yup its all up to the user but the voltage spike over idle in llc, happens in a fraction of a second and occurs because there is almost no voffset that the vrm is accounting for. Yea someone over at overclock.net told me the RE3 has the same 3 levels just with percent instead of levels. Funny thing is that even at level2 gigabyte boards vdrop is still there and LLC wont take the votlage above what you set, just up almost next to it, but i guess thats better than voltage increasing more than you set. Im pretty sure both will results in a voltage spike going from idle to load. Ther eis also the difference that the RE3 and R3F both have 8 pahse analog and a digital hybrid VRM which can acount for many differences, this is why i made this thread for gigabyte. You need an oscilloscope to detect it.
