Asus hyper m.2 x16 card v2 put it on a server

Here we go, I have to put these card on to my server with C620 chipset. I need fast local storage.
The card is not very expensive but i need 4×4 TB SSD on these server. So we started with a simple test. I bought 4x 16 GB Optane SSD for under 14 $ per piece. When it runs with this SSD so it will run also with the big ones.
That this runs we need a chipset that supports bifurcation with PCIe. With bifurcation you can split your 16x PCIe lane into 2×8, 4x4x4x4x or 8x4x4x. We need 4x4x4x4x every SSD needs 4x PCIe lanes. Would you read more about this topic look here

I have not really enough space. On this server there are also 4x 2080 TI graphics cards. It was very close that the card fit in it.

Next step was to configure the BIOS(UEFI) to talk correctly to this card. The automatic mode is not working. In automatic mode it detect only one SSD, the first one on the Asus card.

I used on the motherboard slot 10, this information is important to configured PE3 on CPU2 correct. We look in the manual of the motherboard to see which slot is connected with the CPU. Slot11 is not working there is not enough PCIe lanes only 4x. We need 16x to split into 4x4x4x4x
Let´s jump in to the BIOS.

On the BIOS follow the rabbit pictures.

We have to choose the right CPU. We use PE3 on CPU2

Change the IOU2 from Auto to 4x4x4x4, every SSD should runs with 4x PCIe lanes.

That was it.

Check under Linux with the command dmidecode -t 9
