Are you sure you are not hunting down the hash mismatch problem?Please upload the original VBIOS - or post a link to the post where you had uploaded it. I'll check for differences.

and where is that rom?Hello!
Having a similar setup and currently no issues with the boot picker and the choice of other OS versions. I use macOS Catalina and Mojave and Windows 10 UEFI (once in a while). You tried the magic PRAM reset, which you probably once made to enable the card after installing it (this is just a guess, because I have really no other idea).
The card works even with the OpenCore boot picker I am using because of some other experimental stuff...

YOU are insanely great! Updated the first post...
On the very first post in the very first page there is a table with all NVIDIA cards and all vBIOS versions posted. Check your card which VRAM model you have an pick the correct vBIOS yourself.and where is that rom?
Check my earlier post of this exact scenario with WX4130 which could possibly be due to chrome. It fixed the issue upon removing chrome for good.I am observing unregular black screens/crashes with iMac 11,3 and WX4130. Currently I cannot determine if this a sleep/wake issue. Still observing it. Sometimes the system is very stable over many hours eg. a full day (even under high stress like doing the Valley Benchmark with ULTRA Settings with max. temp in the area of 85-89 degrees in peak from AMD GPU, heatsink and ODD sensor at 50-51 ....no outage). Sometimes, with no load, suddenly I have a black screen out of nothing. It's a real crash as I cannot connect from second iMac via network or desktop sharing. Any known issues or hints what this could be?
EDIT: I am using macOS 12,1
OpenCore does not enable brightness control in Windows, only within macOS. You have to manually edit the Windows drivers as described in this post, but it does not work in any case.Hi, I'm looking for a Guide to build a SD with OC. (iMac 2011 i7 - GTX770 by Nick -SSD MX500)
I use it in W10 and I would like to return the brightness control.
Thanks a lot
YesHi all. Amd Radeon Pro WX 4150 will work with iMac 2010 11.3 27inch?
Curious if sleep works on the iMac12,2? I'm in the market for a card and it would be great to get the most performance possible for under $200 with working sleep. WX4150's seem too pricey for what they are and the M5100 is cheap but underwhelming. Looking forward to more progress and the final BIOS.W7170M

Honestly, every search machine would have give you that answer, too!
Please start reading on page one and post #1 - according to this post and the information there the green Dell WX4130 cards should work in each iMac model.Hi all. Amd Radeon Pro WX 4130/50 will work with iMac 2011 12.2 27inch?
is it right?
Thank you very much for your reply.OpenCore does not enable brightness control in Windows, only within macOS. You have to manually edit the Windows drivers as described in this post, but it does not work in any case.
Check the first post about OpenCore and OCLP and use it to create an SD card in case you run macOS.
