Hello smile.gif
I'm not an expert by any means still busy getting my own overclock stable but k.

1. Limited voltage at 3.5
I think you mean 1.35 but anyways i don't think you can change that.

2. 4.6GHz at 1.35
Thats pretty good it all depends on your chip some will be able to get 4.6 at lower some need higher voltage. But in general thats pretty good i think, 4.5GHz on my chip thats about the same voltage.

3. If 1 worker fails on prime95 that means your OC isn't completly stable.

Interal PPL Overvoltage is usually used for high overclocks (I don't know exactly how it works or what it does but usually needed for 4.8 or high overclocks.

The others i don't know.

Other settings to look at:
LLC: Second last option
Cpu Current Capability: 130%
Duty Control: T.probe
Phase Control: extreme

And do you get any BSOD's? If so tell us the stop code you get. For instance you can get a 124, 101, 09C these codes can tell you whats wrong with the overclock.

you're in the wrong section, that'y why, go to the Intel section and CPU or general subforum.
your OC is okay, you need more voltage thats why at 4.7 its giving you an error
