Sure if you are setting the same voltage in BIOS that makes sense as the 'real' voltage with no droop will be higher hence higher clocks. I think Spoolin was saying that if you compensate for that droop in BIOS but setting the voltage higher and have 50% LLC and Vtt LLC off is that the result is less electrical noise on each load line and the result of this cleaner power plane is often slightly higher clocks at the same real voltage.
