Uncore clock and/or uncore voltage anyone?

Definitely looks like there's "an uncore voltage".

Does it really?

Phases on R600 are different than RV790's - from bottom up on R600:
- 6 vGPU phases
- 1 GDDR vDD phases
- 1 GDDR vDDQ phase

From bottom up on RV790:
- 3 vGPU phases
- 2 phases for ??? (clearly detached and controlled independently from vGPU)
- 1 GDDR vDD phase
- 1 GDDR vDDQ phase

It just means its power hungry

Actually no, that's ot what it automatically means.
It could, but it could also mean it's actually less power hungry.

But that was expected.

Like that RV790 was nothing but an overclocked RV770?

And largon used some l33t paint skills to depict what he was seeing, and 2 or 3 sites picked it up and claimed it to be proof.

Haha! That was just epic.
