Hi everyone,

I have an Akitio2 that works well when only using one GPU for mining. I thought I might try using a PCIe riser with it that are easily purchased on Amazon to expand the number of x1 PCIe slots that the Akitio2 can control.

I am using the PCIe riser that has one USB-like port connected to a board with 4 x1 PCIe connectors on it. I do not know if the board itself is working and will probably try it on some of my TB3 enclosures when I get a chance to see if they have any better luck. I do know that the PCIe riser board is powering the GPU just fine (an old GTX 980). Windows 10 does not see anything that I can tell. I double checked the connections. I also verified that Akitio2 itself still works by just plugging the GPU directly into it again and it loaded as usual.

Has anyone tried to get the Akitio2 to work with something like this? I assume it should work fine. After all, Akitio claims that this enclosure is NOT supposed to be used with GPUs (lol) so what could be wrong with a PCIe-PCIe bridge?

Thanks!

Hey again,

I think I answered my own question. I don't think the Akitio2 plays nice with anything other than a GPU. I wasn't sure if it was the Akitio2 or the PCIe riser I bought on Amazon for $50. I doubted the brand new PCIe riser that has virtually no functioning parts save a couple connectors and a USB 3.0 controller was at fault.

To test the PCIe setup I decided to try it on a newer TB3-based enclosure. I attached the PCIe riser to a Razer Core X Chroma by plugging the PCIe male side into the Core X Chroma and just routing the USB cable out the empty slot (the male side is 1-wide and the Core X Chroma is 2-wide slot). I am using an 11" MacBook Air mid-2012 w/ TB1 (with a TB3 adapter) to test the riser and it works as expected (effortlessly, lol).

So.. if in a pinch, you can use a Core X Chroma as a mining rig with a cheap PCIe riser off Amazon. Also, I am not a huge fan of the single-board PCIe riser since it does put the cards relatively close together. I am using a Nvidia GeForce RTX 2080 on it which is 3-wide and is WAY too big to fit on this little board. It really can only handle 2-wide sized cards and at that they are only about a 1/4" apart.

Here are some pics of the strange setup and it working. The Macbook Air is loaded using WintoUSB and the screen is always black when running eGPU.

Good luck out there!

Additional note.. 

I had some issues attempting to get my MacBook Air to handle multiple GPUs with this setup. I think the system may be a bit too limited on resources. Most attempts to boot would get the ACPI_BIOS_ERROR BSOD. When Windows would load, the Nvidia GeForce RTX 2080 would load fine but attempting to add another card (GTX 980 for example) would have a code 12.

I attempted workarounds by disabling IRQs (mostly the HD Audio Controllers), increasing page file size more than adequate and some registry edits to no avail.

Maybe I will try some more things later.

nice work keeping a detailed sequence here of what you have tried and are trying to do. I would say two things. First, you will probably at some point damage your CPU unless you adequately monitor and control the temps... because you are using a laptop I say this. Second. This setup seems like it should work based on stuff I've read on this site and elsewhere (but you are definitely doing some pioneering). Maybe focus on max 2 GPUs for now(?) I'd recommend not mixing different series of nvidia cards - stick to 10 series if you can. Also, does windows 7 support any eGPU? Good luck.
