Hello,  Does anyone know about video card bios programming or updating or changing or am I in the wrong place. I'm new to this
Found this site while grabbing at straws. Before anyone tries embarrassing me or anything along those lines. Let me apologize in advance. I don't want to disrespect anyone,but just cause I said I was new to this, doesn't mean I am new to computers. I started doing board level repairs on the 8088's For those who don't know what they were, they were THE FIRST personal computers running at 3.77 MHz. Then came the 286's 386's 486's etc. In other words, I'm 70 years old.
Anyway, I have an EVGA Ge Force GTX 660 ti video card. I didn't know when I bought it but it has no support for UEFI My motherboard is an MSI MAG B560 Torpedo with a Core i-5 11600 and 32Gig S.Skill RIPJAWS. Without UEFI I can't run Windows 11.   I can read the VBIOS with GPU-Z and save it as a rom file. I get no help from EVGA or NVIDIA or MSI Does anyone know what I am talking about, but more important, can anyone offer any help. Can that rom file be written to or changed or updated to give me UEFI support for the video. I can't really afford a new video card.

Unfortunately I don't think a lot of the skills you picked up there are necessarily applicable to your current problem.

Are you quite sure about that? Because it seems to me that I've been seeing a lot of workarounds for that lately – and even if they're inconvenient, they are surely easier than trying to reprogram your video card.

I'm afraid there really isn't very much discussion of such things here, and you would probably be better off in a forum with a stronger focus on video cards. But if there was an easy solution to this problem, I'm sure someone would have found it by now.
This signature is an illusion and is a trap devised by Satan. Go ahead dauntlessly! Make rapid progres!

Ignoring any debate about restrictions and whether they apply here (I actually don't know and have not particularly tangled with anything in the UEFI/TPM world thus far, which has been glorious).


Video card hacking tends to come in three flavours, most of which died off years ago.

1) Overclocking. Granted this tended to be more hardware side of things to allow better clocks, more stability (most reference designs barely use more than they need to to work at stock clocks, stick a few choice capacitors and inductors around the place, maybe some shielding and you can do higher clocks than others). That said some BIOS flashing was involved.

2) Unlocking. If things were binned lower or maybe had cores locked off to meet some standard then some would seek to open those up.

3) Driver shenanigans. Sometimes these were for speed, rarely they were to add overlooked cards (mostly amounting to edit inf file to include relevant hardware ID for things with chipsets still technically supported, or laptops), sometimes for stability, most were boring setups to dodge installation nonsense (can't say driver installers were adware installers but they certainly felt like they knew the same people), some were for allowing people to use the engineering CAD graphics cards (some higher end CAD requiring specialist workstation grade efforts despite underneath it all being retail cards with maybe the sorts of things workstations care about bolted on) either as gaming ones or vice versa.

More recent times have seen those locked out from calculations (see various crypto mining things) be unlocked again, though from what I saw this was just driver fun rather than anything real.


Barring the standoffish approach (this is not stack overflow) you appear to be able to write English pretty well, and if you have anything like the skills and free time required to play in the worlds you are looking to play in there are surely one off job boards looking for someone to do some more complicated things as one off projects to fund a fancy graphics card.
