Blue screen of mining machine with 4 graphics cards

1. Your motherboard to support four graphics cards, generally can only support three
in addition, if your hard disk is m.2 SSD or U2 interface, inserting the fourth graphics card may occupy the hard disk's PCI bus, resulting in hard disk unreadable.

2. 1. To detect whether the power supply is fully connected and whether the power consumption is enough, it needs to be used with brand power supply with high power consumption and good quality
2. For the specific model of the motherboard, it is recommended that you consult the manufacturer's technology, and under the guidance of customers, you may need to brush the latest BIOS file.

3. Generally speaking, press the three keys of Ctrl + Alt + delete
the specific operation methods are as follows:
1. Judge that the machine is in a dead state. The way to change the state is to press the NumLock key to see if the num light will change the state with the pressing of the key. If it doesn't change, it will be in a crash state
2. If the machine is in a dead state, press the CTRL and ALT keys with your left hand, and then press the delete key with your right hand while keeping pressing
3. The system will restart.

4. There should be a conflict between hardware or between hardware and software. If the memory is loose, try changing the slot. Sometimes the virus will cause blue screen.

5. Now there are special mining boards
expansion slots for mining boards: 1 PCI Express x16 slot, 5 PCI Express X1 slots
support the installation of 6 graphics cards

6. 1、 There is an oil indicator cover on the top of the instrial lock. Just screw it down and fill oil directly. Then there is an oil indicator window in front. The oil level should not exceed the second oil level line< (1) always refuel


all oil holes on the machine and all rotating parts should be refueled with clean sewing machine oil every 4 hours. Other oils and unclean sewing machine oil should not be used, so as not to affect the service life of the machine
(2) regular maintenance and inspection
it is necessary to keep the parts clean, regularly check whether the temperature and sound of the rotating parts are normal, and repair them immediately if any problems are found, so as to avoid damaging the machine
generally, minor overhaul is concted once a month, and cleaning and major overhaul are concted once a half year. After being put into use for a long time, it should be cleaned and overhauled first
the thickness and use speed of the sewing material should be selected within the specified range, and it should not be overloaded or over speed.

7. I think the power supply is small. Are you six of the same graphics cards? According to the full load of 350W, six power sources should be more than 2000W. Crash is a sign of insufficient power.

8. Power supply is insufficient or PCI-E does not work, it is recommended to dig
pay close attention to digging now. If it's too late, it will be devalued. Otherwise, even the electricity bill will not be enough.

9. Now we use lead-free welding, the welding temperature is generally about 400, these four capacitors are dropped in use, which proves that there is something wrong with the power supply part of the graphics card. We need to check the repair welding components first, instead of not welding several capacitors alone
if the solder melts, it is recommended to check whether there is tin connection, burning loss, overlapping or dislocation of components in the circuit, and repair the capacitor after correction and inspection
in addition, the soldering iron should be white light or the shell and welding head should be grounded. Prevent static and inctive electricity from damaging components. Special through-hole device or solder should be used to avoid damaging the pad and wiring. Through hole should be properly filled with tin, so that it is easy to through hole.
