Ok guys I decided to do a bit more digging into it and took the picture and examined it very closely. From my examination I see a few things that make me question the legitamacy of this OC itself even. I found a good example of AOD to compare with this one. Look for yourself:

This is the "supposed" 4GHz screen
http://www.amd.com/us-en/assets/content_type/Additional/44348A_amazing_control.jpg
This is a screen from AMDs site.
Look at the text of the frequency across the CPUs in the first one compared to the second one. The first one the first frequency text is normal. Then the following three are bigger. Same goes with the multiplier, voltage and temp. Also the following three cores stats are all a bit more to the left than the first one.
Now AMD being a big proffesional CPU company would never allow this to happen and would want consistency in the looks of the program itself. I will take into account that they are probably different versions i.e. the one on AMDs site though is probably older than the one in the screen.
But I can most likely with out a doubt assert that this screen all together is fake given the larger text than some and the overall sketchiness of it.
I would also like to point out this: In the above picture somehow the voltages in CPU-Z and AOD differ. Some would say its because CPU-Z cannot read Denebs voltages correctly but if that were true then why does this picture show the voltage near what they had to set it to to OC Deneb to 3.44GHz?:

Note that the CPU-Z in this screen and the above screen are the same version, version 1.46. The last screen shows it as Revision: RB-C0 yet the other one has no Revision number yet is a stepping ahead of the last screenshot I posted. Both are ES (Engineering Samples) so I would expect both to have Revision numbers.
Lets also consider that post where the 4GHz Deneb came from was posted on 7/11/2008 yet the last screenshot I posted was from a article done on 8/02/2008. How can the earlier one have a later stepping number than the most recent chip info?
So to sum it up, the text on that ss is not the right size for all of it, the voltage in CPU-Z is wrong but is read fine on other Deneb chips and I am now 100% sure that this is all fake.
If anyone wants to try to dispute it feel free but you will be very hard pressed to do so.
