Newegg video on ASUS P8P67 oc. Gets interesting from 9:20:
http://www.youtube.com/watch?v=3vBN-cBPs98
Observations around 5ghz mark:
Internal CPU PLL overvoltage = Enabled (for around 4,9ghz+ oc).
VCCSA, VCCIO, CPU PLL, PCH voltages didnt seem to affect oc.
LLC = Ultra High. Seems to be the optimal setting with manual vcore (to reduce voltage drop under load).
Short/Long Duration power limit didnt seem to affect oc.
EIST, C1E/C3/C6 didnt seem to affect oc.
(More info, look at the UEFI pictures)

Asus rep on OC'ing:

On VRM frequency:
Asus Ai Suite states higher VRM freq. should give better oc capability. My findings
"Increasing the VRM Frequency setting means the digital VRMs become more responsive to changes in CPU load, so a higher setting will benefit overclocking. This can be left to Auto for air-cooling and it'll run just fine. You can try anything up to the maximum of 500Hz, though, as Asus says this is still within the acceptable specification. The downside of using a higher frequency is greater EMI and more heat in the MOSFETs (as they're working faster), so your cooling must be better. Whether that greater EMI affects your system stability is up to you to find out" Link
Optimal OC settings suggestion (disregard CPU voltage and multiplier and try youself :-)
The not yet confirmed "Don'ts":
CPU PLL voltage over 1.9v.
Temperatures over 80c.
Increasing the VCCSA voltage.
DRAM voltage over 1.65v.

Prime95 seems to load CPU way more than LinX. Download link
