00:00:00,500 --> 00:00:05,966

Hello everyone, in this lesson we will take a look at the use of A card memory test software

2

00:00:06,966 --> 00:00:13,133

A card video memory test software can only measure up to 590 at present, it needs to use the fourth program

3

00:00:14,566 --> 00:00:16,833

And there must be a one-to-one correspondence

4

00:00:17,066 --> 00:00:20,333

between the graphics card model of the A card and the test program.

5

00:00:20,866 --> 00:00:24,066

If it does not correspond, it will directly report an error

6

00:00:24,866 --> 00:00:29,333

After the A card test program comes in, it will enter an interface like this

7

00:00:29,900 --> 00:00:32,600

Let's take a look at this interface

8

00:00:33,400 --> 00:00:37,633

Enter the fourth test program, enter ls

9

00:00:44,666 --> 00:00:47,900

You can see that there are many graphics card models below.

10

00:00:48,200 --> 00:00:52,066

The model numbers of these graphics cards are the test programs

11

00:00:52,666 --> 00:00:58,133

Among them, those with g at the end are test results, and those without g at the end are test programs

12

00:01:00,566 --> 00:01:06,600

For example, 570 is the test program of the 570 graphics card,

13

00:01:06,666 --> 00:01:10,133

and 570g is the result of the 570 test program

14

00:01:10,966 --> 00:01:19,300

Another example is R9255 is the test program, R9255g is the test result of R9255

15

00:01:20,833 --> 00:01:26,966

Which type of graphics card we need to test, just enter the corresponding test program name

16

00:01:27,966 --> 00:01:31,366

For example, the graphics card I plug in now is 580,

17

00:01:31,666 --> 00:01:34,933

let's find the test program corresponding to 580

18

00:01:35,533 --> 00:01:43,866

It can be seen that there are 580 related to 580, 580a, 580ag, 580g, rx580a6, and rx580a6g

19

00:01:51,466 --> 00:01:56,866

They are the results of 3 test programs and 3 test programs respectively

20

00:01:57,733 --> 00:02:02,300

Because the test program of the A card must correspond to the model of the graphics card one by one,

21

00:02:04,100 --> 00:02:06,133

and there are multiple versions of the 580,

22

00:02:06,133 --> 00:02:09,233

and different versions correspond to different test programs.

23

00:02:10,000 --> 00:02:14,566

Which test program to use requires us to test one by one

24

00:02:15,166 --> 00:02:20,000

Type ./580 and press Enter, it will run the 580 test program

25

00:02:21,566 --> 00:02:24,000

It can be seen that he directly reported an error

26

00:02:24,500 --> 00:02:28,700

Directly report an error indicating that it is not this test program

27

00:02:29,100 --> 00:02:31,033

Then let's try 580a

28

00:02:31,600 --> 00:02:33,766

Type ./580a and press Enter

29

00:02:41,933 --> 00:02:44,933

As you can see, this test program can be tested

30

00:02:45,666 --> 00:02:50,333

The test time of the A card is relatively long, let鈥檚 fast forward

31

00:02:59,600 --> 00:03:04,533

Well, after the test is complete it will output PASS or FAIL

32

00:03:04,600 --> 00:03:08,533

PASS means pass, FAIL means there is a problem

33

00:03:09,533 --> 00:03:16,600

If we want to see the result, just add a g after ./580a

34

00:03:21,900 --> 00:03:27,333

Of course, there is no problem with this graphics card, so it did not report an error

35

00:03:27,966 --> 00:03:33,266

This test result is followed by all dots, which means it is normal.

