NVDIMM Question

I have some Micron DDR4 NVDIMMs, PowerGEMs, and cables. I’m trying to get them working on a Supermicro X11SPL.

Everything seems to be working except for the actual saving process. When power is removed it looks like there is no power provided to the DIMMs.

I bought the cables from DigiKey since there are no “official” cables to be found anywhere but I suspect that the pin out of the cables I have may not be correct.

Does anyone have an official cable they could check for the correct wiring?

Thanks!

What cable did you bought? And does it compatible? I am trying to install same nvdimm, but it is so hard to find cable :(

I bought these:


Note that you need to rollover the pinout on one end. These come wired as straight through.

So:

Pin 1 to Pin 6
Pin 2 to Pin 5
Pin 3 to Pin 4
Pin 4 to Pin 3
Pin 5 to Pin 2
Pin 6 to Pin 1
