Hi. I really need some help. I am trying to this method on a desktop mobo to be able to get more performance from an i5 4590. The issue is that when I extract files 1 and 3 with Uefi Editor and proceed to use the HexEditor to modify them, it's completely different from what your screenshot shows and I am scared to screw things up and brick my motherboard and make my PC unusable ever again.
Here is the BIOS file that needs the mod to allow CPU overclocking: http://www.mediafire.com/file/z6ppd2lf4n8opq9/7817v67.rar/file
I hope someone can give me a hand.
Thanks!
