Looks like you have a chip which is better suited for 4.7GHz or below. That's just the way it is. As I've said, these chips differ very much in how much Vcore they will need for a certain speed.
As I've also said, they are so fast that some people don't even bother to overclock them. Really, be happy with what you've got. A couple of hundred extra MHz will not give you any noticable difference
When playing Fallout 3, with lot's of mods, I had CPU-Z and Core Temp open on my seconadry LCD, and the Cores was barely loaded at all. In fact, CPU clocked down to 1600MHz all the time. These are so fast, that I've even heard people forcing them down to a constant 1600MHz and they didn't even notice any lower performance in games.
You weren't kidding about the 4.7Ghz, my results are below

Cheers for the advice bud - I dropped LLC to Ultra and my VCCIO is currently set at 1.500v.
Unfortunately my chip couldn't manage 4.8GHz at a voltage I considered acceptable... however, I have achieved a stable overclock at 4.7GHz which I'm very happy with!
It has currently survived 45 minutes of turricans extreme settings in the Prime95 Blend test at 1.432v which I am content with for 24/7 use.
Max temps are below, with my CPU fan speed locked at 75%;
Core 1 - 67c
Core 2 - 70c
Core 3 - 69c
Core 4 - 69c
Prime95 is still going and temps are sat at 64-66c across the board. I'd like to extend a big thanks to everyone who offered their advice and helped me get this far.
