Hello, I just purchased the Razer Core X Chroma and the Sapphire AMD Radeon RX 6900 XT Nitro+. I would like to connect this to my 15" 2018 MacBook Pro. I booted to windows, and the GPU is connected, I try to install the drivers, but the fans don't start to spin. While booting up the case fan once started spinning for 2 seconds. The LEDs work, and my Keyboard and everything connected to the GPU enclosure works, there's no output to the 2 Monitor connected. I would love to get this set up to start streaming, but for some reason it won't work. If this isn't too much to expect id love it if someone can help me set this up. Thanks Smile

Edit: I'd love to use the GPU in macOS sometime, but I know the GPU isn't supported yet so i'll wait till it is unless anyone of you has a different solution.

Edit 2: I noticed why the GPU fans werent spinning the Razer Core X Chroma has the 6 / 8 Pin connectors, to turn them to 8 Pin you have to sorta clasp the 6 Pin and a 2 Pin together, My 2 pin wasnt in correctly. The GPU now spins, but the issue still stands, i just tried installing drivers, and it still didnt work. 🙁

@appleluis, Check our build guides for 2018 15-in MacBook Pro with Radeon cards. You'd need the modified Radeon drivers from bootcampdrivers.com to use both dGPU and eGPU.

@itsage, Hi, thanks yea i figured it out after all. The Razer Core X Chroma has 2 6 pins and 2 2 pins that you need to connect to the 6 pins in order to make 2 8 pins. The 2 pins werent in correctly so it didnt get enough power. It works now, im just experiencing extreme power loss. I might open a new thread. I mean Im getting 60 - 100 FPS on MINECRAFT with the worst settings, no texture packs or shaders, and just 32 chunks render distance. Once i turn the Graphics on high (still no Shaders or Texturepacks) I only get about 40. I know that there is some powerloss with an eGPU but come on. A 1500$ card gets 40 FPS thats like 90% power loss. Im gonna open a new thread about this and hope that i can get help somehow. I installed the correct drivers and everything works, but there is such extreme powerloss that i dont think i could stream or something.

@appleluis, Please start a new topic so that we can get others' feedback on the RX 6000 series graphics cards and the drivers currently available for them. Due to lack of supply, many people (myself included) don't have our hands on these cards to provide much input. My observation of Radeon drivers in the past few months has not been very positive in terms of eGPU performance. The only version that produces good eGPU performance for me is 20.4.2.

@manu89ft, Simply run DDU to remove all AMD Radeon drivers then restart. You can proceed to download and install the latest Radeon drivers from AMD website. The stock drivers would only recognize the eGPU and not the dGPU. Internal display (powered by dGPU) will be sluggish due to no drivers but external monitor connected through the eGPU should have full acceleration.

Are you saying if I don't need to use my dGPU (5500M on MBP 2019 16" 8GB) and ONLY want to run my eGPU (AMD 5700xt OR soon 6900XT), I only need to DDU/remove all/boot normal/install genuine AMD drivers fresh from their site??  I can swear I tried this and it told me no hardware was detected... do I need the EFI bios for that?  Or did I miss a step?  I run with my lid closed...

@erik_tank, Yes, the stock drivers from AMD works with standard PCIe cards but not dGPU in Macs. Windows would use its default drivers for display output but no acceleration on the 5500M in your 2019 16-in MacBook Pro. Thunderbolt 3 eGPU detection is another issue altogether. You can try hot-plug into different ports and see which one produce proper detection then install the drivers. Depending on the Windows 10 version you're running, you may need EFI boot loader to cold boot with the eGPU attached.
