That too didn’t work. No detection of the card when plugged in.
I’ve used the efi part you linked before, thus I have not any more tricks to test.
Thank you i’m still on the hunt to find the initial UEFI for the GTX 580.
Meanwhile i found a different file from another GTX 570 that has UEFI guts and this one is an actual .rom file and not .efi.
570.zip (149.3 KB)
Can the guts be extracted from this file and merged into my file?
“Initial” what do you mean with this statement?
You found another… can you give some detail of the source, notes etc… all the info here is critical on this subject…
A rom with 187k…
Just for curiosity, what motherboard are you performing this tests?

Thank you i will try all of those!
I don’t have much details on it other than someone from another forum custom built one for a 570 and said it should transfer over to mine with a larger chip which it has.
I’m testing the outcome on 3 separate pc’s and they all act the same. It either boots up fine with the stock rom or doesn’t at all with modified ones so far.
I tried all those test files and none of them showed up in Device Manager 
Can that last file i uploaded be merged into my bios?
Hello,
I want to say: thank you @lordkag for this post.
It worked perfectly on the 560 Ti.
A friend of mine upgraded his motherboard, got a F processor (without intel graphics) meaning his good old 560Ti (twin frozr 2) didn’t boot anymore.
Here is what I did:
- I installed his card in the secondary PCI-E slot of my own computer
- I dumped the vBIOS using GPU-Z.
- I patched the vBIOS using gopupd.
- I flashed the vBIOS using nvflash.
Please note that:
-
The 560Ti is a GF114 so I had to use the nv_gop_GF10x rom. It worked perfectly!
-
My own computer is running Windows 10 (22H2) and in order to patch the vBIOS onto the 560 Ti, I has to use nvflash 5.165 specifically, other versions did not work.
Versions that did not work: 5.814 did not detect the card, 5.100 failed, 5.287 with cert bypass failed, 5.412 failed.
The only version that worked is 5.165.

Hi. I’m just about to add a UEFI support to my Gainward GTX 570 and the recent replies are just somewhat about my problem.
It is a GF110 so I chose the GF10x option, but I get this:
There are other ROM images in this binary! Please report it!
EFI is NOT last image!
Fixing ID, last-image-bit and checksum for EFI image.
Fixing last-image-bit in PCIR and NPDE for EFI image.
File “GF110_updGOP.rom” with updated GOP 0x1002D was written!
I’m not quite sure if the new rom is valid (partly because the new .rom has gone from 81kb to 140kb) cause I don’t want to kill the GPU. Help would be appreciated 
Edit: I see now that someone else with GTX 570 in this forum was stuck on the same problem, but I didn’t see any progress he made (at least he didn’t mention it here). Is it not possible?
As you can see in this thread very…very few FERMI bios can be updated successfully with a GOP, the issue here is not the new size because its correct on size increase, we are adding extra data to the main bios, the main issue is if the vbios IC has enough space to flash the new vbios.
Boldy users with some skills can try to get a bigger IC and replace it on the card and even so its not guarantee to work, its all tests…
All this, are risky moves to any user, and only some one that had done this on the same card model can assure you of any successful information, its a user choice only.
If you dont know how to recover and no past experience, do not procede because remotely no one can assure you of anything.
Good luck.
EDIT: Not aware of such compressed version… it would by now be know.
To really get sure of what size the IC is, a visual isnpecction and IC ID is the best.
Usually the size of the dump give us a clue…but not the same as IC ID
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.
Memory Organization
- Pm25LD512: 64K (512 Kbit)
- Pm25LD010: 128K (1 Mbit)
- Pm25LD020: 256K (2 Mbit)
Pm25LD010 datasheet (datasheetspdf.com)
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.
