Used these guides to get Son No. 3's box set up (2600k) ..... have saved BIOS profiles for stock, 4.0, 4.2, 4.4, 4.6 and 4.8 Ghz so far. I spent about 3.5 hours setting up each profile.... 5 minutes in BIOS and then a 30 minute run. I have him run torture tests at night after he's done playing....all passed so I'm sure further tweaking is possible.
These profiles are all set up so that the system is not overclocked 24/7..... it responds to load and only ramps up when needed so as to to extend system life. Voltages go below 1.0 when processor is not being worked hard and temps using typical everyday programs are in low 30s. I don't see the logic in being locked at 4.x GHz or firing 1.4 volts thru the thing 24/7 when ya reading THG Forums.

It's my 16 year old son's box so all settings are very conservative. Hope this helps.
4.6 Ghz - Everyday Profile
Per core multiplier = 46
Load Line Calibration = High
VRM Frequency Mode = manual
VRM Fixed Freq. Mode = 350
Phase Control = Extreme
Duty Control = Extreme
CPU Voltage Control = Offset
Offset Mode Sign = +
Offset Mode Voltage = 0.050
CPU Spread Spectrum = Disabled
Intel Speed Step = Enabled
CPU ratio = Auto
Hyperthreading = Enabled
CPU C1 Report = Enabled
CPU C3 Report = Enabled
CPU C6 Report = Enabled
Intel Virtual tech = Disabled
Vcore ranges from 1.31 to 1.34
Core Temps are 59, 63, 64, 59 under full torture test (OCCT, Linpack, Prime 95) loading
4.8 Ghz - Gaming Profile
HT useless here so I turned it off

We had a 5.0 Ghz profile under the old MoBo
Upon boot, if ya wanna change profiles you simply enter BIOS and tell it which profile to load....1 click switch.
Cooler is Thermalright Silver Arrow which is generally about 1/4 warmer than the H100 but much quieter.
I just replaced the MoBo (P8P67 WS Revolution) under an RMA which suddenly stopped recognizing the SSD and GFX card..... haven't had time to try and push it any higher. Danged kid got too many games for Xmas and I cant get any time on the thing
BTW, I use OCCT to do my 30 minute testing (no need for additional temperature and voltage monitors), memtest86+ for memory and prime 95 for final stability test.
