*********** UPDATE JUNE 2/2018: The 64KH/s hash rate is mostly likely fake. GPU_Hoarder has achieved 22KH/s which is the true hash rate for CN7*************
@GPUHoarder, can you share more info on 22KH/s CN7?
yes we want to know about 22KH/s on CN7 or its also fake or we can go beyond this to achieve 64kh.?

22KH/s is at over 300W iirc. So if you push that card to the max, that's what you might achieve... at the risk of melting it.

In the other thread they advertise 14KH/s@150W I think... which would make sense.
