Zhenhua 1300W mining

1. A little suspended, three card 780 is 750W, full load is higher, you want to match the miner? That must be full load. 1000W is a bit suspended
the standby power of the processor is 130W, as well as the hard disk and motherboard, so 1000W is a bit suspended, which is better than 1200W

for example, the 1275w of TT toughpower XT layout (tpx-1275m) may be enough

2. This problem is quite complicated! Building owner

"when the graphics card is plugged in, the power on display does not reflect and does not display, and there is no alarm. If you change the graphics card, you can turn it on." from here, the graphics card should have no signal output
I think the following article should be OK
many video card players like to swipe their DIY BIOS, but they are afraid of the black screen after the swipe failure. After the failure, it's a nightmare for DIYer to either hit blindly, recover, or find a PCI graphics card to help. In fact, there is a way that you can brush BIOS with little risk

DIY principle: some are like double BIOS. If one of them is damaged, the system can read the correct BIOS information of the other
but where can we find a second BIOS?,, Hehe, isn't there a motherboard
DIY idea: 1. After the host starts, the first BIOS data loaded is the graphics card, and then the motherboard. Then there is CMOS data. If the BIOS data of the graphics card fails, the screen will be black, but the system is still running. So if the BIOS of the original graphics card is embedded in the BIOS of the motherboard, the system can boot Beiqiao twice and call the hardware API of the graphics card correctly. At present, the BIOS part of the integrated graphics card on the motherboard is embedded in the motherboard BIOS, so this method is really feasible
2. Brush the BIOS of the graphics card into the BIOS of the motherboard (check the model and capacity of your motherboard BIOS, which is generally 1m, and some motherboards may have 2m.4m). If the motherboard BIOS has enough capacity to install the BIOS file of our graphics card, we can completely install it
DIY tools: 1. BIOS patcher (the previous version was in DOS environment, and it may be a little troublesome for colleagues with poor e-writing. I don't know what version it is now. When I used to use it, I only supported the BIOS chip of Edwards, but now I probably support it all)
2. My main board BIOS brush software
3. The use of BIOS patcher: http://www.yesky.com/299/1711299.shtml

DIY Method: export the BIOS of the original motherboard first, Open the BIOS file with BIOS patcher, put your backup BIOS file into it, and then save it For a 1m capacity BIOS chip, the bios.bin of this kind of motherboard is only 512k in size, and it's OK to add a 256K graphics card BIOS)
if the size of the saved motherboard BIOS file exceeds the standard, the motherboard BIOS embedded with the graphics card BIOS may not be able to brush into the IC chip. Don't be afraid, we can use the BIOS patcher to delete some useless things in the motherboard BIOS, Free up some space for the graphics BIOS. What can be deleted? Someone has tried to find related posts. I dare not try, should be the motherboard BIOS brush broken, only into the hospital.. This is the last resort and the most risky link. If this problem occurs, you can choose to give up after weighing I can only blame my motherboard BIOS chip for being too small  A  F7C  H - when the motherboard BIOS with graphics card BIOS completely meets the requirements, we can go to the next step and brush the finished motherboard BIOS file as motherboard. The computer reported that the personal door was OK. Now our lifebuoy is ready. Now there is a spare BIOS on the motherboard, so we don't worry about the black screen after the failure of the BIOS
0use: when we're done, we can brush the BIOS of the graphics card.. For example, if you want to brush the miscellaneous graphics card as asus's, if you find that after refreshing, the system displays the same BIOS as before, that is, there is a problem with the BIOS of asus's graphics card, it can't be loaded, and the lifebuoy works. The system is currently using the standby BIOS on the motherboard. No black screen e to the failure of refreshing the BIOS of the graphics card. Is it very sci-fi to continue with the BIOS of the DIY graphics card?, No, it's true. This is really a once and for all method,
reverse thinking, we can brush the BIOS of the DIY graphics card into the motherboard, and then short circuit the BIOS chip of the graphics card. Can ensure that the graphics card is not bad, (for everywhere borrow sample graphics card to fever JS is feasible), but this road seems to be n times higher risk factor, so stop

PS: we can pre DIY the BIOS of the graphics card to be embedded in the bios.bin of the motherboard, and add a sentence under the post character to remind you that the embedded BIOS is currently used, which is convenient for us to distinguish from the BIOS of the graphics card
this method can only ensure that the graphics card with damaged BIOS can work normally on its own machine, but if the BIOS of the graphics card is not repaired, it can't be used on other machines, which is why you need to add a self-test prompt to the standby BIOS, so as not to forget that the BIOS of the graphics card is damaged by DIY and hasn't been brushed back.

