hi everybody...

 

Do you think it's possible to add UEFI Gop in a gainward GTX 660Ti 2048 Mb please ? (not phantom edition)

I hope it's not a stupid question...

 

This is my BIOS, extracted with NVFlash :

(gainward never made such bios for this card, instead of asus with the GTX660 TI-DC2-2GD5 whose UEFI bios can be found here :

Thanks a lot...

Here's one I made with GOPupd 1.9.1. See if it works OK.

 

Thank's Riley !!

 

Just a small question please, before flashing : is it normal that the mod bios is smaller than the original ?

Yessss Riley ! It's working like a charm  :thumbsup_anim:  :thumbsup_anim:

Thank's, thank's a lot, you're a great man...

 

I don't know this tool (GOPUpd), so now i'm trying to understand it...

 

Now i can boot in Ultra fast mode with my Gainward GTX 660Ti and Asrock Z77 Extreme6, it's very pleasant  :yes:

 

Thanks, may the force be with you Riley, and for all members of this forum too !

Hello, I made the bios modification on a video card from Gigabyte "GV-R785OC-1GD" with the member of the tutorial "Tedascuen".

It's working perfect in UEFI, I have not tested the "fast boot".
But when I'm browsing the motherboard BIOS options, it has a certain slowness in transitions, mouse arrow "breaking" the movements. Type "drop frames" in the BIOS.
Do you have any way to increase that speed and improve the flow?
Tutorial that followed was this:
 
My BIOS:
 
Original BIOS:  Pitcairn.rom.zip
 
UEFI BIOS modified: 7850UEFI.rom.zip
 
Thank you friends

I haven't had any issues like that when navigating the BIOS menus. Try this one and see if there's any improvement.

 

You should always dump the rom from your card when modding. Never rely on a bios downloaded from elsewhere because it may not be as compatible as it claims. Especially if you start seeing weird behaviour after modding.

Friend with that his solution was a little better.

Thanks and thank you.

Ok guys I have strange one here.  When I look at the database my EVGA bios should be a 178k bios but when I use gpu-z its only 92K.

 

 

Here is the link to my Card.

Its the 2 gig card.  I know I need at least 128K to update to GOP.

 

 

Basically the same cards as the two gig card in the photo

It doesn't matter what size your card bios is. Once you add the GOP segment it should work.

 

There's no need for the resulting BIOS to be at least 128k, although if it's smaller you may have to force flash it in some cases (like ATI).

 

My original GT210 bios was 62.5k and 122k after adding the UEFI support and it flashed and worked without a hitch.

No way really I have a GT210 Im dying to try but I'm afraid!.  I really need another uefi graphics card laying around for trouble shooting and bootcamp!  Going to try the EVGA first.  Fingers crossed.

 

 

 

snakeman

 

 

 

Update:  It worked in windows 7 "gpu-z"  has a check mark on the UEFI square wow.

 

I used this tool to create my GOP.

 

"Awesome! GOPupd is another tool for adding GOP support to video cards. I mentioned it earlier in the thread."

 

 

Thanks Andy Vandijck Thanks Riley and everyone that risked their cards.

 

 

New Update:   GT218 did not work for me.

 

Error: rom image to large for eeprom  :(

Thanks, I have a few more cards lying around to try;  GF119 hmmmmm.  I checked online for some cards, thanks again.

 

Now to update my motherboard bios to see if fast boot actually works.

 

ozmosis or clover???

 

 

Report back later.

 

 

 

Update:  My GF119 works so far.  Its a Zotac 610 1 gig card.  Wow, very happy with that one, very surprised.

 

Here is the exact card.

Post a dump of the card bios and I'll GOP it for you. I'd rather work with an actual dump from your card than assume it's the same BIOS revision I have.

How i dump VBIOS ??

1. Using Clover 

2.Using Darwin Dumper 

3. Using GPU-Z in Windows 

 

please let me know (pretty noob here )

 

thanks you
