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

Beat my expectations. This host adapter is at the heart of my retrofit of an old thunderbolt eGPU into a much faster oculink box. Ran the PCI-e bandwidth tester and verified it was averaging 7.05GB/s (60.6gbit/s). Tried it with 3 different machines (using the m.2 slot on a framework laptop, as well as the on-board oculink slots of both an Aoostar gem12 8845hs and a GPD Win Max 2 8840u). It ran perfectly on all 3. $40 very well spent.

This is no less than the sixth product I've tried looking for a way to run multiple PCIe 4.0 U.2 SSDs from a bifurcated PCIe slot. All of the other products worked fine at 3.0 speeds but would cause a stream of AER logs, resets, and whole-system hangs at 4.0. All of them.Not this one. Four drives, buttery smooth at PCIe 4.0. Gigabytes per second per drive.I used the corresponding Oculink 8i to dual-U.2 cables from the same vendor to connect drives.

Works to attach GPU to get video from my Asustor Flashstor FS6806X NAS.

I did have to 3D print some adapters to let me secure this to the bracket I purchased, but it worked without any issues. I tested both a PCIe 4.0 SSD and GPU. Things have worked at that speed so far.This seems to be a really good value for the PCIe x4 board, Oculink cable, and M2 Oculink adapter.

Y'know it's weird, gpuz says it's only running at pcie 3.0 x4, but the real world performance gains I'm seeing from using it with a used 6700xt i got for 250 instead of my laptops mobile 3060 is craaaaaazy. I can finally play half life Alyx comfortably, and max settings at that, every game I've thrown at it runs at 100fps or more on my ultrawide 1440p monitor with max settings. I bought an open pc case on amazon that interfaced perfectly with the mounting holes on this board and it feels super sturdy. I never could get my gtx 1650 to work with this board (driver issues and many BSoDs) but it was nearly hitchfree using AMD. I just had to disable the igpu, install new drivers from amds website, then re-enable the igpu, absolutely no problems. To cut the hole in my laptops casing I used double sided tape to mark the spot then carefully cut with a dremel. I filled the port with painters tape then filed it down with my dremel so it doesn't stick out too far, worked like a charm!Incredibly satisfying purchase, and i feel like such a giganerd having this thing. JUST DO IT!!

I needed this to set up 2 U.2 drives in a PC. Long story short, it only did 4x2x on the first slot. I did not test the second slot as it was in an electrically 8x slot. Bought other cables to rule out the issue as well. Was a frustrating evening. I'd stay away if you are trying to do that config.

The M.2 card makes a crap ton of noise, pretty annoying, and if it was near my WIFI card it would probably mess with it. Other than that, it works fine.

It was a little fiddly and there were no real instructions. Works only after setting up a second monitor and a reboot. This is really the only way to do an eGPU faster than usb 4 and thunderbolt 4
