chenyang Oculink SFF-8612 to PCI-E 3.0 M.2 M-Key to SFF-8611 Host Adapter for GPD Win Max2 External Graphics Card & SSD

Really happy with this purchase, it comes with the oculink cable and wifi slot to oculink connector but I bought another one with extender through the nvme slot. Much better than the noisy overpriced Aoostar. The build is combined with RTX 5070 and Corsair RM750e modular PSU for a clean build. Zero noise build, the fan only goes up if temperature passes 50 degrees Celsius. The GPU is turn on and off according to the laptop power state. Plug in, Power up, Install latest Nvidia Driver, Gigabyte control center, code 43 script. I write low level CUDA for a living, so here’s some extra info: - nvidia-smi shows 2 GPUs (my original laptop GPU rtx 3050Ti and this one) - 2 GPUs can communicate through PCIe, I tested a NCCL code for vector addition on 2 GPUs and it worked. - CUDA Code can compile with sm_120, and run no problem. Pytorch recognizes 2 GPUs and set the 5070 as GPU 0. Nsight compute works with debugging and uses 5070 if the code is compiled with sm_120.

To avoid any confusion I received the full package of M2-Occulink adaptor, Occulink cable and PCI-E to Occulink board (I noted some confusion in other reviews over what was expected vs received). This is working exactly as expected with my 6800H based mini PC and ARC A750, ReBar is even enabled(!). I had to get a little M2 extender / adaptor for my build but if you have a spare 2230 slot this is perfectly compatible. Great value for money as long as you don't mind a bit of "jank" in the overall setup.

Decided to try this in place of my thunderbolt 4 connection, I was blown away by the performance increase! AVG 30-40 FPS increase with my Arc B580 and all my in-game stutters were gone. If you have a spare M.2 SSD bay I highly recommend using this, paired with a cheap 500w power supply and my mini pc it makes for a great way to play games.

Dell 3070 Micro MFF now has an RTX 3050 thanks to this and an ITX PSU, Works fine. I used a 2x sata to one 8-pin converter for the very small additional power needed by the GPU.

Really good for DIY oculink EGPU. Works really well. Well worth the money.

It works perfectly with the Dell Optiplex 3070 micro with 0 issues using the gtx 1080.

I ordered the whole kit which shows the host board, m.2 connector and Oculink adapter but like other reviews have said I only received part of the kit! All I got was the host board and nothing else

Ended up getting sent back as wasn't compatible with Rog Ally