36

00:03:33,566 --> 00:03:38,033

As long as there are numbers, it means that there is an error

37

00:03:38,700 --> 00:03:44,600

The B0 B1 A0 A1 C0 C1 here before, they refer to the channel of the video memory

38

00:03:45,866 --> 00:03:50,900

And this 300 means that the video memory is tested at a frequency of 300

39

00:03:51,500 --> 00:03:55,900

It should also be noted that two tables will appear in one test,

40

00:03:56,233 --> 00:03:59,600

and only if there are no errors reported in these two tables

41

00:04:00,366 --> 00:04:05,200

After reading the results, you can press Ctrl+x to exit the results

42

00:04:05,766 --> 00:04:10,100

The above are the most commonly used operations of A card test software

43

00:04:10,900 --> 00:04:14,466

Next, let's take a look at advanced test commands

44

00:04:15,000 --> 00:04:19,600

Advanced test commands require us to enter a special test program before they can be used

45

00:04:20,333 --> 00:04:26,766

If we want to enter the directory of the test program, we need to enter cd /mods

46

00:04:27,766 --> 00:04:33,533

We enter cd /mods to enter the mods directory

47

00:04:34,233 --> 00:04:42,033

Enter ls, you can see that there are many graphics card models below

48

00:04:44,033 --> 00:04:50,766

The model of the graphics card must correspond to the graphics card one by one

49

00:04:51,000 --> 00:04:58,866

This is a 580 graphics card, so there are three test programs corresponding to 580, 580u1, and rx580a6,

50

00:04:59,300 --> 00:05:04,033

which correspond to different versions of the 580 graphics card

51

00:05:04,233 --> 00:05:07,066

We get into this rx580a6

52

00:05:07,766 --> 00:05:14,533

Enter cd rx580a6 and press the Enter key to enter the rx580a6 directory

53

00:05:15,000 --> 00:05:18,600

The commands in this directory are shown in the figure

54

00:05:21,300 --> 00:05:26,466

Let's look at the most basic commands first, ./cs and ./jg

55

00:05:26,900 --> 00:05:30,000

Enter ./cs to run a basic test

56

00:05:31,533 --> 00:05:35,600

It works the same as testing here

57

00:05:36,000 --> 00:05:40,200

And ./jg is to view the test results

58

00:05:40,466 --> 00:05:44,200

The important thing here is the following two commands

59

00:05:44,700 --> 00:05:49,133

One is the overclocking command, and the other is the switching channel command

60

00:05:50,100 --> 00:05:54,966

The command name of the overclocking command is ./cp plus the corresponding frequency

61

00:05:56,000 --> 00:05:59,866

The overclocking command only overclocks but does not test

62

00:06:00,100 --> 00:06:05,500

After we finish overclocking, we need to enter the test command before we can carry out the overclocking test

63

00:06:06,100 --> 00:06:10,966

Next, let's try the normal test and the overclocking test respectively.

64

00:06:11,200 --> 00:06:13,133

First type ./cs

65

00:06:13,700 --> 00:06:15,800

This is to run a normal test

66

00:06:16,333 --> 00:06:20,800

The normal test time is also relatively long, let's fast forward

67

00:06:26,000 --> 00:06:27,966

After the test is completed, PASS is output,

68

00:06:28,133 --> 00:06:31,133

which means that there is no problem with the graphics card.

69

00:06:31,333 --> 00:06:35,933

Let's take a look at the result, we can see that it reported no error

70

00:06:36,933 --> 00:06:39,533

Let's try the overclocking command again

71

00:06:39,733 --> 00:06:43,566

./cp space plus the frequency to be exceeded

72

00:06:44,500 --> 00:06:47,066

We supercharge it to 2000 frequencies

73

00:06:47,900 --> 00:06:51,000

This frequency is determined according to the graphics card,

74

00:06:51,466 --> 00:06:55,500

which is generally the default maximum memory frequency of the graphics card.

75

00:06:56,900 --> 00:07:02,566

After entering the overclocking command, it will overclock from 300 to 2000

76

00:07:03,533 --> 00:07:08,133

At this time, we will test again, that is, test at the frequency of 2000

77

00:07:08,333 --> 00:07:12,466

Type ./cs and press Enter

78

00:07:22,500 --> 00:07:25,133

After the test is completed, PASS is output

79

00:07:25,666 --> 00:07:27,366

Let's see the result

80

00:07:28,000 --> 00:07:32,833

It can be seen that the frequency of the first two tables is still 300 frequency

81

00:07:32,833 --> 00:07:39,166

That's because the results of the test program of the A card will not be replaced, it will keep adding

82

00:07:42,566 --> 00:07:44,066

We continue to scroll down

83

00:07:46,766 --> 00:07:50,500

As you can see, this result is the result of our test just now.

