I have a "fake" NVidia GTX 1050 Ti graphics card, and I'd like to try to get it running. Could someone help me by answering a couple of questions? First, here is the basic information I know about this graphics card, starting with a GPU-Z report:
GPU: GF116-200-KA-A1 (probably a GTS 450 Rev. 2?)
BIOS Chip: Pm25LQ020
Memory: K4G10325FE-HC04 (GDDR5 - 8 chips, 4 on front, 4 on back of PCB = 1GB?)
Connectors: HDMI, VGA, DVI
I have a CH341A programmer with a clip that fits the BIOS chip. I installed AsProgrammer 1.4.1, but it does not appear to include the specific BIOS chip I need to flash (Pm25LQ020). I tried a different option (I think it was Pm25LD020) and it seemed to read and write okay, but I'm not confident this will work. Is there some way I can get the specific BIOS chip (Pm25LQ020) as an option in AsProgrammer? Or maybe using one of the other chip options is okay? Or maybe I should be using another piece of software to flash this chip?
The other problem I have is identifying which BIOS to flash onto the chip. Looking in the TechPowerUp database, the card that fits this description best is the ASUS GTS 450 (ENGTS450/DI/1GD5), but I'm not certain about this. I filtered TechPowerUp's VGA Bios Collection down to 16 possible BIOS options that look like they would work with the ASUS card, and eventually settled on one that has the same core/boost speed and flashed it onto the chip (using, like I said, the wrong chip option in AsProgrammer). It seemed to work, as far as I could tell. But when I tried to use the card, it wasn't recognized as an Nvidia card, only as a Microsoft Basic Display Adapter, so I couldn't install any drivers:
It could take forever to try to find the correct BIOS to use. Any help would be greatly appreciated!
Thank you,
Corey
