Well not stable at 2800 mhz and doesn't seem as nice as Entuscan's but is doing pretty good so far.
I have been testing it at full 3D runs on a KX7 and this how it has gone so far cooled by a Prometeia:

Stock voltage it did 3D at 2360 Mhz
1.75V got 2500 Mhz in 3D
1.85V got 2585 Mhz in 3D
1.97V did 2675 Mhz in 3D
2.10V did 2720 Mhz in 3D

Still working on her and I'll put her on my KD7 tommorrow and do some real 3D runs and see how far up the first page of the Orb we can climb

Here's a little 2800 AMD madness
