Hello,

I just bought a new adapter but I'm wondering if I can use it in my motherboard. Specs:

Mobo: GA x79 UD5
CUP: 3930k

I'm currently using a simple LSI Jbod adapter for 8 SSDs. But I want to upgrade to NVMe for music production. I'm not booting off the NVMe's or wanting RAID, I'm using a regular SATA 3, 850 pro ssd for Windows 10 OS. These are strictly to be read from. I realized after the fact that this was cheap for a reason; doesn't have it's own bifurcation chip.

Here is my adapter:

Xiwai 4X NVME M.2 AHCI to PCI-E Express 3.0 Gen3 X16 Raid Card with Fan VROC Raid0 Hyper Adapter

Also, is bifurcation the norm for new moterboards, or am I going to have to be picky when I upgrade my mobo/rig?

Thanks!

Does my Mobo have a modded BIOS for bifurcation?

There is a topic on in, but no files available since its user own links and cant be recovered, Lost as been offline since January, still there's some guidance there on the subject.

Gigabyte GA-X79-UD5 PCIE Bifurcation (2)

Thanks for alll that info. I just have a few more questions:

1. If I get an adapter with bifurcation onboard, will there be any bottlenecks (assuming all drives are only pcie 3.0)?

2. Can I run a dual PCIe NVMe adapter with just two drives, or does this also need bifurcation? If so, can I also add another dual PCIe NVMe adapter spread across my motherboard?

3. Can I run a PCIe 4.0 nvme in a 3.0 adapter, or is this motherboard too old? I think I know the answer is yes, but I'll only get 3.0 speeds.




Thank you!
