Well it's business on EVGA's end. Ego on however that dude spells his names end.

The secret is the ambient temp. Providing low enough cool air, GTX680 can reach 1.4GHz and above with no problem.

Here is an air-cooled Zotac GTX680 Extreme edition (with factory improved VRMs) reaching 1.47, 1.48 and 1.5GHz.
Note its reference cooler is replaced by a Thermalright Ultra 120 Extreme. (It is a pity that end user did not bother to test the Zotac stock cooling which is a very decent design itself. I just wish he did.)
Note the setup was right in front of an typical home air conditioner.

It has way more to do with voltage then anything you posted there. With the 680 you can only force a constant 1.175. You cannot raise it higher. As you can see from the pictures the overclocker was able to raise the voltage to 1.212. All the other crazy 680 OCs have hardmodded stuff added to them in order to increase it.

I can't understand chinese but I absolutely gurantee you those clocks were reached with the add-on voltage board.

So it'll stay secret for now, until someone else leaks it.
I will say it's not something most people can do at home. There's some magic involved.
He's right guys its all magic. They just put a table sheet over the setup, said "abra kadabra", and voila some almost unbelievable numbers. If I had a 680 I could do it too thumb.gif

i'm sure evga / nvidia just gave him run-of-the-mill chips to work with

That's what I was figuring, I think they just used a really cold room (think a giant freezer type place). That was they could still use the reference air cooler and it's not something regular home users can do like Phaedrus said because we don't own big freezer type rooms.

And an add-on voltage board. I don't know why you guys are glossing over this huge part of the picture. Otherwise people would be hitting these numbers on water all the time.
