Minisforum MS-01 compatibility

[Doug411]

I have a Minisform MS-01. It has the following B&M key NVME slots

M.2 2280 NVMe SSD slot (Alt U.2) (PCIe 4.0 x4): One slot
M.2 2280/22110 NVMe SSD slot (PCIe 3.0 x4): One slot
M.2 2280/22110 NVMe SSD slot (PCIe 3.0 x2): One slot

Would I be able to use the dual edge TPU with your b&m adapter in the 3X2 slot and have both TPUs recognized?

It also has an e key for wifi/Bluetooth. But I believe I read that it doesn't support bifurcation.

I'm using the 3.0x2 slot and have both TPUs recognized and they work perfectly.

However, the tricky part is that there is not enough space under the SSD fan to fit the adapter and the TPU card, I have to raise the fan and cut a small piece of the metal plate to fit everything back into the chassis.

[Doug411]

What inference speed are you getting?

UGH... How did you raise the fan? I'm trying to visualize why you would need to cut the plate. Is the plate too low as well?

Im visiting in a location where I don't have my tools. What did you use to cut the plate?

[Doug411]

oh, and how did you raise the fan?

[Doug411]

Also what do you think of using an extender? Do you think there is space to reroute a little? I wonder if the 3X4 extender would work in the 3X2 slot?

I get 7.9~8.1ms inference speed.

I cut a pen refill tube into 2~3mm pieces as spacers.
I also needed to cut the top corner in this picture after raised the fan or else it's in the way when slide the cover back.
The metal is pretty soft, I used a pair of pliers, a flush cutter and a knife to get a better looking.

I doubt there is enough space using an extender, basically you'll end up with the extender board in the slot, an cable and three stacked PCBs the other end.

I wish I would have posted my question a few weeks ago! My TPU arrives today... But I have to wait a few weeks for my magic-blue-smoke adapter! I'll be very happy with those speeds. I was pessimistic about it recognizing both TPUs. That's great!

I'm assuming you raised the whole metal shrowd(not just the fan?) . Without taking my machine apart right now, I'm visualizing the tubes you cut resting on top of the screw posts on the board. And the screws that attach the shrowd fit inside the tubes/spacers, enabling them to screw into the posts with some small clearance. Is that correct? Can you circle the piece that you had to cut on the shrowd? I'm trying to visualize why one corner had to be cut. Sounds like your cut didn't interfere with the screw holes that attach the shrowd to the posts?

[Doug411]

If I described it correctly, and you put the spacers on top of the screw posts, did you just put them on top of the one corner, or all corners? If you just raised the one corner, could you have bent it down versus cutting it?

[jianhuiz]

I was reluctant climbing up to disconnect the box (another flaw that the ethernet cable is supper hard to pull out due to the tight space to reach the clip), but let me do it now and get you some pictures.

[jianhuiz]

All corners. Bend the plate can block the fan as well.
It blocks the chassis from closing because it's higher now, almost touching the back cover.

[Doug411]

Thanks so much! That helps. Nicely done. I did end up buying one of those extenders off of Amazon. It's not very long. I was hoping I could bend/twist the ribbon and have the coral and extender card sit where there is space for the U.2 drive. However I'm no electronics wizard. I'm afraid of it shorting the motherboard. I'm not sure how to attach it so that it doesn't cause harm (not sure It's long enough anyway) . I'll probably end of doing the exact same thing you did.
