adding a rx 6400
Hello.
I have a little optiplex 7050. i7 with 16 gigs of ram also a mvme. So I got myself a low profile rx 6400 so I could turn it into a light gaming machine for the kid.
I assumed I would be able to just drop it in and it should work. When it is in the machine seems to stop early in its boot sequence. Before it start loading up the OS. If I hit f11 f12 I get a little message at the top right of the screen "preparing one time boot.... something or other" and stop there. Please note. I can only see this if the HDMI is plugged into the onboard output. Not the rx 6400. It just give a blank screen on the card.
Now I know the card works because I put it in my rig to test. No problems.
I updated the bios and all the drivers. Sooooo ya, Any thoughts?

I have a 240w psu. I upgraded it for the graphics card.

One other thing I can think of - Try turning off Secure Boot in BIOS.

- Hey revelationsr, I see you came from ETA primes build on YouTube, I also am having issues. Any chance you can post what BIOS version, and AMD driver version you are using for this to work? Thanks

@ J0nny88
Yes I did come from ETA prime. Love hes channel.
I had to play with the Bios quite a lot. There are some oddities when working with the OptiPlex. The 2 settings that seemed to get me past that issue was to turn off secure boot as well as legacy options roms needs to be on.
I am assuming you still need to install the OS. I would recommend leaving the rx6400 out of the machine until you finished installing windows. For some reason the rx6400 is putting out a odd resolution during installation that only 1 of my 3 screens understood. If you screen supports it then great.
I was surprised by how unusual the setup for this little machine was. Lots of little things that pops up and needs to be researched to move forward. That being said if I was to do it again now I think I will have the OS and card running in about 30 min.
Good luck!

Hey, thanks for the heads up, I too was having the same issues on my Optiplex 5050 SFF and these steps enabled me to get a picture out. Unfortunately I was having another quite significant problem - the heat of the Card
Can you tell me if your gpu was getting unusually hot to the touch.?
When installed and after only a couple of minutes, mine was so hot I have returned it for a replacement. This was at Idle and even before it had booted into windows. I'm hoping I just had a defective card as I am really excited to have this up an running in my Optiplex.
I would be interested to hear your experiences and comments.

I want give a big a thank you to you! I also watch ETA Prime. I bought a Dell Optiplex 5050 SFF, a 240w PSU from a 3050(mine had a 180w), and a Sapphire Pulse RX 6400. I couldn’t figure out why the GPU was not displaying and I came across this forum. Surely enough your suggestions worked and I was able to fully install the drivers.

After receiving a replacement card and following the steps mentioned I have successfully installed all drivers. Thanks again

53w GPU is likely too much for a small 180w PSU.
