The Razer Blade 2018 (and probably some other versions) don't have the "Overclocking and Performance" menu under the "Advanced" header, and there is no easy way to turn it on. So lets just make a new link to it in the main menu.1. Open UEFITool2. Select File>Open Image File3. Select Modified_BIOS.rom/Final_BIOS.rom4. We need to find the section titled "AMITSE"Mine is under these sections:and here is the section:5. RIght click the PE32 image under AMITSE6 Select "Export As Is"7. Save as "AMITSE"8 . Open AMITSE.sct in your favorite hex editor9. Refer back to your "MenuBinary IFR.txt" file. We are looking for the highlighted section. Yours is likely the same as mine. Copy this portion of your text10. in Your hex editor, search for this hex code in AMITSE.sct11. You should find several references, the first one is unrelated, we are looking for the block with several in a row. As such:This block of six references creates our main screen menu options in the BIOS. The next 4 numbers reference back to our MenuBinary IFR.txt to determine what to displayed. In my case, the first is 11 27, and if we search MenuBinary IFR.txt for "2711" we find "0x308C9 Form: Main, Form ID: 0x2711 {01 86 11 27 09 00}"If we are lucky, such as I am, we have some empty space immediately following our last entry12. In MenuBinaryIFR.txt find the form id for overclocking performance menu. In my case, it is 0x279413. In your hex editor, in the empty space following the last entry, type the meny entry exactly as the previous one, but this time the next 4 numbers will point to overclocking form id (in reverse, such that my form id - 2794 becomes 94 27)14. Save this as AMITSE_MOD.sct15. In UEFITool, right click the AMITSE PE32 and select "Replace as is"16. Replace with AMITSE_MOD.sct17. Save you modified rom.IF YOU DO NOT HAVE EMPTY SPACE AFTER THE LAST ENTRYDecide which menu item you like the least (likely security) and change that reference to your overclocking.
