This is my experience with the CPU after delid. Before delid I couldnt get it near stabel for everyday usage above 4.8GHz. Temperatures reached the sky even going 4.9GHz (110C in Aida64 with room temps around 23c).
Asus Maximus V Extreme (bios 1707)
i7-3770K (MP 51x, 51x, 50x 50x, GHz)
vCore 1.52v
Corsair Dominator Pl. DDR3 ram 1.66v (CL10-12-12-31-2T, 2400MHz)
VCCSA 1.1625v
VCCIO 1.175v
CPU PLL 1.69375
EIST+C1E enabled, C3 and C6 disabled (Windows 8 power settings = balanced)
My criterias for calling it stabel are:
A few hours of BF3
A few runs of Windows 8 Experience Index
A few runs of 3dmark11
A few runs of 3dmark06
A few runs of SuperPi 1.5mod 32M
Just surfing around in windows doing normal stuff a few days
All of these scenarios without a single hick-up (strange behavior or crashes) made in a room temperature of 23-26c.
