ASUS P8P67 Pro/Evo/Deluxe OC discussion thread
Post your results and bios settings.
Latest bios: 2303 BETA
- Improve system stability
Bios and drivers download links. Thx to SimpleTECH
Newegg video on ASUS P8P67 oc. Gets interesting from 9:20:
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
The not yet confirmed "Don'ts":
CPU PLL voltage over 1.9v.
Temperatures over 80c.
Increasing the VCCSA voltage.
DRAM voltage over 1.65v.
Stress testing Sandy Bridge:
Prime95 seems to load CPU way more than LinX. Download link
CPU-Z 1.56.3 beta: Download link
