X4 M.2 EGPU Adapter

Hiya All,
I tried dropping an M.2 Oculink adapter into the M.2 slot on an X4, which I’ve sucessfully used on a Panda, and Odroid boards.
The gpu starts and stops with the X4, but it’s not seen by Windows 10 ( or 11 for what it’s worth )

I’ve also had an M.2 SSD in the slot and it’s great.

I did some searching of the Forums and it seems no one has asked this question, which makes me think I’ve missed the point here and it’s a dumb question, but my question is not why doesn’t it work, moreover, should it work…

Hello Matt
Which M.2 Oculink adapter using? Can you show how to connect them all?
We haven’t tested oculink, but we assume it should work and we’ll verify it.

Hiya, Thanks for the confirm. Indeed, once I knew it should work a bit more tinkering and it came up easilly.

The embarrassing truth is that what I failed to realise is that when an external GPU is connected via the M.2 Oculink adapter both the native HDMI’s stop working. This is not what I’ve seen on other boards and when I patched into the 4th output of the 3080ti I was using ( because it’s the only HDMI connector ) it didn’t work either, so I immediately dismissed this diagnostic step. What I should have done is dig out a DP to HDMI adapter and try the top DP output on the 3080ti first, whaick worked instantly.:grinning:

Here’s the adapter I’m using -

Here’s a quick benchmark. I know it’s not exhaustive, and there are many factors to consider but my £90 ( with Heatsink ) X4 does this

and my £200+ Latte Panda Delta3 does this :

Oh, and BTW, during the test the X4 CPU temp peaked at 62 degrees.

Sorry to brief, wanted to update quickly and have a busy day. Thaks all for a great community, I have Rock 4 and 5’s too and love the Radxa products, community and who cares if there’s the odd empy zip file occasionally :rofl::roll_eyes::sunglasses:

Actually one fina thought, If anyone was to do this, you might want an oculink cable like this

Because of this

Hi, sorry for the silly question, but with the M.2 M Key slot occupied by the chenyang Oculink SFF-8612, did you boot Windows from USB?

Can you, please, explain to me your setup?

Thanks a lot

I think Windows can install on eMMC, or it can boot by win-to-go from usb disk
