I am having the same problem with same board Extreme4 Z77 but with 2500k and windows 10 x64. Locked multiplier at 37x, no integrated graphics, and no ram overclocking (stuck at 1333mhz).

Can someone link me to the files I need to do this?

I found the below steps on another post so I think I have an idea of the steps I need to perform.

1. Download the attached ME.rar file which is the ME firmware found inside your motherboard's latest 2103 BIOS
2. Download FTK9_0.11 (FTK for 8-series systems) from CodeRush's github
3. Extract the ME file from step 1, extract FTK9_0.11, go to Windows folder and copy the file bios.bin together with the .bat files
4. Shut Down the computer
5. At your motherboard, find the Realtek Audio chip
6. Use tweezers or a paper clip to short together pins 1 and 5
7. Power the PC on and wait for POST screen to show up
8. You can now stop shorting the two pins
9. Boot at Windows (you are now running the system with an unlocked descriptor)
10. At FTK Windows folder, open a command prompt as administrator and type merefl
11. After a successful ME restore, type poweroff to shutdown the system, restore the lock & reset the ME
12. Run MEInfo & MEManuf v9.0 tools from the ME thread to check that everything is working properly

I thought about creating my own thread but since it is the same board I thought I would just use this thread. Funny how the OP and me both posted the problem on the the same day one year apart.

Thanks in advance for any help.
