And I really think that he does know how to overclock a quad and he played with more settings, not just with the Vcore.
The Anandtech reviewer used a 10% (which is 100% + 10% = 1.1) increase on Vcore -> 1.2 x 1.1 = 1.32V. There's still a LOT of room to go with that chip, where did your math fail?
Your eyes are failing you, unfortunally. Read the overclocking page again and be very very careful, when they are saying this: "
The Core 2 Quad Q8400 saw a 15% increase in clock speed without touching the core voltage. Bumping the core voltage up to 1.45V bought us another 11% taking the chip up to 3.36GHz
Now you see it? Should I make the text bigger?

They upped it over 10% and there really isn't any more room to go from there.

In the review I linked to, both the Q8200 and Q8300 were able to make it to 460FSB, if the Q8400 can, that's already 3.68GHz.
In the review you've linked, they are saying this:
"
All that was required was:
set Vcore to 1.45V
set Vfsb to 1.45V
set FSB strap to 400MHz FSB
run the DDR3 memory at 1380-8-8-8-24
I could run most benchmarks without many problems at 475MHz, and could post at 500MHz, but I hit the FSB wall (reliably) at 460MHz.
Given that I've previously run this motherboard stably at 490MHz, the 460MHz limit must have come from this particular processor."
As you can see, they are again, using 1.45 V to achieve that overclock. 1.36 V is the maximum allowed for this chip, so I don't see too many people hitting 3.68 ghz by using 1.45 V ,being unsafe and probably on the verge of overheating the cpu. Once again, 3.6 ghz is not guaranteed for this chip, especially when not every motherboard is able to hit 460 FSB with a quad core.
You can't prove your point again, but there is nothing new about that.
