The miner has only four 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. mining machine
needs higher computing power, not the performance of graphics card. AMD and NVIDIA have the same price of graphics card, amd has higher computing power, so mining machine uses this kind of graphics card more, I hope it can help you

4. 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

5. The power on time is too long. It is estimated that the contact is poor. Remove it, rub the golden finger of the graphics card with the eraser, and then test it one by one. No problem. It's all plugged in.

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.

That's the mainboard of the miner. It's for mining. It's not easy to make a computer. CPU is basically slag, many are integrated CPU. There are enough graphics cards now. The performance improvement of crossfire technology is limited. Even four of them have money to burn. The medium and high-end graphics cards fully meet various requirements. The picture below is a miner motherboard. CPU integrated. In addition to mining waste, a

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. This is what Tianhe-1 and Tianhe-1A do.
Tianhe-1 uses 6144 Intel general multi-core processors and 5120 amd graphics acceleration processors, with a total memory capacity of 98tb. The bandwidth of point-to-point communication is 40Gbps, and the total capacity of shared disk is 1PB. The supercomputer system will be deployed in the National Supercomputing Center in Tianjin Binhai New Area as the business host. Tianhe-1 adopts AMD's ati4870 and Tianhe-1A adopts NVIDIA chip
