A few observations before we start.

With this procedure you can change many options relevant to your Hackintosh like Above 4G, CFG Lock, CSM Support, DVMT Pre-allocated, Serial Port, TPM State, XHCI Hand-off, etc.

Some manufacturers make this option available directly in the setup, just disable/enable.

This procedure is not advanced, but has minimal risk. You are at your own risk.

If you update the bios or use Load Optimized Default / Clear Cmos, you will need to redo the procedure.

 

1- Download the Bios/UEFI file from the manufacturer's website. Some manufacturers like Lenovo provide the Bios packaged, in this case you need to extract it before starting this process.

 

2- Open the downloaded file with UEFITool

3- Look for DVMT in the Text tab

 

4- Select what the search returned. In this case is Setup/PE32 image.

 

5- Extract as is... then save

 

6- Download ifrextract, open terminal and drag this tool, drag this saved file and output set to PE32.txt. Check image bellow. (on Windows use this version HERE)

 

7- The file was generated

 

8- Open the .txt file and search for DVMT Total Gfx Mem and we have DVMT Total Gfx Mem, VarStoreInfo (VarOffset/VarName): 0xA5, VarStore: 0x16 in this case. What really matters to us is 0xA5, VarStore: 0x16.

You can check the values to change, which value is default, etc. Check image bellow.

 

9- Before we continue, let's confirm where to change the values. Search for VarStoreId: 0xXX. Need replace the value with whatever is returned from your Bios/UEFI file. In my case it was VarStore: 0x16. So I need to search VarStoreId: 0x16. The result is Name: SaSetup.

 

10- The result in this case is 0xA5 in SaSetup and le'ts change it to 0x3 = MAX.

 

11- Now let's get to the serious part. Download Ru.efi or this EFI folder EFI CFG RU.zip (You can update the file in the EFI folder. Just rename the RU.efi file to BOOTx64.efi and replace it in the BOOT folder)

 

12- Format a pendrive as HFS, mount the EFI partition and paste the EFI folder

 

13- Boot from the pendrive and you will see a screen like this. Press Enter.

 

14- Use Alt + C and select UEFI variable

 

15- Scroll down to SaSetup

 

16- Navigate to 0xA5 which was the value found in the first step of this tutorial

 

17- Change this value to 03 which was the value found in the first step of this tutorial then use Ctrl + W to save and Alt + Q to exit
