with the DMM it looks like pins 1-5 could be COM and 6-9 as +12V.
Pin 10 is not obvious to me.
Some remarks after watching the video from the Japanese user:
* It was bought from a seller in the Kanagawa prefecture (not from US as OP or UK like mine).
* Quite different S/N from mine, I'd say...
update: just received the board. The 40G MAC is definitely for infiniband; there's a jumper labeled as such.
I'm wondering why the second 25G interface isn't present on the X10SDV-CIBF-AM041 because I'd assume it has the same Mellanox ConnectX-4 lx controller.
The Japanese user also...
I bought this board from a seller in the UK. It was advertised as in working condition and with a Xeon D-1581. Will keep you informed on my progress to get it up and running once I receive it.
From the photos in the listing, it looks like the power connector closely resembles HP backpane 10-pin...
This refurbished board catches my interest due to the very affordable price.
Can anyone tell me if the DC_IN1 connector is optional? I.E. can I power the board with only a 12V power supply comnected to P12V_AUX1 - like is possible on many SuperMicro MITX boards?
the bolded part interests me; I'm trying to revive/refresh my A1SAi-2750F, and I got a Samsung 970 Pro 512GB inteded as data storage for ESXi, inserted on a 1U PCIe M2 M-slot adapter. However, nothing gets detected in the BIOS and in ESXi 7.
lspci doesn't show anything. I've updated the BIOS...
Ziptie was the original plan, but the heatsink unexpectedly is flat at the top. This means no air will pass between the heatsink fins when forced from above, and I fear very poor cooling performance.
I haven't seen this type of heatsink before on supermicro boards, and the review of the 16 core...
Yes the cse-e300 seems to do the job, but I was hoping to avoid it as it is reported to be rather noisy. Sounds like there might not be many other options unfortunately.
Just received this motherboard, and am bummed that the cpu heatsink is completely flat at the top. The fins are aligned perpendicular to the rear IO panel, and the mini-itx case I intended to use only really allows for airflow directly from above the cpu or parallel to the rear IO panel.