84

00:07:51,100 --> 00:07:53,566

Its memory frequency is 2000

85

00:07:54,766 --> 00:07:58,366

Next, let's look at the switch channel command

86

00:07:58,800 --> 00:08:01,933

It is ./td plus channel name

87

00:08:02,500 --> 00:08:06,700

Which channel you want to switch to, just enter the channel name

88

00:08:07,133 --> 00:08:11,900

For example, ./td a1 means switching to channel a1

89

00:08:12,466 --> 00:08:17,066

After switching to the a1 channel, all the following operations will only work on the a1 channel

90

00:08:17,200 --> 00:08:22,033

What is the use of the switch channel command?

91

00:08:23,066 --> 00:08:28,333

When overclocking, some graphics cards will crash directly after overclocking

92

00:08:28,766 --> 00:08:31,700

We can't test after it crashes

93

00:08:32,200 --> 00:08:38,100

At this time, we can use the switch channel command to overclock the video memory one by one.

94

00:08:39,566 --> 00:08:42,166

If the video memory is overrun and it crashes,

95

00:08:42,466 --> 00:08:46,200

it means that there is a problem with this video memory

96

00:08:46,400 --> 00:08:48,966

Next let's try the switch channel command

97

00:08:50,600 --> 00:08:52,733

Type ./td

98

00:08:53,600 --> 00:09:00,100

We want to switch to a0 a1 channel, then enter a0 a1 and press the Enter key

99

00:09:00,966 --> 00:09:08,933

You can see that it switched from the B0 B1 A0 A1 C0 C1 D0 D1 channel to the A0 A1 channel

100

00:09:09,533 --> 00:09:13,733

All subsequent operations will only work on these two channels

101

00:09:14,133 --> 00:09:20,266

At this time, we enter the ./cp command again, and then test

102

00:09:31,100 --> 00:09:33,933

After the test is complete, let's check the results

103

00:09:34,266 --> 00:09:36,066

Type ./jg and press Enter

104

00:09:36,366 --> 00:09:39,333

Scroll down to our test results

105

00:09:40,966 --> 00:09:46,600

As you can see, it only measures the a0 channel and a1 channel

106

00:09:46,766 --> 00:09:50,900

And these two channels are tested at 2000 frequency

107

00:09:51,800 --> 00:09:53,800

Let's look at the last command

108

00:09:53,933 --> 00:09:59,666

The last command is to delete the test result command, which is ./sc

109

00:10:00,400 --> 00:10:04,300

Because the A card test program will continuously accumulate test results

110

00:10:04,466 --> 00:10:06,566

After many tests, the results will contain a lot of content.

111

00:10:06,733 --> 00:10:11,400

If you are not careful, you will misread the results and lead to misjudgment

112

00:10:14,600 --> 00:10:21,666

So every time we read the results, we click the delete command to delete the results

113

00:10:23,466 --> 00:10:26,400

At this time, there is no content in the result.

114

00:10:26,666 --> 00:10:31,600

Every time we only look at the latest results, so it is not easy to read wrong

115

00:10:32,400 --> 00:10:35,266

Let's talk about the A card integrated graphics test

116

00:10:35,666 --> 00:10:39,333

The test command of A card integrated display is the same as the test command of independent display,

117

00:10:39,500 --> 00:10:41,766

there is no difference

118

00:10:43,700 --> 00:10:48,566

It's just that there is no test screen for the A card set display during the test,

119

00:10:48,566 --> 00:10:51,100

other than that there is no difference

120

00:10:52,566 --> 00:10:55,766

The above is the use of the A card test program
