I was wondering if there would be a Oculink expansion bay for the F16.  
The gpu module is connected via atleast PCI4.0x8 right? Meaning you could have 2 oculink 4.0x4 ports. I really like a software called looking glass i use it alot and it makes VM’s very convinient([looking-glass.io](http://looking-glass.io)) and it recommends a dual dgpu setup.  
And from testing with a igpu before i agree. Would also be cool to have a switch and switch between like a oculinki4 or i8 port so maybe connecting 1 gpu via x8 becomes possible.  
I read about diffrent connectors besides the oculinki and i8. I don’t know if i8 to pcie x16 slots are buyable. Anyway just wanted to start this topic.  
I saw the i8 topic in a diffrent topic already but i thought i make a post regarding Looking glass.

Not sure if this topic you saw, but I thought I should point it out in case you haven’t seen it.

The Expansion Bay module is sized in a way that it’s possible to fit an OcuLink receptacle in it, so a mostly passive adapter board is probably possible. This is assuming sufficient signal integrity through the full chain of connectors and cables, but it would also be possible to stick a redriver on the card. This probably isn’t something we would build ourselves, but all the necessary parts should be available in small quantities, and it…

In that topic, [Seneral](http://community.frame.work/u/Seneral) has posted designs for a Oculink expansion bay module. And I believe [Josh\_Cook](http://community.frame.work/u/Josh_Cook) also said he plans to make a version as well.

There exist cables that convert 8-lane oculink to dual 4-lane oculink.

Framework has published a lot of information on their github, like the expansion bay pinout. Looks to be 8x PCIe.