3. The graphics card is broken, isn't it guaranteed by the manufacturer? Generally from the date of purchase to the 1-year or 3-year warranty period, if you can get your graphics card in the warranty period, you can send it to the shop where you bought the computer for repair. (in the warranty period, it should be free of charge). If the warranty period is over, you can also get it to the shop and ask them to send it to the factory for repair (charge some fees)

4. Already started, Zhenhua tonghuang 450W bronze certification, better than Antaike VP series

Maintenance ideas of graphics card

black screen

1 cleaning: use rubber to clean golden finger. The entire graphics card is grayed out. This is a necessary step

2 visual inspection: carefully check the front and back sides of the graphics card for false soldering, damage and detachment of components, and whether the signal wiring is broken or twisted

3 detection: use a multimeter to detect the power supply FET of the graphics card and the control pole element of the FET. The power supply component of the graphics card control chip

4 power on to measure the voltage: measure whether the voltage of power supply field effect transistor, control chip, BIOS chip, video memory, main chip of video card and power supply point is normal

5 clock: A: whether the clock signal of the AGP slot of the motherboard is sent to the graphics card
b: whether the Jin Zhen on the graphics card is normal, and whether the chip capacitance and resistance connected to the Jin Zhen are normal

6 reset: A: whether the reset signal of AGP slot on the motherboard is sent to the graphics card
b: brush the BIOS chip on the graphics card

6. Unknown_Error

7. 1. If the graphics card in semi disabled state is not completely broken, the symptoms are as follows:
it can be turned on normally, and it can use small software normally, such as office, and it can also surf the Internet normally. In a word, there is no problem with general basic operation. But once "full" hardware acceleration is used, the screen will turn into a flower or color screen. Or when playing games, the speed becomes slower or the screen becomes colorful immediately
generally, the graphics card is about to be damaged. When it is not completely damaged but in a semi disabled state, the hardware equipment will have such a situation: the capacitor on the graphics card is protruding or can smell the smell of burning. Or, the trace of the circuit is fuzzy, and the interface is loose
2. Completely damaged graphics card
when the graphics card is completely damaged, the computer cannot be turned on normally. When power on, you will see the display screen prompt "no signal" and other words
symptom summary:
1. The computer monitor doesn't respond, the screen is completely black when it is turned on, or there is a beep
2. The display color is abnormal
3. Crash
4. There is a splash screen in windows, and the handwriting can't be seen clearly
professional tools are needed for the maintenance of the graphics card, and non professional personnel are not recommended to repair it by themselves. Or replace it with a new graphics card
- for reference

8. What are the symptoms of the computer when the graphics card is broken?
as long as you are using the computer, you will know that the graphics card is an important part of the computer, and its importance is self-evident. If the graphics card is broken, the first thing we think about is the picture on the monitor, then what are the symptoms of the computer when the graphics card is broken? The following small series to tell you about the graphics card broken computer performance of some symptoms, so that you can find the right solution
the function of the graphics card
to know the symptoms of the broken computer, first of all, let's understand the function of the graphics card
the full name of graphics card is display interface card, also known as display adapter, video card, video adapter, graphics card, graphics adapter, etc., which is the most important part of the computer. It is the equipment of digital to analog signal conversion, and undertakes the task of output display graphics. It is a "bridge" between the host and the display. It controls the graphics output of the computer, processes the image data sent by the CPU into the format recognized by the display, and then sends it to the display to form an image< If the graphics card is not completely broken, the computer will show the following symptoms:
1. It can normally start up, surf the Internet, use small software (such as office) and other operations, and the general basic operation is no problem. However, if you use the "full" hardware acceleration or play games, the computer will slow down, or the display will be full screen. Even if you re install the driver of the graphics card, you can't solve the problem of slow speed or variegated screen
2. In general, when the graphics card is about to be damaged but not completely damaged, the hardware equipment will have such a situation: the capacitor on the graphics card is protruding or can smell the smell of burning. The circuit is fuzzy and the interface is loose
2. The graphics card is broken - completely damaged
when the graphics card is completely damaged, the computer can't be turned on normally. When the computer is turned on, the screen of the display will prompt "no signal" and other words. In this case, we can change the graphics card directly
2. The symptoms of the graphics card breaking down the computer
1. The computer monitor doesn't respond, the power on screen is completely black, or there is a beep, which belongs to the completely broken graphics card
2. The display color is abnormal and the picture is very fuzzy. As shown in the figure:
3. The computer often crashes
4. The display shows a splash screen, illegible handwriting, color change, incomplete display, and some abnormal vertical lines or irregular small patterns
5. There is garbled code on the screen when starting up
6. You can enter the computer and always prompt that the driver of the graphics card is faulty, which leads to no display
the above are the symptoms of the computer when the graphics card is broken. Generally, the problems of the display screen are basically related to the graphics card, but they are not absolute. Sometimes, the same symptoms will appear when the memory is loose or damaged. When we encounter such problems, we should first rule out the causes of the memory and consider the graphics card.

9. A good stand-alone graphics card needs a rated power supply of 600W.
