00:00:00,200 --> 00:00:01,066

Hello

2

00:00:01,066 --> 00:00:04,833

Let's learn about PCH model recognition

3

00:00:05,166 --> 00:00:11,766

Intel released a single-bridge chipset in 2009, which we call PCH

4

00:00:12,066 --> 00:00:16,000

The full English name of PCH is Platform Controller Hub

5

00:00:16,700 --> 00:00:21,133

Intel's first-generation PCH product is Intel's 5 series

6

00:00:22,233 --> 00:00:28,133

The 5 series it includes HM55, HM57, QM57 etc

7

00:00:28,666 --> 00:00:33,433

Later, the 6 series, the 7 series and more were continuously introduced

8

00:00:33,566 --> 00:00:35,866

Let's look at the following pictures

9

00:00:37,333 --> 00:00:38,366

The first one

10

00:00:39,266 --> 00:00:41,700

This is an Intel 5 series chipset

11

00:00:42,133 --> 00:00:46,633

Its actual model number is printed on the core of the chip

12

00:00:47,700 --> 00:00:51,500

We can still clearly see BD82HM55

13

00:00:52,266 --> 00:00:54,966

HM55 is its actual model

14

00:00:55,433 --> 00:01:00,566

There are HM57, QM57 and so on in the same series as it

15

00:01:01,066 --> 00:01:03,966

The 6-series PCH was introduced later

16

00:01:05,700 --> 00:01:10,300

The 6 series PCH its model number is also printed on the chip surface

17

00:01:10,666 --> 00:01:14,733

BD85HM67 can be seen on the core

18

00:01:14,833 --> 00:01:17,100

Its actual model is HM67

19

00:01:18,066 --> 00:01:20,733

There is HM65 in the same series as it

20

00:01:21,800 --> 00:01:23,900

Start with the 7-series chipset

21

00:01:24,433 --> 00:01:28,766

The chip model of this PCH is no longer printed directly on its core

22

00:01:29,300 --> 00:01:32,733

It is using a codename "SJTNV"

23

00:01:33,000 --> 00:01:36,100

The corresponding actual model is HM70

24

00:01:36,500 --> 00:01:39,800

Next we take a look at Intel's 8 series

25

00:01:40,600 --> 00:01:45,600

The 8 series PCH, which no longer has any markings printed on its core

26

00:01:46,133 --> 00:01:49,600

Its markings are printed on the edge of the PCH

27

00:01:49,966 --> 00:01:54,166

For example SR17D in the picture

28

00:01:54,300 --> 00:01:56,666

The corresponding model is HM87

29

00:01:59,100 --> 00:02:01,500

Find its actual model by code number

30

00:02:04,766 --> 00:02:07,466

You can find it on Intel official website

31

00:02:08,500 --> 00:02:15,833

The 8 series chipsets including HM87, HM86, QM87 and more

32

00:02:16,400 --> 00:02:17,866

After the 8 series

33

00:02:18,200 --> 00:02:21,166

Intel also introduced the 9-series chipset

34

00:02:21,166 --> 00:02:23,233

But not in notebooks

35

00:02:24,933 --> 00:02:31,700

After the 9-series chipsets, the Intel 100-series chipsets continued

36

00:02:32,200 --> 00:02:36,066

For example the HM170 in the picture

37

00:02:37,100 --> 00:02:39,400

It belongs to the 100 series

38

00:02:40,766 --> 00:02:45,100

It's identified as SR2C4 on the edge of the chip

39

00:02:45,600 --> 00:02:47,233

After the 100 series

40

00:02:47,433 --> 00:02:50,000

Intel launches the 200 series chipset

41

00:02:50,233 --> 00:02:52,066

But not in the notebooks either

42

00:02:53,233 --> 00:02:57,933

Instead, it directly uses the 300 series chipset after the 200 series

43

00:02:58,733 --> 00:03:04,133

Common models of 300 series chipsets are HM375, HM370

44

00:03:04,133 --> 00:03:09,566

Its codename SR40B is also on the edge of the chip

45

00:03:10,666 --> 00:03:15,433

After the 300 series, Intel introduced the 400 series chipsets

46

00:03:16,366 --> 00:03:19,800

Common models of 400 series chipsets are HM470

47

00:03:20,600 --> 00:03:23,566

Marking SRJAU is on the edge

48

00:03:25,566 --> 00:03:32,566

After the 400 series, chipsets such as the 500 series and the 600 series were successively launched

49

00:03:33,333 --> 00:03:36,633

This is the model identification of our chipset
