Wrong Graphics Card Drivers

[Sergio_18]

Hi, I have a small problem. SO a while ago I purchased a "GTX 750ti" off of eBay for $85. After some tests I realized it was under performing A LOT, and other inconveniences. Still, The card was running 750 ti drivers and registering as one. After further investigation I removed the fancy heat-sink, finding a GTS 450 processor. I immediately contacted the seller and got a refund plus I got to keep the card.

So my question is: How do I re-flash the card to say that it is a GTS 450 so I can use the appropriate drivers to avoid anymore glitches and bugs? Thank you.

NiBiTor can do the job. Use GPU-z to pull the BIOS then use NiBiTor to edit the Device Name which changes the "pci device id." Then flash the modified BIOS to the card with nVFlash.

Fermi-Kepler-Maxwell are similar enough that the drivers are probably mostly the same, but the differences may cause some issues. Performance isn't likely to improve though.

I remember when someone on Forum asked if seller is selling non-original card and I said yea he does sell.... does your card looks like this?

Yes, it's somewhat similar looking.

Wow, that's a bit complicated but I will go ahead and do some research. Thanks.

Hi, Im having trouble flashing. I'm getting the same " Command failed to complete mailbox0 = 10000002
Command id:0002 Command: NV_UCODE_CMD_COMMAND_EID failed
Command Status:NV_UCODE_CMD_STS_NONE Error Code: 00000001
Error: NV_UCODE_ERR_CODE_CMD_TIMEOUT"
Any fix?

I haven't ever tried it but if you can't get DOS nVFlash to work (it needs real DOS, not a DOS window), there is also nVWinFlash for Windows.

Whenever I couldn't get DOS ATIflash to work, ATIwinFlash in a DOS window worked great.

I've been trying all day but I just cant get it, do you know of any DETAILED instructions I can follow. I really don't want to brick anything

First boot to dos with a floppy (the instructions up to Windows 7 are the same as for XP). I prefer to use a Win9x one because then I know for sure it won't write anything to my NTFS drives. If you don't have a floppy at all you can use rufus to make a bootable USB. Or I suppose you could use your favorite iso editor to put the files onto a bootable CD.

The boot disk should have both nVFlash and the BIOS to be flashed.
Set your motherboard's BIOS to boot from it.

The syntax to force flashing is:
nvflash -f bios.rom
Where bios.rom is the name of the BIOS to be flashed. It should really be as easy as that but sometimes you need to do "nvflash -r" first to disable write protection on the BIOS. When you are done you can go nvflash -w to replace the write protection if desired

I found 5.163 was too big to fit on a floppy so I use 5.136 instead. It may be safer to use USB just so you can use the latest nVFlash.

nVWinFlash should be the same except you open an administrator command prompt window instead of booting from a boot disk. Or supposedly you can simply drag and drop your new BIOS onto it and click "Y" when prompted, but as I said I've never tried it.

Restart your PC after the process has finished.
