if the matter continued, Zhao Yongping would find someone to do those bad ideas and shady black hands.

"Are you so sure?" Zhao Yongping couldn't believe it: "They are Microsoft!" Can a giant in the IT industry make such a low-level mistake? ”

Yang Yun nodded: "Didn't Yang Zhan say it, under the normal plan, Xbox360 should be 2005 to be listed, and now it is a year ahead of schedule, Microsoft's hardware engineers have been working overtime for more than half a year, and they are about to collapse, what kind of efficiency do you think Microsoft can have when working under this kind of high pressure?" Isn't the favorite phrase of Microsoft engineers to put in their mouths 'work happily, work with interest'? They won't be happy working overtime, and they can still expect their game consoles to have a yield rate of more than 99%? ”

Zhao Yongping laughed: "There is some truth in this, I only know that every year Microsoft invests billions of dollars in R&D, 90% of which are useless technologies, and those R&D personnel like to find some bizarre projects." ”

Yang Yun sighed: "In fact, if I have money, I am willing to do it, this model is really good, it can greatly stimulate the creativity of R&D personnel, and it is likely to produce huge economic value." But not now, we need to be targeted, Microsoft can do that, we have to do it with a purpose. That's it, let Wang Zhe and them do it, and a few of you classmates will do it, I can rest assured. ”

Zhao Yongping left happily, Yang Yun was praising them, but there was also a sense of ridicule in it, their classmates of the National People's Congress, Wang Zhe Yang Zhan and a few classmates and junior brothers who were brought out later, I don't know what was going on, the means of doing things were more ruthless than the other, and the one in the shopping mall was called a ferocious, and after grabbing the sore feet of the competitors, he chased and beat him fiercely, and he really kicked to death.

In order to prevent the stock market from soaring and plummeting, the Federal Reserve made a circuit breaker mechanism in 1989, which can temporarily restrict trading with an executive order, and the market index is protected, and the circuit breaker mechanism is also applicable to individual stocks, and Sony's 25% plunge for two consecutive days triggered this circuit breaker mechanism and was protected by the market.

But Yang Zhan and his traders were looking for a relationship in the stock exchange, and they actually wanted to make the circuit breaker mechanism against Sony ineffective, on the grounds that the market index did not plummet, but it still failed in the end, otherwise it is likely that Sony's stock will fall into junk stocks in two days!
