According to https://www.youtube.com/watch?v=x9DJ18y8LcI&t=2s it could be 1.9Gh/s Ethash at 150w which is incredible

If the video isn't an outright fake, I'm going to hazard a guess on what is going on here. It is almost certainly doing a solo running benchmark run with 0 generation DAG, which fits into the card's UltraRAM.
You'll never achieve that kind of a number any other way. Even if you put in QDR2 SRAM modules in those DIMM slots it won't help you because IIRC you can only get 288MB worth of those in - far less than the 3GB+ you need for current DAG size for ethash based coins.

It show 0.9999 GB DAG generated in the console, is that the size you are referring to?

I missed that, but now having taken a closer look:
1) DAG used is < 1 GB
ETH has a DAG of 3GB at this time.
ETC has a DAG bigger than ETH.

2) It apears to be using ethminer in OpenCL mode.

There seem to be a lot of red flags in those few seconds of video.
