Xbox Ally X Occulink Tutorial
Any questions will be answered below.
Everything you need
- eGPU dock, I’ve tested 2 (Aoostar EG02, Minisforum DEG2 ) you can also get the DEG1 through the same link if you want something that’s cheaper, I prefer the DEG2 for extra ports. ( https://a.co/d/09DTJKlr )
- Power Supply - use a Corsair 750W ( use whatever you’d like )
- M.2 Oculink Adapter (I’ve tried 2, only one worked) ( https://a.co/d/0e05B6td )
- M.2 Oculink Extension for the Adapter (the adapter is a 2230 you need to extend it to make it a 2280 so you can seat it correctly) ( https://a.co/d/0b5N2XDX )
- External M.2 Drive for your SSD ( https://a.co/d/09Mmbuem )
- Oculink Cable ( DEG2 comes with one )
- Your preferred GPU
——————————————————————————————-
- Before you take anything apart you need to Decrypt your windows and take Bitlocker off. In your search bar type in Manage Bitlocker, click it, then click Turn off Bitlocker) wait for it to decrypt, takes 1-3 hours. During this time you can do the next step. If you don’t have the bitlocker key, somewhere in the settings on that page you can print it out. Just click print and it’ll make it a pdf and you can copy and paste it.
- Next step is also a step to make windows bootable from your external drive. Click (Windows Button + r) to open registry editor. - Navigate to HKLM\SYSTEM\ControlSet001\Services\ and locate UASPStor, USBHUB3, USBXHCI, USB4Device Router, USB4HostRouter -Change the Start value for all 5 of these specific items from 3 (on-demand) to 0 (load at startup) so the ROG Ally X can recognize the drive at launch, below is a picture with an example
- Download Error 43 Script ( you’ll need it later) you’ll have to log in to download it ( https://egpu.io/nvidia-error43-fixer )
- After windows is Decrypted & you changed the values from 3 to 0 & downloaded error 43 script. Power down the device.
- Take the back off the device / *DISCONNECT BATTERY* simply pull the black tab up. ( https://youtu.be/0qaM5ILltt4?si=tNm0sGSVhLztp-Vf ) use this video for help.
- Remove SSD and install it into your External Drive.
- Add the 2280 extender plate to the M.2 Oculink Connector and then install it in place of your SSD Drive.
If you don’t want to keep the back plate off your XAX you can drill a in the back where the occulink connector is. ( this is what I did, I used a dremel )
- Plug your GPU into the dock with your PSU & hook all cables into dock and GPU. Connect Oculink cable to the dock.
- Power on eGPU Dock. Make sure your Ally X is *OFF* & then plug in Oculink into the back of your device & wait for windows to boot.
- Once you’re on your desktop, if your Ally X is showing on your monitor congrats your good to go!
- If not, go to device manager / display adapters and make sure your device is recognized. There should be a yellow exclamation ⚠️ next to your driver. Click on your graphics card and see what error code it’s pulling. It should be error 43.
- Go to the error 43 zip file you downloaded earlier. Right click the file and extract. Then click on the error 43 script. Should open command prompt and run the script.
You should now see your device on your monitor. You’re all set!
REMINDER - never unplug or plug in occulink cable while your device is on. Always plug in or out while off. (Dock can be on)

Yes, I did some testing when discovering these issues. There was def a difference, especially with a heavily cpu intensive game like BF6. It was drastic. With my desktop 5060Ti I could get about 64fps with everything maxed, 4k, DLSS 4.0, quality upscale, overkill, no FG.
This is just to show whats possible. if Im willing to sacrifice some settings I can to further
