This is a placeholder post for proof of concept, testing eGPU limitations via Thunderbolt 3.

TL;DR:

- Save your money and buy the right components

- You will not be able to spend less than $1000 once you cross the single GPU eGPU territory

- Buy a laptop with an unlocked BIOS, or can be flashed with one - it's the only way to completely get rid of error code 12

- There is no benefit to having more than one GPU for gaming due to Thunderbolt bandwidth limitation

- No SLI

- Despite the above, for hash decryption at least, a Thunderbolt eGPU can go toe to toe against a traditional server, due to GPU optimization and less reliance on number of PCIe lanes and bandwidth.

- The Cubix is only 1/3 larger than the Aki Node

- You can stuff a 2 double wide slot Cubix with 3 full size GPUs (one 1080, two 1080 Ti) with room to spare for Aki Node controller board

Nice work.  There's definitely a market for multiple GPU enclosures.  Price needs to come down a bit.

I think you can use this adapter instead akitio board and host-card... It can be more universal

Onle i-pass PCIe cable is needed, like this

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

No. This x8-to-x8 cable. If you use Sonnet adapter, you'll need x4-to-x8 cable.

x8-side to Cubix and x4-side to Sonnet adapter.

PCIe cables 448x298

By the way, I did order a Sonnet SE 1 before, which should have the TI83* controller, but unfortunately, did not work with the Cubix.

That was when my laptop BIOS was still locked however. I will try your recommendation once the Sonnet DX adapter becomes officially sold by Amazon (for free return shipping if it doesn't work).

*TI83 is necessary for devices not officially certified to work with Thunderbolt.

One clarification: it's a TB2

Needs an adapter for the adapter- Lol

At least until a TB3 version comes out.
