I have an ASUS B550i Rog Strix Motherboard paired with an NZXT H1 case.
If you're not familiar with the case it comes pre-configured with a Gen 3 riser card.
The nvme2 slot on the motherboard is GEN4 PCI-E x4 (The one on the top of the MB)
I am thinking of buying a GEN4 NVME drive (Either the Samsung 980 Pro or WD SN850). I know the real-life performance gains are in my head but my head wants to be fast. (in reality, I need a bigger NVME drive and why not go for GEN4 at comparable prices to GEN3)
Under the assumption that my GPU an RTX 3070 is running on a GEN 3 Riser Card will the GEN4 compatible M2 slot also be running PCI-E 3 speed. Is there any way to configure the M2 slot separately (in bios) from the PCI-E lanes that feed the GPU (I am guessing if I made the PCI-E slot Gen4 in bios) that the GPU wouldn't work because of the GEN 3 Riser card connected to it?
In summary, want to know if I connect a GEn4 NVME to the motherboard will it works as advertised, or will the fact that the GPU is on a PCIE3 riser fubar this without upgrading the riser.
Thanks, guys and have at it.
