Im curious why you want to keep the voltage that low? What is your goal for the cpu, getting it to run at the lowest voltage possible at stock clock? Remember, every cpu is different. I just upgraded to a 4790k from a 4770k. My 4770k was a pain to get stable at anything over 4.2ghz. It took alotta tweaking! Some lucky people could set everything on auto, extra voltage at 1.2, cpu level up to 4.6 and make post no problem! Its all in the chip!
I'd say don't be worried about the voltage going up that high, especially if your using adaptive mode. (just don't use any synthetic benchmarking tools while on adaptive) Most importantly, you wanna make sure your temps are staying nominal. If your goal is longevity of your cpu, maintaining low temps is everything! If you have a decent cooling system and your temps are good, then a little extra voltage won't hurt it. And remember, in the long run, using manual mode is the least efficient, especially if you're not overclocking your cpu.
I only upgraded recently, but thus far in testing my 4790k peaks at about 1.264v under load and temps have stayed below 70c! Thats been with the cpu @ 4.8ghz and ram at 2400mhz! Last night i had to up the additional turbo mode voltage to 1.280 for more stability and my temps are still low. Im also using adaptive mode.
I found the guide on this forum for my hero vi to be very helpful in getting a stable overclock. It should be easier to get that stability on a hero vii mobo, especially if you're trying to run your cpu at stock clocks.
