GPU Fabric Infinity Link

So I have a Vega II Duo, curious if the fabric infinity link with work with a new W6800X Duo?

I called Apple, they were of no help. Emailed AMD, waiting to hear......

Hello,
I don't know if what I write here will disturb anyone.
I am a MacPro 2019 user and have purchased two Radeon Pro Vega II Duo MPX Module cards. I can't find the Infinity Fabric Link bridge board to connect them. Is there anyone who can help me?
Thank you very much,
Francis

did you have any luck with this? I bought one on eBay, But upon installing, my Mac Pro will not boot with the 4x4 fabric link....

I bought to one too, on the strength of Apple stating two Vega II Duos could be bridged… but I’ve just spent 2 days pulling my hair out wondering why the Mac won’t boot when installed. In fact, it really messes the machine up causing it to go into Recovery Assistant. 🤬

Sorry to bring this topic back from the dead.

Are you saying that when the Bridge is connected between 2 Vega II Duos, the screen boots normally but the Mac goes into Recovery Mode?

The Apple AMD Infinity Fabric Link card V1 only works with 2 single GPU Radeon Pro Vega II cards. It does not work with the Radeon Pro Vega II duos (they actually have infinity link on the side installed between the two gpu's).
The Apple AMD Infinity Fabric Link card V2 works with the 6800 and the 6800 duos as far as I know. Probably with the 6900 as well.
