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

GPU-Z the best option...

GPU-Z will do for dumping, but it's better to use nvflash because this is what you'll use to flash back the modified BIOS. So you might as well get familiar with it.


I prefer to use it in DOS with a bootable USB stick (easy to make with Rufus), but you can also do it in Windows.


Run nvflash --save backup.rom from the command prompt to backup the card bios.

VBios: http://www.techpowerup.com/vgabios/127126/asus-hd7750-1024-120705.html

Or look on site for right card.


Place VBios file in UEFI-GOP-Maker folder as original.rom

Double click UEFI_ROM.command, resulting file is uefi.rom


Make a bootable DOS USB key with this info

Atiflash info: http://www.techpowerup.com/forums/threads/how-to-use-atiflash.57750/


Place uefi.rom on same key, boot from it

type: atiflash -p 0 uefi.rom


and if all goes ok, your good to go.


Just remember there is a risk when flashing/modding and I will NOT be held accountable for same.


I just tested

it's amazingly simple

Thank you

It is interesting to see universal UEFI BIOS. STLVNUB, can you confirm it working?


This is my working UEFI BIOS for Gigabyte HD6670, joined from native F1 and new F12 which are officially non compatible.

See also DeviceID in the GOP part. I afraid it should be corrected to your card and the checksum corrected too.

Confirmed,Gigabyte HD6670 is not compatible with Turks

If you need help

Please,plug cable to iGFX,set up UEFI to use iGFX,run windows,run atiflash,type

G:\atiflash>AtiFlash -p -f 0 Turks.rom
Old SSID: 2557
New SSID: 2012
Old DeviceID: 6758
New DeviceID: 6758
Old Product Name: GV-R667D3-2GI/F1

New Product Name: TURKS XT 1G/128B DDR3 DLDVI-D/VGA/HDMI 800E/800M

Old BIOS Version:
New BIOS Version:
Flash type: M25P10/c
20000/20000h bytes programmed
20000/20000h bytes verified

Restart System To Complete VBIOS Update.

Confirmed,Asus EAH6450 bricked Sapphire HD5670

Confirmed,this UEFI VBIOS works,but it does not boot when I am using Secure Boot restore UEFI BIOS settings to default,it does not acclerate in UEFI BIOS but acclerate in OS.

Hi, guys! I created my ROM with V4 for my ASUS EAH6850.

Everything works well so far, except that there are some graphic issues in my MB's bios setup interface:




Does anyone have the same problem here?


Btw, thanks to everyone who contributes to this great work!  :D  I've been looking forward to get a UEFI GOP for my 6850. And there it goes~ :whistle:

I have the same problem.and the turks crashed randomly...

Hi !

Would someone be kind enough to reupload the EAH6450 Video BIOS with UEFI GOP please ?

I have this card, the EAH6450 SILENT/DI/1GD3(LP) exactly, and I'd like to update it.

Thanks for your help.
