Picture of setting a4620m miner

1. This does not need too many settings, the best graphics card to use NV graphics card 2, the system win10, the power supply is sufficient, the latest version of the motherboard BIOS, the BIOS settings for the main graphics card to PCI e

2, the hard disk must be GPT format, the system must be 64 bit, UEFI does not support 32-bit system

note: UEFI can boot x64 system on MBR disk, but it needs special settings

3. The traditional MBR partition only supports 2.2t hard disk, and the hard disk larger than 2.2t needs GPT, and the BIOS supports opening the integrated graphics card (which can be set) to double display

However, Qicaihong does not have the motherboard of h81-a. h81-a is an ASUS brand and can not support six graphics cards

select factory settings in BIOS, press enter to save and exit, then discharge the main board COMS, and then enter BIOS to set

{rrrrrrr}

extended data:

seven rainbow motherboard boot into BIOS method:

1, you can press del key to enter BIOS

2. You can boot the BIOS directly without connecting the hard disk

there are two conditions for supported graphics cards:

1. Several graphics cards are supported in a few slots, and the expansion slots of ciex1 and pciex16

The main board power supply and power supply are enough. When most motherboards are turned on, you can enter the BIOS interface by continuously pressing the "del" key. Some notebooks can only enter the BIOS interface by pressing F2

BIOS is not only the basic input and output system of computer motherboard, but also the basic system of communication and recognition between computer hardware

contents include: power settings, hardware on / off, hardware working mode settings, overclocking, etc. The contents of bios are in English. Now some brands of new motherboards support Chinese. The options in BIOS can't be set randomly without understanding its specific function, so as to avoid the computer can't boot normally

its main function is to provide the most direct hardware setting and control for the computer. In addition, BIOS also provides some system parameters to the operating system

the change of system hardware is hidden by BIOS, and the program uses BIOS function instead of directly controlling the hardware. Modern operating systems ignore the abstraction layer provided by BIOS and directly control hardware components

BIOS Setup program mainly manages and sets the basic input and output system of the computer to make the system run in the best state. Using BIOS Setup program can eliminate system faults or diagnose system problems

2. Today's computers have the function of energy saving and power saving.
the motherboard will detect the CPU temperature to control the optimal speed of the fan.
when the CPU temperature is high, the motherboard will control the fan to rotate at high speed.
when the CPU temperature is low, the motherboard will control the fan to run at low speed.
for energy saving and noise rection.
your CPU temperature is only 37 degrees, so the speed is normal

3. CPU temperature is not high, very normal
if too much ash enters the CPU fan shaft, it will not rotate too fast, and sometimes there will be a lot of noise.
suggestion:
remove the CPU fan and clean it
you can also use a syringe (or a small piece of paper) to inject some oil (is there no oil? Vegetable oil is OK, it's better to use butter.) take care not to use too much
repaint your CPU with cooling paste! The quality of a fan lies in its heat dissipation. If it doesn't work, replace it with a fan
hope to help you!

There are several possibilities for the low rotation speed of the CPU fan when starting up:

< UL >

the fan is controlled by the CPU temperature. Usually, when the computer starts up, it runs fewer programs, so the temperature of the CPU is low, and the fan runs slowly

The fan has accumulated st. At the beginning of operation, the speed of the fan is slow because of the larger friction caused by the ash deposition of the fan. After a period of operation, the st will fall off e to the operation of the fan, and then the fan will operate normally. This can be opened to check the chassis, you will know

in addition, the fan is permanent, and because of the high ambient temperature, the lubricating material on the fan bearing will dry up, which will also cause the starting speed to be slow. However, this may be accompanied by mechanical noise. If you look carefully, you can judge

5. It doesn't matter, AMD's CPU is basically like this, the fan doesn't need to be replaced, it will consume more power, it won't affect, and there is more heat dissipation, everything else is OK. Mine is AMD's
4400 +
, which is worse than yours. The original one doesn't move

6. What software do you make have problems? Your parameters are not normal

7. EVM is an expansion slot to increase the density of TDM interface. This slot utilizes pvdm on the motherboard to provide higher density for analog and basic rate interface (BRI) voice interfaces
