GTX650Ti PCI ID + Nvflash PCI ID Mismatch Problems

[ahmetkucukonder]

I have a GTX650Ti card but when I insert the card into my computer I saw that the PCI ID has 11C0(GTX660) instead of 11C6(GTX650Ti), the VEN and Subsystem IDs are correct. Only problem with DEV ID. When I look at the BIOS Version, I see that it is the same as the original version, but when I try to write the original BIOS on it;
PCI Device ID: 11C0 Firmware image PCI Device ID: 11C6 NOTE: Exception caught. Nothing changed! ERROR: GPU mismatch
I get this error.

I tried the Mismatch Patched version, when I use NiBiTor I get the error "Can't Start Driver: 1275", the GPU is not visible.
Anyone can help me?

Gigabyte GTX650Ti

Update
I did this by finding a different nvflash version, but when I restart the computer, "just" the PCI ID becomes 11C0 again
