I'm not familiar with MSI Z97 bios, but can view the manual and come up with some suggestions 
.
I do go manual settings for several settings as "Auto" may not be optimal.
For example on my mobo if you leave cache voltage "Auto", as you raise cache ratio higher than stock it automatically raises voltage. My stock cache voltage with stock ratio on "auto" is 1.10V but it will rise to 1.20Veek with higher cache ratio, this particular chip did not need extra voltage on cache. Some chips may react not so great with voltage increase, effecting the OC, so it is best to set bios as much as you require manually.
I tested manual vCore and found adaptive offset voltage worked the same and preferred that, so I would suggest you test what works best for you . These are the CPU/RAM related settings I change on my Asus Maximus VII Ranger from defaults:-
As each silicon differs on properties plus what cooling we may have you can use mine as guide loosely speaking but not as exact settings you may require.
My current CPU I set profiles from 4.4GHz to 4.9GHz (0.1GHz increments), you should be able to get a "feel" for how the CPU is reacting to OC'ing from first few profiles. I use x264 first, as it only stress CPU and is a cool stress test, 4.9GHz 48 loops ~8hr run screenie. Note the dates and times on taskbar
, pretty much straight after I ran 4hrs RealBench Stress mode, this will load CPU/GPU so the whole system gets a workout, screenie. Then I did do some gaming and just before turning in set rig to fold, f@h CPU/GPU full power 17hrs screenie.
Those screenies were from when I had a Vapor-X 290X dumping air in case, now with the Fury X AIO exhausting it's heat out of case my temps are better by ~5C in RB/f@h.
