Hi dear Forum-Community,
im somehow very lost in this topic regarding BIOS modification etc, So I really hope to get help.
I have build a Server with 2x Xeon (6230) and no "normal" SSD installed.
Instead of "normal" SSD Im using NVME Card "ASRock Ultra Quad m.2" with 4 SSD installed in them (4x Mushkin Pilot-E 4 TB)
In total I got 16 TB SSD (2x ASRock Ultra Quad m.2 with each containing 4 SSDs).
I wanted to run this 16 GB SSD in RAID 01 through Windows Server 2019.

When I tested the ASRock Ultra Quad m.2 with my X99A Godlike Gaming Motherboard, it only recognized 1 of the SSD (I have put it into 16x Lane, Second Lane for GPU originally).
According to Gigabyte there are 3x 16x Pcie Lanes. So I use 2 of them for ASRock Ultra Quad m.2 and 1 for GPU. The Lanes im intending to use on the Gigabyte MD71-HB0 is the following: 1st Lane GPU, 2nd+3rd Lane (x16) Asrock Ultra Quad M.2 Cards. I want to boot from these SSDs.

Will the Gigabyte MD71-HB0 recognise the 8 SSD immediately? I read that i have to change the lanes to x4x4x4x4 in order to get all SSDs going.
Is this option already included in the Bios of Gigabyte Motherboard? Or is there a Bios modification required?
If Bios modification required (bifurication) is it possible to please guide how to do it step by step?
Or if someone can build a bios file with the modification already in it I would be really grateful - either way is really helpfull for me.
If the option of changing pcie-lanes to x4x4x4x4 already exist in Gigabyte MD71-HBO then please let me know, as my Mobo seems to be broken and will be replaced. So i couldnt get into Bios. I know that the option is not existing in msi godlike gaming x99a Mainboard (through bifurication its however possible to get the lanes to x4x4x4x4) with working ssd:)

So I hope you guys got my question(s) and willing to help. Im really thankfull to each and every one of you.
Thank you very much for your efforts and time.

@Fernando Hi thanks for your fast reply. Regarding your first question: Actually the RAID is only for securing the data. So if RAID is not possible its also not that much of a problem. I thought of using Windows RAID. I doubt that Intel raid will be possible with these SSD (according to my info Intel raid will only work with Intel SSDs - im open for any correction :)
Regarding the 2nd question: I hope to get more performance typical for nvme ssd compared to the "normal" ssd speeds. Thats just all :)

Yes you are right its 16TB instead 16Gb...

I would be very happy if all the 8 SSDs get recognized no matter of RAID working or not. Main Goal is to get all 8 SSS working on this card instead of currently 2 (1 for each pcie) :)

Hi @Fernando Thanks for your reply. Point 1: Thanks for the info :) Point 2: ok perfect, then i would like to create Intel Raid (is this the so called VROc?)
Point 3: This is true and was also not intended. The speed of the nvme is fast enough:)

So what do you think should i do now?

IIO Bifurcation Auto Detect - Is currently set to Enabled = Auto Set Bifurcation (Disabled = Manually set)

Can you see submenu >> Socket Config >> IIO Configuration >> Socket 0-3 config submenus?
If not, but you can see some of that, let me know how far into that menu string can you see?

Socket 2+3 are all on auto, here is what is set by default for Socket 0+1. All can be adjusted by me, or probably made visible to you as well so you can adjust
