Thanks for the tip. I have also noticed that I found two variables for overclock variables "Overclocking Lock" and "Overclocking Feature". Currently I have enabled "Overclocking Feature" and undervolting is working, what about the "Overclocking Lock"? What does it do specifically?
Thanks,

I had actually written all the necessary parameters up in the first post, which are still applicable and working.
For ease of reference:
Code:
UEFI IFR
TESTED & WORKING
=======
*Undervolt CPU
(0x653) -> 32 (-0.05V)
(0x655) -> 01
*Undervolt GPU
(0x85A) -> 32 (-0.05V)
(0x85C) -> 01
*Overclock, CFG lock disable, WDT & XTU enable
(0x4DE) -> 00
(0x64D) -> 01
(0x64E) -> 01
*DVMT patch
