[SOLVED] GTX 770 being recognized as GTX 760, very confusing

[1337Skrjabin]

Hello everyone! I've stumbled upon a weird problem and i wanted to ask you for help. Recently, after a long time since using my old gigabyte gtx 770 4gb, i put it back into my pc. It is working fine but for some odd reason, gpu-z recognizes it as gtx 760. Trying to solve this, i installed the latest avaliable bios for my graphics card via nvflash, installed the most recent gtx 770 nvidia driver but gpu-z still thinks it's gtx 760! What would the secret be here? Some other specs such as vram are displayed correctly but the gpu name is wrong.
I know that there are two very similar gigabyte 760 4gb and 770 4gb graphics cards but i'm sure that mine is 770. Besides, it has GV-N7700c-4GD written on it's pcb.

you see, i took this stone age artifact out of my cupboard because i want to sell it. And any potential buyer would freak out or think that i'm trying to fool him if i say that it's 770 but gpu-z identifies it as gtx 760.

GTX 760 and GTX 770 are made from same GK104 chip.
Only difference is

GTX 760 has 1152 shaders​

GTX 770 has 1536 shaders.​

​

Device ID is wrong, should be 10DE 1184 instead (not 10DE 1187).
You may have flashed wrong vbios into it.

Had a very similar problem yesterday with someone. Had a GTX 550Ti reporting as a fake GPU even, but the GPU was actually the correct GF116-400 (His was actually GF116-400A1). Device ID matched correctly but still reported as a fake unit. I'm beginning to suspect that GPU-Z is making mistakes with minor GPU revisions on older cards.
