Device information: Rescuer 2022, 12700H, WIN11.

Requirements: Install WIN10 and correctly install the driver, and solve the problem of large and small core scheduling.

Installed Version: Windows 10 Professional 1909 (2019 Dec) 18363.535

This article is mainly divided into two parts : 1. System installation 2. Configuration scheduling

1. System installation

The outgoing system is WIN11. Before reinstalling the system, please confirm the following preparations:

1. Driver backup (if any) : I use the built-in XX computer manager to back up all the drivers installed in the factory system.

2. BIOS setting : On the boot interface, press F2 to enter the system BIOS.

2.1 Turn off Secure Boot : Find Secure Boot in BIOS and modify it to disable.

2.2 Modify the hard disk mode : Find the SATA Controller Mode in the BIOS and modify it to AHCI.

2.3. Turn off VMD (if any) : Find Intel VMD Controller in BIOS and modify it to disable.

F10 to save and exit.

3. Boot: Note that the current mainstream boot method is UEFI, so please confirm that the hard disk partition format is GPT.

The above preparations are ready, and you can start installing WIN10.

Insert the U disk to quickly boot into PE, and the PE disk boot mode is UEFI, which is consistent with the BIOS boot mode.

The installation method varies from person to person, DISM++, etc. or directly mirror setup.exe to install.

I directly use the mirrored setup.exe to open for installation, and attach the command to quickly clear the disk and convert the format:

Enter the setup installation interface, shift+F10, call out the command window, and execute in order.

diskpart

list disk

select disk 0

clean

convert gpt

exit

exit

Disk 0 is generally the first disk, that is, the system installation disk, and it can be selected on demand in special cases.

After the operation is completed, the disk data will be cleared, all partitions will be cleared, and the partition format will be converted to GPT.

The setup interface continues to execute and the system installation is complete.

Driver Installation

After the system is installed and configured, all that needs to be done is to install the driver.

1. Driver compatibility issue : Don’t worry, most drivers of WIN11 and WIN10 are currently known to be compatible, unless the version of WIN10 is very low, such as version 1809 and lower versions may cause some drivers to prompt that the version is too low and cannot be installed problem, so try not to install too old versions.

2. Driver installation method:

1. Use the built-in housekeeper to restore the last backup driver. (This housekeeper cannot be fully restored, it may be a system difference)

2. Unzip the driver file backed up last time, manually identify the driver, and install the driver.

3. Enter the official website, search for the corresponding model, download the driver and install it.

3. Driver installation sequence :

1. Network card driver: Network connection is the first priority, and the priority is to install the network card and access the network.

2. Display driver: If it is a core display plus an independent display, no matter which one is equipped with which one, the core display driver is installed first, and the independent display driver is installed after confirming that the core display is installed successfully.

3. Other drivers: There are basically no special requirements for the remaining drivers. Pay attention to the driver named Nahimic (if any), this driver does not affect the normal use of the computer, it is not recommended to toss, it is recommended to disable the driver manager directly.

Normally, the device manager will report yellow if there is no display, and the basic interface is plugged in to read or output normally, and the driver installation is complete.

Yes, the system will not limit, as long as all the drivers are installed. The principle of official software control can be understood as sending commands for execution, and after the hardware is connected, the driver acts as a medium to receive commands for execution.

After testing, RGB, shortcut keys, mode switching, etc. are all normal.

As for the control management software, Lenovo Legion Toolkits is recommended.

2. Configure the scheduling size core

statement

If you ignore the performance of the small core, you can enter the bios, turn off the E core, that is, turn off the small core, and the big core will be used in daily life, but the three buffers will also be reduced.

If the performance of small cores is not ignored, the following operations can be ignored by users who do not care about the scheduling of large and small cores.

Since the 12th generation Core introduced the concept of P+E core size, but the scheduling on WIN10 is not as good as WIN11 (not much better).

In order to make the best use of everything, the big and small cores are scheduled, using bilibili - a scheduler developed by maxppa.

The corresponding scheduler version used is Apple Scheduler 1.4.

Note: The scheduler will overwrite the current registry. If you have any concerns, please back up the registry for easy rollback.

start configuration

1. Open NSudo, batch file, and a processing box will pop up.

2. Open the kernal file in the same directory.

3. Click Run.

4. Open the Core-sized core scheduler in the directory, and configure the scheduler activation.

5. Generally, the default is enough, activate the power plan, and the screen brightness is instantly full, which means successful activation.

After restarting the computer, perform a scheduling test to check whether the scheduling is normal.

Test software: CINEBENCH R20, R23.

Before scheduling, run the R20 test, no matter how many rounds, the small core runs full, the big core does not move, and the running score is about 1700 (very low)

Excluding differences in bios, cpu constitution, ambient temperature, and default scheduling configuration, the normal running score of win11 is roughly as shown in the figure below:

Source: bilibili - Zhongzheng Evaluation.

After the default configuration activates the power plan scheduling, the running score of R20 under WIN10 is as follows: between 6400 and 6600.

R23 running points are as follows:

It can be seen that the scheduling of large and small cores is already normal. From the point of view of the score, it is close to the running score under win11, and the difference is about 10%. Excluding the above factors and some scheduling configuration factors, the scheduling under win10 is already normal.

Install WIN10 on Intel 12th generation processors, and solve the scheduling of large and small cores.
