Question about eist...

Does it just lower multi? Or does it touch the voltage as well?

If it changes the voltage as well, you'd have to play with vcore percentages (do intels have this?) over 100% to use so that your say 115% is equal to the voltage you want, so when it ramps up, it goes to the right, stable voltage. Of course that doesn't matter if Intels don't change the vcore...
