Hello everyone, in this lesson we will talk about cheats in discrete graphics cards

2

00:00:05,700 --> 00:00:08,900

The gold finger is actually just a plug-in connector,

3

00:00:09,566 --> 00:00:13,333

mainly used to connect the motherboard and graphics card

4

00:00:14,200 --> 00:00:20,666

From the circuit point of view, the golden finger is mainly used to transmit the signal between the CPU and the GPU,

5

00:00:20,866 --> 00:00:23,466

and to supply power to the graphics card.

6

00:00:24,400 --> 00:00:28,966

There are two kinds of power supply on the golden finger: 12V and 3V

7

00:00:29,600 --> 00:00:34,566

The signal line has PCIE bus, reset signal and a pair of SM bus

8

00:00:36,133 --> 00:00:40,833

It's just that this is not used for some graphics cards on the SM bus.

9

00:00:40,900 --> 00:00:45,500

We also need to know that gold fingers generally have two sides, AB and AB.

10

00:00:46,033 --> 00:00:51,133

The side with the GPU is side B, and the side with the backplane is side A

11

00:00:52,733 --> 00:00:55,399

We then observe the golden finger, we can see that

12

00:00:55,733 --> 00:01:00,466

the golden finger is divided into a small section and a long section

13

00:01:01,200 --> 00:01:07,433

The order is the number of directions from the small segment to the long segment

14

00:01:08,133 --> 00:01:10,733

Here is the first pin

15

00:01:11,366 --> 00:01:15,066

Suppose this side is B side, then the first pin is B1

16

00:01:17,966 --> 00:01:20,700

The small segment has a total of 11 pins

17

00:01:21,200 --> 00:01:24,533

The last pin of the small segment is B11

18

00:01:25,600 --> 00:01:29,533

And the first pin of the long segment is B12,

19

00:01:30,000 --> 00:01:33,000

and so on for the rest of the pins
