2011 iMac Graphics Card Upgrade 5500XT 8GB records

[lyf314512]

1、I got an AMD RX5500XT 8GB mxm graphics card, after installing it on imac 2011, the two external monitors connected with minidp can be used normally, the DELL UP2715k 5K resolution monitor can be used normally, the native monitor is always black, the graphics card performance is 30% higher than the wx7100.
sorry for using translation

2、By modifying the hardware of the graphics card, the internal screen can be successfully turned on on other mxm laptops. After passing the stability test, I will install the graphics card on the imac 2011. Perhaps the internal screen and two minidp interfaces can be enabled normally by oclp booting.
If all goes well, I will install the strongest AMD card rx5700xt 8g on imac 2011

3、After a few days of testing, the 5500xt is already working fine with the built-in monitor on the laptop. Next, I'll test the imac, there may be surprises.

4、After many days of testing, the 5500XT 8G has been able to start the internal screen, which is a miracle for the old IMAC, and it will become the only computer in Apple products that truly travels through time.

5、The exciting time has come
1. After using OCLP to guide the macos12 Apple logo progress bar, the screen has been black, and the system login interface cannot be displayed. If anyone knows how to solve it, please help me.

2.Using OCLP to guide uefi win10 can enter the system normally and use it normally. The exciting thing is that both miniDp ports can be used, and both support 5k monitors, because I only have one 5k monitor, so I am not sure whether to support simultaneous points Light up two 5k monitors. At least it can be confirmed that it supports one 5K and one 4K monitor at the same time, which is much more powerful than the WX7100 can only support one 4K monitor.

6、I uploaded vbios under someone's kind reminder, but don't be misled by vbios, because the RX5XXX series vbios have encryption and cannot be modified by individuals.

7、WX7100 8GB VS 5500XT 8GB

8、The inner screen is finally displayed, but the resolution of the outer screen is not displayed correctly.

HI lyf314512, that's exciting, can you also share what hardware changes you did to the x5500xt to enable internal display? THanks.

Very interesting project! Any updates?

How is the situation now? I also want to upgrade. A buyer in the seafood market issued this card, but did not provide any technical support. I hope you can share your experience, such as the renovation of the radiator, whether to brush the rom, and the problems encountered after installation, etc. Thank you.

A quick note about the post above: It was originally posted in what I believe to be Chinese, and it looks like it's been machine-translated with a few quirks (radiator = heatsink, brush = flash, although "seafood market" is a bit of a mystery to me!).

In China, there is an application called "free fish", which deals in second-hand goods. We usually call it seafood market, hahaha~~

Hello, I am from China and my message was translated by machine..

My machine is the 2011 A1312, and I also have the 5500xt graphics card. After flashing the firmware you released, I ran Windows 10 normally, but there was a problem where it turned into a shutdown after sleeping.

I don't know if your condition is normal, how did you solve it?

Can you share your OCLP configuration?
