Is there a smaller UEFI GOP module to insert or a compressed version? To try to fit it in. How can I know what my BIOS chip size without the hassle of opening it?
I am fully aware. Not afraid of killing the GPU, I have CHA341 on hand and I have some skills. Just trying to spare me some time.
The Gainward GTX 570 (Not GS or GLH model) has the BIOS chip Pm25LD010 (Full name on the chip is Pm25LD010 CE1142 HNHT1HG). Sadnly couldn’t confirm which size is it (512Kbit / 1Mbit / 2Mbit, I would have enough space for the new BIOS only if it is the 2Mbit as I understand).
Edit (from previous post, just to make sure… sorry): Also as I understand from you the errors I got from the GOP-Updater are normal and not to be afraid of as the injection was done successfully.

Yeah but this doesn’t mean you wont get a broken card just like the attempt of this user with a EVGA GTX570…
Already told you that it is unlikely of any success on these older cards…
Ah ha. Did not notice that at first glance on the internet and I was in a bit of a rush so I closed up the card. Anyhow it is not enough space for the newly auto generated VBIOS, as it ended up 140KB.
Is there a reason that soldering a Pm25LD020 chip instead wouldn’t boot (even with stock bios)?
It’s not that big of a deal as I understand. In case the card dies I can just reflash the stock bios through DOS with the right nVidia flashing tools, and if that doesn’t work I will use CHA341. Or am I missing something here?
Thanks a lot for helping. Appreciate your time answering 
It could… but rarely on these old gpu cards generations.
@CannedNoodles
Use the updated links (Today) on the OP
AMD GOP driver 1.70 or MGOP 1.69
Do not flash the backup bios of the card.
Thank you
Some new gop files… Nvidia & AMD updated 2024-06-02
I bought a RX 580 2048 8GB from aliexpress, it was from soyo and had single fan and fan speed was fixed, it was not working with secure boot ON. So i updated the GOP using this guide and it worked. Thanks.
What can I do with these files?
on a rx 550 with modded vbios

[the forum is not letting me attach the vbios files] so

i have modified vbios and evn thought it says i have gop it dosent boot with csm disabled in bios only the default bios works but i need the modded vbios
Modded vbios need csm enabled.
The only way to use uefi boot (without secure boot) is to use magic uefi gop 1.69
You can search it in the forum.

edit : i forgot to mention but i am gettin
The vga card is not supported by uefi driver error whn i try to boot with csm disabled
Your vbios has already 1.70. The only magic gop is only 1.69 version.
The tool can’t downgrade. You need an unmodified vbios that has lower gop version for example 1.68 and then update it with 1.69 magic gop.
okay i did that got the stock bios and applied my vbios mod to it and updated gop using magic gop 1.69 however this error message is there
Do you want to update GOP to 1.69.0.15.50? Y for yes or N for no: y

This is not an error it the same message every time.
if you updated with the magic gop It will work.
If it does not work you simply you update with the original 1.69 gop. You need to find the magic 1.69 gop.
This is my last response to this. I think it is somewhere in the thread.
i ignored the error and flashed nevertheless seems to work
thanks for your work ,where can i download?
