Ivy can be tricky, I've seen this with high overclocks when benching. I have to get the voltage just right, bit too little = unstable, bit too much = unstable, have to find the right spot in the middle & then it works. Older chips weren't as picky, too much voltage may not be as good for the chip, but it worked.

I've always left it on auto, I haven't had any issues letting it enable or disable itself as needed whether at any clockspeed.

It's a vicious cycle. Air is fun until you try water, then you try phase & every ivy bridge chip can suddenly boot 5Ghz at 1.3V, but there are still limits to what it can do under load. Colder phase, then DICE, then ln2....
Liquid helium is like 10x the cost of ln2 & much harder to work with, but I want to try it...

and sign up (enthusiast league unless your computer room is full of phase change and LN2 gear)...I signed up with my OCN tag but obviously a different pw etc, and IMPORTANTLY, don't forget to choose overclock.net as your team as the points (boints) are both for yourself and the team you belong to.
...on the weekends, their web site can be VERY slow as a lot of folks are then on it and everything has to be updated
...under the 'benchmark' tag, choose where you want to compete (most competitions are for the video card class, i.e. 7970) and then also read the 'rules' as to what they want to see for verification when you submit a result for that benchmark
...here is the 7970 class...you'll see that it is by single card, SLI/CF, triples, and quads...see you at the other side
People do automatically start off in enthusiast & need photos with submissions to show the cooling. Just have to make sure not to accidentally select the wrong cooling when submitting, selecting a sub-zero form of cooling (easy to make a mistake in the drop down menus) automatically bumps the user to the extreme OC league.
In the benchmarks section at OCN there is an hwbot team section with some guides & tweaking threads, feel free to post for any help with the benchmarks or tweaks.
