GTX 760 with 770 or 680 GPU?

[thisarasu]

Can Anyone explain this?
Recently I bought a used GTX 760 from a korean vendor called Forsa. GPU-Z and NVIDIA Controll Panel shows the GPU with all 8 SMX clusters enabled. (Contains all 1536 CUDA cores of a GK104 GPU).
As I heard, GTX 760s are dristibuted with 2 SMXs disabled with a total CUDA core count of 1152 and 6 SMX. But this guy is with all SMXs enabled.
So in that case, How can I make sure what is the real GPU inside and whether it is possible to convert it to a GTX 770 with a bios flash?
Thanks in advance!

Seems already flashed, please post all possible pictures of the card, to see and try to look for comparations and specs online, also help yourself a bit, fill this!

The problem is, you can't really determine authenticity by looking at BIOS anymore... Just run some sort of 3D Benchmark, like Unigine Heaven or 3DMark Firestrike and compare the result to any GTX760 on the internet.
Otherwise you can void your warranty (if there is any) and simply look at GPU and VRAM. I've seen some weird specimens of GTX960 CE (stands for China Edition), which was basically a GT740 or GTX650 with a fake BIOS. It looked like a real deal, showed the right numbers in GPU-z, even played some games (much slower), but when you take off the heatsink, you'll see GK208 or GK106/107 instead of proper Maxwell chip.
