00:00:00,566 --> 00:00:06,000

In this lesson, let's take a look at the conditions required for each series of mainboards to trigger

2

00:00:06,666 --> 00:00:12,300

First of all, here are the conditions of the 100 series mainboards that we focused on before.

3

00:00:12,700 --> 00:00:17,333

It can be seen that the conditions required for the triggering of the 100 series mainboard and the

4

00:00:17,766 --> 00:00:21,000

200/300 series mainboard are the same

5

00:00:21,800 --> 00:00:26,966

The 400/500 series is not much different from the 100/200/300 series.

6

00:00:27,466 --> 00:00:33,200

In terms of power supply, there is only one more VCCIO2 and VCCSTG

7

00:00:34,600 --> 00:00:39,866

Moreover, VCCSTG, VCCST and VCCPLL of most mainboards are connected together,

8

00:00:40,333 --> 00:00:43,066

which is a power supply

9

00:00:44,933 --> 00:00:48,600

VCCIO2 is a power supply added by Intel on the 11th generation U

10

00:00:49,033 --> 00:00:53,333

in order to distinguish the 10th generation U from the 11th generation U.

11

00:00:55,600 --> 00:00:59,533

The VCCIO2 power supply is added to the 500 series mainboards

12

00:00:59,866 --> 00:01:03,966

And some 400 series mainboards cannot use the 11th generation CPU,

13

00:01:05,000 --> 00:01:08,533

because they do not increase the power supply of VCCIO2.

14

00:01:09,700 --> 00:01:15,033

In other respects, there is no difference between the 400/500 series and the 100/200/300 series

15

00:01:16,900 --> 00:01:19,466

The biggest difference is the 89 series

16

00:01:20,100 --> 00:01:26,266

Compared with the 100/200/300 series, the 89 series has a big difference in power supply and PG signal

17

00:01:26,666 --> 00:01:30,800

The first is the power supply, the memory main power supply VDDQ

18

00:01:31,300 --> 00:01:35,166

The main power supply of the 89 series memory is 1.5V

19

00:01:35,366 --> 00:01:42,466

Because the 89 series uses DDR3 memory, its memory main power supply voltage is also different

20

00:01:42,700 --> 00:01:46,166

Next is VTT 0.75V

21

00:01:46,866 --> 00:01:53,166

The DDR3 memory used in the 89 series does not have VPP power supply or bridge core power supply

22

00:01:53,700 --> 00:01:57,066

Bridge digital-to-analog conversion power supply, ME power supply,

23

00:01:57,300 --> 00:01:59,600

these are not in the 100/200/300 series

24

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

And the CPU core power supply voltage is relatively high, generally around 1.8V

25

00:02:06,866 --> 00:02:08,500

Look at the PG part

26

00:02:09,066 --> 00:02:12,100

It has a little more PG part than the 100 series

27

00:02:12,200 --> 00:02:15,366

Such as APWROK and DRAMPWROK

28

00:02:15,533 --> 00:02:18,866

These are not available in the 100/200/300 series

29

00:02:19,466 --> 00:02:23,400

So the 89 series also needs us to remember

30

00:02:23,766 --> 00:02:29,800

The older 67 series are not listed because there are relatively few repairs at present.

31

00:02:30,400 --> 00:02:35,333

Well, the above are the conditions required after each series of mainboards are triggered
