Basically I think at a certain point you're not doing yourself any favors by obsessing over which settings to choose, or whatever, because from experience I know that everything will just make a whole lot more sense once it's up and running in front of you. And the BIOS/UEFI these days provide you at a sentence or two of help for almost every single option.
Probably a sane procedure (in high level terms) might be
1. speed step off, push up to 1.25v or 1.3 or 1.2 depending on how much heat you can or want to deal with
2. find stable point after a few boot & tweak cycles
3. tweak ram clocks, timings, voltages. Bunch more boot & tweak cycles here
4. Don't forget to also work on increasing uncore and cache clocks and voltage, as real perf gains are to be had here
5. maybe flip speedstep back on and use offset voltage. This way the machine will be more power efficient when idle. How important this is to you is very subjective.
I get a kick out of conserving resources. Even though my house is now fitted with solar panels and electricity is by leaps and bounds cheaper than before there is still an inherent satisfaction to be had when your device is capable of sipping power when it doesn't need more. In my case I will have a PSU and a GPU which both have 0 RPM fan curve modes, and besides the Sabertooth will let me plug in and control all the rest of the case's fans, so when I can limit power consumed I can experience that golden silence.
