If I need 1.34 load vcore for 4.4ghz stable, I have 2 options.
option 1) Use LLC, and I can set 1.34v core in bios. (Overshoots will be to ~1.39).
Or option 2) LLC off, and I set vcore to 1.39 in bios, and load vcore drops to 1.34. (Overshoots will still be to 1.39 as vrm circuitry is same). And higher the load, the lower it will drop, hence the unnecessary guessing game.
LLC off is annoying to me, as it is pointless, since its intended use is already circumvented by overclocking. Others it doesnt seem to annoy.
This really depends on the board.
On Asus boards, LLC has 0%, 50% of rull:
0% means it lets the cpu to vdrop as it wants.
50% means that it will let the CPU to vdrop, but it will also up it back to as set in bios when needed.
Full means that it will keep the volt as set at bios, and ramp it up when its needed.
Gigabyte acts a bit different:
Standard - llc disabled.
level 1 - will set the volts to what is at bios, and let the cpu to vdrop when it feels like its ok.
level 2 - similar to full at asus, except at load it will just keep the volts up.
