As far as the behavior of the Vcore is concerned, I really like the Asus LLC implementation actually and the setting of Ultra High is just about perfect for running 2500K/2600K processors at 4.7-4.9 GHz. The Asus engineers really outdid the competition on this generation of boards and the amount of power delivery control options you have.
Although I posted after you, I didn't see your response because I immediately went afk... lol

Been playing with it a bit more. As others have hinted, there's a steep vcore hill. For mine it's 4.8 - 4.9 GHz. I finally got 4.9 GHz > 5 min. stable. I didn't want to test longer because my temps were getting high. (Normally, I don't have this problem, but right now, I don't have my rig setup properly to get sub-zero air from outside. )

The difference between 4.8 GHz and 4.9 GHz was 0.040v. Between 4.7 and 4.8 was only 0.015v.
I tried 5.0 GHz using the marginally stable 4.9 GHz settings - blue screened about a second into my multi-threaded pi benchmark.
I'll try again later - gotta catch up on homework.

I booted up with a 4.7 GHz prime-stable setting. Then upped it via AI Suite.

These are all AI Suite settings:
4.9 GHz
Vcore = 1.230v
DDR = 1.5v

Load-Line Calibration = Ultra High
Current Capability = 120%
Frequency = 350KHz
Phase Control = Extreme
Duty Control = Extreme

Load vcore came out to be about 1.42 - 1.44. Temps were 80 - 85C. Ambient was about 72F. I'll try again later with sub-zero ambients.
