You have installed the Legacy Video patch from @dosdude1. Install Catalina again following the guide posted on post #1 and page #1 for Catalina on iMac 2010.
Hallo again!
Thanks for your help a few days ago.
I got my 2010 21.5 iMac with a HP WX4150 up and running. Everything is fine. Except one major problem. I can't install my SSD properly.
The iMac only starts with the SSD attached to USB.
Things I've already done:
- using a 1mm copper plate on the die.
- covert the whole graphics card with electric tape.
- looking for shorts.
- installed the card without heatsink
- changed the SATA cable
- installed the old card. Works without any problems
- tested another SSD and a HDD
Always the same. No problem starting without connected SSD/HDD. Doing nothing with connected SSD/HDD. No Fans. Nothing. With connected SSD only the first LED is on. Without the SSD the first two LED. With LCD connected and Mac OS started from USB LED 1,2 and 4 are on, and the system is running.
Any ideas?

There are two plus a half possible explanations:
1. Your logicboard got an electrical shock and is damaged (I have a 2011 acting exactly this way with some known to be good NVIDIA cards). I can use card+ssd without internal display. When I try to uses all three parts (SSD+GPU+LCD) I get your problems. Had a failing power supply in that particular machine burning a big cap and made the fuses of my lab react.
2. You found another of this funny HP AMD cards we warned about on the first post not really compatible with our iMacs.
2.5 The SMC and/or NVRAM is confused and needs proper reset. (less likely)

Bonjour,
I'm soon about to test this possible problem by doing a High Sierra installation on another machine (not successful with mine) and test if we can force an update of the EFI and hopefully of the SMC, I'll keep you informed.
Ps: Besides I have my SMC in 1.71f21, I thought it was 1.71f22 !?
SMC Version (system): 1.72f2 on both of my currently active 27" 2011
Readed Post from @highvoltage12v How to fix 2010/09 iMacs which have been patched with the "Legacy Video Card Patch" from the Dosdude1 installer. After Unloking System Locked Files and trying to replace OpenGL Folder I Getting -8062 Eror. I Used Hacktool. I Tried to unlock via terminal is same. SIP is Disabled.
I think it's No.2. System is working flawless with the old card. I don't think the logicboard is damaged. Also I bought the card from the ebay link someone posted in this thread and it seems to be a new card.
I think I will test another card. Problem is you're so limited with the 21,5 iMac. Nvidia K2100M might be the answer. What you think?
Mine is [SMC Version (system): 1.71f22] | iMac12,1 (iMac 2011 21.5")
Does that means our systems needs an update?
Please, reinstall Catalina. Your data will remain untouched unless you delete the partition or container.
Experimenting with AMD cards is sometimes annoying. Usually I start to test in the Late 2009 and then move on to the 2011. Even then we found a lot of cards not working at all or only in 2009/2010 with i-Series CPU.
Normally a K1100M is really fine, the K2100M gives you the same power as the 6970 on a smaller panel - effectively you would have a better performance...do you need this?
Ask or better search this on the thread about your macOS version
This is the GPU thread.
I had the idea before reading your message N°#12,407
It made me want to try an upgrade and update SMC, but am I doing this for nothing?
I was going to do it anyway if it helps.
Bonne soirée!
Hello, I'm new to the forum. I just installed the Nvidia K2100m with Elpida VRAM. I flashed the Bios using a CH341A programmer with nickey22 rom file for the K2100M with Elpida VRAM (ROM 2). I have a 21.5" iMac, mid 2010 and I ran Valley and I'm getting worse results than my original GPU or my K1100M GPU. My results are 11.4 (5.4-25.1) FPS. I'm thinking I did something wrong when I flashed, or missed something, or got a bad card. Any help will be most appreciated.
I don't need the better performance. I have a Mac Pro for work. My wife needs the better performance for Sims 4!
I'm not new to the Mac world and I've repaired a lot of machines. So I think I know what I'm doing. The more it's stressing me out not findig a solution for the WX4150. Because it's working fine with the SSD hook up to USB. It must be a power problem, because the Mac is doing nothing with connected SSD. After disconnecting the SSD I have to unplug the power cord and plug it in again to start the iMac. Seems like the power supply is shutting down completely.
I checked the layouts and IDs. I have exactly the same card as Nguyen Duc Hieu #9,712
Time will tell if I find the bug or have to buy another card.
You are doing an SMC reset with pulling the wall plug. We are observing only the problems at the surface but this weird SMC we had back in May with several HP 4150 cards. Being not an expert I honestly do not know what causes it.I don't need the better performance. I have a Mac Pro for work. My wife needs the better performance for Sims 4!

Please search back the thread, had this myself and another user some month ago. The combo 21.5 2011 and K2100M can cause such problems but there is a cure.

I'm not sure whether or not we had reports of successful installations of a WX4130/WX4150 in a 21.5" iMac 2009/2010 at all. Maybe they work in the 27" models only?I don't need the better performance. I have a Mac Pro for work. My wife needs the better performance for Sims 4!

Internetzel, you are right.
I looked thru the performance tables.
All reported success with benchmarking in 21.5" iMacs are using nVidia GPUs.
So, I do think Floatation achieved a milestone in having a WX4150 running in his 21.5" iMac 2010.
Being able to flash his GPU and get his card POSTing is an important step.
He was able to have an internal display with an external dongle or display connected. That partly solved the display problem / black screen problem despite not a clean solution but just a small compromise.
With the GPU installed, SSD can't be connected and booted from. It appears to me to be a power issue.
On monitoring the power consumption of my GPU with iStat, I noticed on & off significant power hype even with usual internet browsing. It is possible during booting, the initial power surge on cold starting (GPU + SSD) may overload the power supply and prevent the normal POSTing and booting. Also the 5V supply line to the SSD could be stressed if it is also utilized by other components. I can only conjecture that the USB interface may dampen the power surge or has more power juice in the internal wiring if it is not shared by other USB devices. How about disconnecting the DVD drive to see whether enough power can be available to remedy the situation. Just brain-storming as I am not a computer technician
Besides, the Mac vBIOS of WX4150 is overclocked. I am not certainly whether by downclocking it or adjusting its power curve table would reduce the current requirement during operation.Certainly his WX4150 is working and can be sold for some value to other users in need if the project is abandoned

I managed to score a lucky WX7100 through Facebook marketplace from a guy who fried his logicboard before even installing the GPU.
I paid $50 AUD ($38 US)! I thought there's no way this is gonna work - low and behold it worked perfectly!
Booted black screen into Windows > Remoted into it and flashed the bios on page 1.
Now to finish up with OpenCore.

You got a jackpot, man
i was never able to get hold of a WX7100.
And it is really expensive in the market (>$300 US).
So, I settled on my RX480 which is pretty decent in performance.
What is your setup?
Maybe the first post should be edited. I will do further testing. It's really weird.
