So, I inherited an Intel Nuc 9 Extreme Kit from a project I was working on, and found an Asus Hyper M.2 board to put in it.

The Nuc already had a Gigabyte GP-GSM2NE3512GNTD in it, so that's set up as the cache.

 

I've picked up a couple of Kingston SNV2S/1000G drives to put in the Hyper card, but I can only manage to see one drive in it.

 

The BIOS has Auto / 16 / 2 x 8 / 8 + 2x4 options for the PCIe bifurcation settings, all of which I've tried.

The drives are in slots 1+3, though I've tried different configurations as well.

 

I can only see one of the Kingston drives at a time.

Any ideas as to the ridiculously simple thing I'm missing here?

Others in google searches have reported this card as not being compatible even with the PCIe bifurcation settings being available. You can try and make sure it's updated to the latest BIOS and see if that helps. If it doesn't, you can obtain a card like this: https://www.newegg.com/p/17Z-000F-002P9 which has it's own chip to handle the splitting.

I have a couple of these on a Supermicro X10+ System. I had issues seeing the ssd's until I realized that there was a logic to the madness.... In my case:

 

1x nvme:

    bios bifurcation = 16x

    nvme slot = 1

 

2x nvme:

    bifurcation = 8x/8x

    nvme slot = 1 and 3

 

3x nvme:

    bifurcation = 8x/4x/4x

    nvme slot = 1, 3 and 4

 

4x nvme:

    bifurcation = 4x/4x/4x/4x

    nvme slot = 1, 2, 3, 4

 

Any other configuration than this and it usually resulted in unhappy results.

You would think that simply setting it to 4x/4x/4x/4x and adding any number of nvme drives would just work, but it did not.

Thanks peeps.

Looks like a no go, unfortunately.

 

Appreciate the input.
