Microcode optimization i7 4700mq unlock

Viewers,

I was directed here from another forum regarding the unlocking of the cpu http://forum.notebookreview.com/threads/…ug-hack.790177/
I am attempting to change the microcode and when attempting to use the ubu there is an error message
CSM not found or cannot open extract file. What is the method that should be used to modify the microcode allowing access to the unused cpu. The computer is a Precision m4800 the processor is a i7 4700mq.
