iM 4,1-14,4 2011 iMac Graphics Card Upgrade

[Pacific1972]

well, after more digging and reading, i found a site that had more to say than here on how to use the code.

2009 - 2011 iMac +Metal GPU Upgrade
which led me to this pic on how to properly enable the code

also found out that the amdvbflash in the november blues file is too old. couldn't handle the -f string. once i updated that, then i was able to properly input the code.

now for the fun part, over 10 different files for the wx4150 dell card all gives me the same result. showing 14 mb

after several tried with different roms, this is what my screen outputs.

gave the reboot command, even reset pram like i read in some spots. still no difference

i will upload my original backed up rom here to see if anyone can make heads or tails of it. it seems to flash in ssh, but i'm not getting a proper picture.

WX 41X0 - iMac GOP ROM

...what kind of 10 different files do you mean ? There are not soo much different Apple ROM
versions for WX4150 available ! Do you have made photos of your GPU card (front & back) ?

Perhaps I don't can help you, but sometimes there are some conflicts with the GPU
(but normally no Sleep/Wake or SMBus problems) on iMac 2011 with Socket 1155 CPU
- also I think the GPU have a short circuit with clamp, screws or cooling element,
connected to the housing of your iMac or other electrical components inside...

Hopefully you don't buy this glitched GPU scrap from an "anonymous" 😁 AliExpress seller...

According to your original VBIOS your card is a WX4130 with only 2 GB of VRAM - so try flashing one of the WX4130 rom files.
In case you have just replaced the original graphics card with the WX4130 you also have to make sure you remove the OCLP post install patches, because the patches for the original graphics card do break later AMD/ATI drivers. After removing the patches you'll have to reapply the patches using OCLP.

from all the downloads i was able to find, i was able to gather around roughly 10 4150 gop roms, but they could be doubles too. so i was checking each one to see if it made a difference.



also, i had a proper desktop before flashing, so oclp did see the card, just showed "Display 14MB" in ASP with no drivers loaded

also no aliexpress, was a legit ebay listing from the states

odd, since the listing of the card states its a 4150. i guess i will get on the horn with the seller.
i did remove the root install patches, reinstalled new ones and did pram reset. pics posted earlier are the result.
can you send me the info on that rom so i have something to show the seller?

 

[reddrag0n]

i think i'll flash the original rom file back and do the old windows cd install trick i have done with other imacs and see what windows will show. then i have a fighting chance on how to respond to my ebay seller

 

[reddrag0n]

ok, so flashed original rom file back and no video on internal display, but external shows properly. just like it did when i first installed it.






AHA!!!!!!

 

[reddrag0n]

ok, got more info on that card, and you are correct, it is the 4130 model. i sent the seller a message saying that he *&$^**&^% up.

 

[reddrag0n]

ok, so installed the 4130 gop rom and i am back at the same spot as before. reinstalled root patches, rebooted, reset nvram and still saying display of 14mb

didn't work - WX4130GOP.rom

trying other 4130 roms that i found.

didn't work - WX4130_EG2_adj.rom (boot loop saying need to recover hard drive)
didn't work - WX4130_EnableGop_ALT.rom (only shows 14MB)
WX4130_EnableGop.rom
WX4130-EG2_adj_ALT_VRAM.rom
