Well i was wondering if they actually make a difference? For example intel speedstep, now how can changing the processor speed affect power usage when ive set the voltage to the cpu to only 1.08v. Does it actually work? Or should i disable all these cpu options, because i believe my pc would perform better and shouldnt use any more power with them off, am i right?.
Also, can you change the values for gpu's for idle? Mine idles at 160 core and 250memory but i bet i could bring it down
